　　Foreword

　　ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

　　International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

　　The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

　　Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

　　ISO 37120 was prepared by Technical Committee ISO/TC 268, Sustainable development in communities

　　Working Group 2 Urban Indicators.

　　ISO 37120 consists of the following parts, under the general title Sustainable development in communities — Indicators for city services and quality of life.

　　Introduction

　　Cities need indicators to measure their performance. Existing indicators are often not standardized, consistent, or comparable over time or across cities

　　As part of a new series of International Standards being developed for a holistic and integrated approach to sustainable development and resilience, this set of standardized indicators will help support sustainable development and resilience in cities.

　　These indicators can be used to track and monitor progress on city performance. In order to achieve sustainable development, the whole city system needs to be taken into consideration. Planning for future needs must take into consideration current use and efficiency of resources in order to better plan for tomorrow.

　　The indicators and associated test methods in this International Standard have been developed in order to help cities:

　　a) measure performance management of city services and quality of life over time;

　　b) learn from one another by allowing comparison across a wide range of performance measures; and,

　　c) share best practices.

　　The indicators in this International Standard have been selected to make reporting as simple and inexpensive as possible, and therefore reflect an initial platform for reporting. Further development of indicators to support sustainable development and resilience in cities is on-going in TC268.

　　The indicators are structured around themes. Recognizing the differences in resources and capabilities of cities worldwide, the overall set of indicators for city performance has been divided into “core” indicators (those implementing this International Standard shall follow) and “supporting” indicators, (those implementing this International Standard should follow). Both core and supporting indicators are listed in Annex A, Table A.1. In addition, profile indicators, which provide basic statistics and background information to help cities determine which cities are of interest for comparisons, are included in Annex B, Table B.1, as a reference.

　　In this International Standard, the following verbal forms are used:

　　— “shall” indicates a requirement;

　　— “should” indicates a recommendation;

　　— “may” indicates a permission;

　　— “can” indicates a possibility or a capability.

　　DRAFT INTERNATIONAL STANDARD ISO/DIS 37120

　　Sustainable Development in Communities —Indicators for City Services and Quality of Life

　　1 Scope

　　This International Standard defines and establishes methodologies for a set of indicators to steer and measure the performance of city services and quality of life. It follows the principles set out and can be used in conjunction with ISO 37101:— Sustainable development in communities — Management systems — General principles and requirements when published.

　　This International Standard is applicable to any city, municipality or local government that undertakes to measure its performance in a comparable and verifiable manner.

　　2 Normative references

　　The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

　　ISO 15392:2008, Sustainability in building construction — General principles

　　ISO 26000:2010, Guidance on Social Responsibility

　　3 Terms and definitions

　　For the purposes of this document, the terms and definitions given in ISO 37101, and the following apply.

　　3.1

　　city

　　urban community falling under a specific administrative boundary, commonly referred to as a city, municipality or local government

　　3.2

　　indicator

　　a quantitative, qualitative or descriptive measure

　　[SOURCE: ISO 15392:2008, 3.14]

　　Indicators in this standard are divided into:

　　core indicators: indicators that are required to demonstrate performance in the delivery of city services and quality of life.

　　© ISO 2013 – All rights reserved

　　supporting indicators: indicators that are recommended to demonstrate performance in the delivery of city services and quality of life.

　　profile indicators: indicators that provide basic statistics and background information to help cities determine which cities are of interest for peer comparisons. Profile indicators are used as an informative reference.

　　3.3

　　full-time enrolment definition

　　enrolment in school for every full school day in a week over the entire school year

　　3.4

　　part-time enrolment

　　enrolment in school for at least a half-day over the entire school year

　　Example: A student is counted as enrolled part-time if he/she is enrolled in school for a half-day, but is not counted as enrolled if he/she is only enrolled for 0,25 of a day.

　　3.5

　　primary education

　　primary education (also referred to as elementary school) is considered to be the first stage of ‘basic education’.

　　Note: Primary Education typically covers six years of full-time schooling with the legal age of entrance normally being not younger than 5 years or older than 7 years. Primary education typically lasts until age 10 to 12. Primary education shall refer to children ages 5-12 years or 1st grade through 5th or 6th grade as defined by local education systems.

　　[SOURCE: UNESCO Institute for Statistics, UOE data collection on education systems, 10.1]

　　3.6

　　secondary education

　　Secondary education is considered to be the second stage of basic education. Secondary education marks the end of compulsory education where it exists.

　　Note: Students usually enter between age 10 and 13 (age 12 being the most common). Secondary education usually ends 12 or 13 years after the beginning of primary school (or around age 18); however, systems can range between ending 11 to 14 years after beginning school (or around age 17 to 20). Secondary education also refers to 6th grade (or 7th grade) to 12th grade as defined by local education systems.

　　3.7

　　tertiary education

　　Tertiary education is provided by universities and other higher education institutions following secondary schooling.

　　3.8

　　hazardous waste

　　waste that is potentially harmful to human beings, property or the environment [SOURCE: ISO 18113-1:2009, 3.22]

　　3.9

　　performance indicators for sustainable development

　　quantitative, qualitative or descriptive measures to periodically assess the performances of a city referring to its Sustainable Development.

　　Note:

　　1. The indicators provide information about the condition of the Sustainable development of a city.

　　2.

　　Indicators are intended to explain how the development in cities is changing over the time.

　　3.10

　　solid waste

　　non-soluble, discarded solid materials, including sewage sludge, municipal garbage, industrial wastes, agricultural refuse, demolition wastes and mining residues

　　3.11

　　NO2 (Nitrogen Dioxide)

　　A reddish-brown gas with a pungent odour that is produced when nitric oxide (NO) is mixed with air quickly combining with oxygen and forming nitrogen dioxide (NO2).

　　NOTES:

　　1. NO2 is an odourless, colourless gas which is produced during high temperature burning of fuel in, for example, cars and other road vehicles, heaters and cookers.

　　2. Most nitrogen dioxide in the atmosphere is formed from the oxidation of nitric oxide (NO) as indicated in the main definition above, although some is release directly from sources. Nitrogen dioxide is a strong oxidizing agent that reacts in the air to form corrosive nitric acid, as well as toxic organic nitrates. It also plays a major role in the atmospheric reactions that produce ground-level ozone or smog. It is also a precursor to nitrates, which contribute to increased respirable particle levels in the atmosphere.

　　3.12

　　SO2 (Sulphur Dioxide)

　　A pungent smelling colourless gas that is formed naturally by volcanic activity, and is a waste gas produced by burning coal and oil and by many industrial processes. Sulphur dioxide is also a hazardous air pollutant and a major contributor to acid rain.

　　NOTE: Sulphur dioxide can be oxidized to sulphur trioxide, which in the presence of water vapour is readily transformed to sulphuric acid mist. SO2 can be oxidized to form acid aerosols. SO2 is a precursor to sulphates, which are one of the main components of respirable particles in the atmosphere. SO2 can be also found in liquid form.

　　3.13

　　O3 (Ozone)

　　Ozone (O3) is the tri-atomic form of molecular oxygen (O2). It is a toxic bluish, unstable gas, with pungent odour, found naturally in the atmosphere, particularly in the stratosphere.

　　NOTE: Ozone at ground level is one of the two major constituents of photochemical smog. It is formed by the reaction with sunlight (photochemical reaction) of pollutants such as nitrogen oxides (NOx) from vehicle and industry emissions and volatile organic compounds (VOCs) emitted by vehicles, solvents, and industry.

　　3.14

　　Vascular plants (tracheophytes)

　　Plants that can internally transport water and food. Vascular plants are also known as tracheophytes.

　　3.15

　　Bird (class Aves)

　　Any of the 9,600 living species unique in having feathers, the major characteristic that distinguishes them from all other animals.

　　NOTE: A more elaborate definition would note that they are warm-blooded vertebrates more related to reptiles than to mammals and that they have a four-chambered heart (as do mammals), forelimbs modified into wings (a trait shared with bats), beak, a hard-shelled egg, and keen vision, the major sense they rely on for information about the environment.

　　3.16

　　Butterfly (superfamily Papilionoidea)

　　An insect with two pairs of large wings that are covered with tiny scales, usually brightly coloured, and typically held erect when at rest. Butterflies fly by day, have clubbed or dilated antennae, and usually feed on nectar.

　　NOTE: Butterflies, along with the moths and the skippers, make up the insect order Lepidoptera. They are nectar-feeding insects. Butterflies are nearly worldwide in their distribution. The wings, bodies, and legs, like those of moths, are covered with dustlike scales that come off when they are handled. Unlike moths, butterflies are active during the day and are usually brightly coloured or strikingly patterned. Perhaps the most distinctive physical features of the butterfly are its club-tipped antennae and its habit of holding the wings vertically over the back when at rest.

　　4 City Indicators

　　This International Standard is designed to assist cities in steering and assessing the performance management of city services and quality of life and considers sustainability as its general principle and resilience as a guiding concept in the development of cities. All indicators shall be reported on an annual basis.

　　Those implementing this International Standard shall report on all core indicators listed in Clauses 5 to 21 of this International Standard.

　　The core indicators described in this International Standard are considered essential for steering and assessing the performance management of city services and quality of life.

　　In order to promote best practice, cities should also report on the supporting indicators given in Clauses 5 to 21 of this International Standard.

　　The core and supporting indicators are classified into themes according to the different sectors and services provided by a city. The classification structure is used solely to denote the services and area of application of each type of indicator when reported on by a city. This classification has no hierarchical significance and is organized alphabetically according to themes.

　　Indicators under each theme, where possible, were selected and paired on the basis of input and outcome indicators for further contextual analysis.

　　When interpreting the results of a particular service area, it is important to review the results of multiple types of indicators across themes; to focus on a single indicator can lead to a distorted or incomplete conclusion. Elements of aspiration must also be taken into consideration in the analysis.

　　Users may also consider the following aspects: indicators can be aggregated to larger administrative areas (ex. region, metropolitan areas etc.); since some indicators are indirectly linked to sustainability, there is a need to consider the resource efficiency of a city; indicators can be grouped together for analysis when taking into consideration holistic characteristics of a city; and, this set of indicators may be complemented by other indicator sets in order to have a more comprehensive holistic approach to analysis on sustainability.

　　Furthermore, it is also important to acknowledge potential antagonistic effects of the outcome of particular indicators, either positive or negative, when analysing results. For example, an increase in air connectivity and the number of automobiles per capita will potentially result in increased levels of PM10 and greenhouse gas emissions.

　　NOTE: For data interpretation purposes cities shall take into consideration contextual analysis when interpreting results. The local institutional environment may affect the capacity to apply indicators. In some cases, services may be delivered by the private sector or the community itself.

　　Table B.1 lists a series of profile indicators for reference purposes.

　　5 Economy

　　5.1 City’s unemployment rate

　　5.1.1 General

　　This is a core indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The unemployment rate is considered one of the single, most informative labour market indicators reflecting the general performance of the labour market and the health of the economy as a whole. It is used to measure a city’s unutilized labour supply and track business cycles. When economic growth is strong, unemployment rates tend to be low and when the economy is stagnating or in recession, unemployment rates tend to be higher.

　　5.1.2 Core indicator requirements

　　A city’s unemployment rate shall be calculated as the number of working-age city residents who during the survey reference period were not in paid employment or self-employment, but available for work, and seeking work (numerator) divided by the total labour force (denominator). The result shall be multiplied by 100 and expressed as a percentage.

　　Unemployment shall refer to individuals without work, actively seeking work in a recent past period (past four weeks), and currently available for work. Persons who did not look for work but have a future labour market stake (arrangements for a future job start) are counted as unemployed (International Labour Organization). Discouraged workers or hidden unemployed shall refer to persons who are not actively seeking work because they believe the prospects of finding it are extremely poor or they have restricted labour mobility, face discrimination, and/or structural, social,

　　and cultural barriers – are not counted as unemployed or as part of the labour force. Not actively seeking work shall refer to people who have not taken active steps to seek work (i.e. job searches, interviews, informational meetings etc.) during a specified recent period (usually the past four weeks).

　　Labour Force shall refer to the sum of the total persons employed and unemployed who are legally eligible to work.

　　5.2

　　Commercial/Industrial Assessment as a percentage of total assessment

　　5.2.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE Assessment is an important measure of a municipality’s revenues as it forms the foundation of property taxes. Assessment growth provides an indication of how the base, upon which taxes are levied, is changing over time. Commercial/Industrial Assessment as a percentage of total assessment provides an understanding of the mix of assessment as well as the stability of the assessment base. A downward trend in the proportion of commercial and industrial assessment could indicate an eroding economic base. Over reliance on residential assessment impacts affordability.

　　5.2.2 Core indicator requirements

　　The commercial/industrial assessment as a percentage of total assessment shall be expressed as the total assessed value of commercial and industrial properties (numerator) divided by the total assessed value of all properties (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Commercial and industrial properties shall refer to those which have been designated by the city for commercial and industrial use.

　　NOTE Assessment methods may vary from one jurisdiction or country to another, including the market- oriented method, the profit-oriented method and the cost-oriented method.

　　5.3 Percentage of city population living in poverty

　　5.3.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The percentage of the city’s population living in poverty is an indicator of social equity and reflects levels of economic and social marginality and/or inclusiveness in a city. Eradication of poverty is an essential component of the Millennium Development Goals[22].

　　5.3.2 Core indicator requirements

　　The percentage of city population living in poverty shall be calculated as the number of people living below the poverty threshold (numerator) divided by the total current population of the city (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　The total number of persons in the city living below the poverty threshold shall first be determined by multiplying the number of city households living at or below the poverty threshold by the current average number of persons per household for that city.

　　NOTE The poverty threshold for each country is recorded by the World Bank, which can be viewed through its website at: www.worldbank.org (search for PovertyNet) or directly on the PovertyNet website at: www.povertynet.org[34] where, the poverty threshold for households is specified as persons unable to adequately provide themselves over a 12 month period with water, food, shelter, and other basic needs for a healthy life.

　　5.3.3

　　Data interpretation

　　Applying current average persons per household figure to all households can lower distinctions between household size in poor and more affluent households.

　　5.4 Percentage of persons in full-time employment

　　5.4.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The percentage of the city population in full-time employment is an indicator of the economic health of the city and the success of city economic policy.

　　5.4.2 Supporting indicator requirements

　　The percentage of persons in full-time employment shall be calculated as the number of persons in full- time employment (numerator) divided by the total city population (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　The number of persons residing in the city in full-time employment shall include those that are self- employed and shall only include the residents that work a minimum of 35 hours a week in one job and who are of legal working age.

　　NOTE 1 City population has been used as the denominator for this indicator instead of workforce given that population will be known for most cities. This indicator is dependent on the government agency charged with the responsibility of collecting relevant employment and population data and the precise nature of the available data.

　　NOTE 2 Employment is a formal labour market concept which is often complicated in developing countries with a large informal sector of the city economy.

　　NOTE 3 The Social Responsibility core subjects on Human Rights and Labour Practices from ISO 26000 shall be considered, particularly in regards to child labour.

　　The International Labour Organization (ILO) Fundamental Principles and Rights at Work (FPRW) include the elimination of child labour alongside the right to freedom of association and collective bargaining, elimination of forced labour, and the elimination of discrimination in employment or occupation. These fundamental principles and rights at work are mutually interdependent. Violation of one category of rights at work often has an adverse impact on the respect and realization of the others. Vice versa, recognition, promotion and implementation of one category of rights can have a beneficial impact on the respect and realization of the others.

　　Over the years the international community has developed a framework of international standards which seek to protect children from child labour, in particular the two important ILO Conventions on the subject and more generally the UN Convention on the Rights of the Child[45]. Whilst some progress is being made in reducing child labour, in too many cases the rights contained in these international standards are still not fully applied in practice and enforced. Users of this standard are encouraged to keep these principles in mind.

　　5.5 Youth unemployment rate

　　5.5.1

　　General

　　This is a supporting indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The unemployment rate is probably the best-known and most used labour market performance indicator. Youth Unemployment Rate is key indicator for quantifying and analyzing the current labour market trends and challenges of young people. Young men and women today face increasing uncertainty in their hopes of undergoing a satisfactory transition in the labour market, and this uncertainty and disillusionment can, in turn, have damaging effects on individuals, communities, economies and society at large. Unemployed or underemployed youth are less able to contribute effectively to community and national development and have fewer opportunities to exercise their rights as citizens. They have less to spend as consumers, less to invest as savers and often have no “voice” to bring about change in their lives and communities. Widespread youth unemployment and underemployment also prevents companies and countries from innovating and developing competitive advantages based on human capital investment, thus undermining future prospects. Knowing the costs of non-action, many governments around the world do prioritize the issue of youth employment and attempt to develop pro-active policies and programmes.

　　5.5.2 Supporting indicator requirements

　　Youth unemployment rate shall be calculated as the total number of unemployed youth (numerator) divided by the youth labour force (denominator). The result shall be multiplied by 100 and expressed as a percentage.

　　Unemployed youth shall refer to individuals above the legal working age and under 24 years of age who are without work, actively seeking work in a recent past period (past four weeks), and currently available for work. Youth who did not look for work but have a future labour market stake (arrangements for a future job start) are counted as unemployed (International Labour Organization). Discouraged workers or hidden unemployed shall not be counted as unemployed or as part of the labour force. Not actively seeking work shall refer to people who have not taken active steps to seek work (i.e. job searches, interviews, informational meetings etc.) during a specified recent period (usually the past four weeks).

　　Youth labour force shall refer to all persons above the legal working age and under 24 years of age, who are either employed or unemployed over a specified reference period.

　　Note: Countries vary somewhat in their operational definitions of youth, In particular, the lower age limit for young people is usually determined by the minimum age for leaving school, where this exists.

　　5.6 Number of businesses per 100 000 population

　　5.6.1 General

　　This is a supporting indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The number of businesses per 100 000 can inform a city’s level of economic activity and economic performance. It provides one indication of the overall business climate in a jurisdiction, and attitudes towards entrepreneurship. Strong entrepreneurial activity is closely associated with a dynamic and growing economy. The number of businesses is also used to inform competitiveness of a city. The number of businesses reflects both the number of new businesses created and the survival of existing businesses.

　　5.6.2 Supporting indicator requirements

　　The number of businesses per 100 000 population shall be calculated as the total number of businesses in a city (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of businesses per 100 000 population.

　　Businesses shall refer to companies or enterprises. The enterprise is the smallest combination of legal unit, that is, an organizational unit producing goods or services. Business can either be categorized as simple (one operating entity) or complex (multiple operating entities).

　　5.7 Number of new patents per 100 000 population per year.

　　5.7.1.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　The definitions of primary and secondary school detailed in Clauses 3.5 and 3.6 shall apply.

　　Enrolment in public and private schools should be reported, and cities shall note if private school data are included. In many cities, private schools are a significant component of education in the city. Private schools shall be recognized as providing real, bona fide education; many ministries or departments of education have a program that recognizes such schools. Enrolment in religious schools and home schools should be included if they are recognized.

　　One part-time enrolment of a half-day or more shall be counted as a full-time enrolment.

　　If the geographies of school districts and the city are different, best judgment should be used to relate enrolment data to the city boundaries.

　　6.2.2 Core indicator requirements

　　The survival rate of primary education shall be calculated as the total number of students belonging to a school-cohort who complete the final grade of primary education (numerator) divided by the total number of students belonging to a school-cohort, i.e. those originally enrolled in the first grade of primary education (denominator). The result shall then be multiplied by 100 and expressed as a percentage. The survival rate of primary education shall be expressed as the percentage of a cohort of students enrolled in the first grade of primary education who reached the final grade of primary education.

　　Survival rates for the private education sector should be reported, if known. The user of this International Standard shall note if private school data are included.

　　NOTE 1 This indicator measures students belonging to a school-cohort who has reached each successive grade of primary education without failing or moving to another jurisdiction.

　　NOTE 2 This methodology is adapted from UNESCO Education Indicator Technical Guidelines[4].

　　EXAMPLE If the city reporting year is 2012 and primary education lasts five years, report the percentage of students that entered primary education in 2006 and reached the final grade of primary education in 2011.

　　6.2.3 Data sources

　　Since the calculation of this indicator is based on student-flow rates, the reliability of the survival rate depends on the consistency of data on enrolment and repeaters (those who repeat one or more grades) in terms of coverage over time and across grades.

　　NOTE 1 In most cities, survival rates will only be readily available for public school systems. NOTE 2 Data on school enrolment is usually recorded by the Ministry or Department of Education.

　　6.3 Percentage of students completing secondary education: survival rate

　　Private educational facilities shall not be included in the student/teacher ratio.

　　One part-time student enrolment shall be counted as one full-time enrolment; in other words a student who attends school for half a day should be counted as a full-time enrolment. If a city reports full-time equivalent (FTE) enrolment (where two half day students equal one full student enrolment), this shall be noted.

　　The number of classroom teachers and other instructional staff (e.g. teachers’ aides, guidance counsellors), shall not include administrators or other non-teaching staff. Kindergarten or pre- school teachers and staff shall not be included.

　　The number of teachers shall be counted in fifth time increments, for example, a teacher working one day per week should be counted as 0,2 teachers, and a teacher working three days per week should be counted as 0,6 teachers.

　　6.4.3 Data sources

　　The number of full-time equivalent primary school classroom teachers and the number of enrolled primary school students should be collected from the local public school system or Ministry of Education.

　　6.4.4 Data interpretation

　　The student/teacher ratio reflects teacher workload and the availability of teachers' services to their students. The lower the student/teacher ratio, the higher the availability of teacher services to

　　students. The student/teacher ratio has implications not only for the cost of education, but also for the quality. Higher educational attainment is correlated with a lower student/teacher ratio.

　　8 Environment

　　8.1 Fine Particulate Matter (PM 2.5) Concentration

　　8.1.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE: Fine particulate matter can cause major health problems in cities. According to the WHO, any concentration of particulate matter (PM) is harmful to human health. PM is carcinogenic and harms the circulatory system as well as the respiratory system. As with many other air pollutants, there is a connection with questions of environmental justice, since often underprivileged citizens may suffer from stronger exposure. The evidence on PM and its public health impact is consistent in showing adverse health effects at exposures that are currently experienced by urban populations in both developed and developing countries. The range of health effects is broad, but are predominantly to the respiratory and cardiovascular systems.

　　8.1.2 Core indicator requirements

　　Fine Particulate Matter (PM2.5) concentration shall be calculated as the total mass of collected particles that are 2.5 microns or less in diameter (numerator) divided by the volume of air sampled (denominator). The result shall be expressed as the concentration of PM2.5 in micrograms per standard cubic meter (μg/m3).

　　The method for measurement shall involve the use of an air sampler which draws ambient air at a constant flowrate into a specially shaped inlet where the suspended particulate matter is inertially separated into one or more size fractions within the PM2.5 size range. The 24-hour (daily) measurements of PM 2.5 concentrations are forwarded to a database where yearly summaries for each monitoring stations are computed.

　　NOTE: Since data for PM2.5 is not readily available, levels are often calculated on the basis of PM10 emission and this is reported as a separate indicator.

　　8.2 Particulate Matter (PM10) Concentration

　　8.2.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator (unless reporting on PM2.5 under 8.1) in accordance with the following requirements.

　　NOTE The evidence on airborne Particulate Matter (PM) and its public health impact is consistent in showing adverse health effects at exposures that are currently experienced by urban populations in both developed and developing countries. PM pose a health concern because they can be inhaled into and accumulate in the respiratory system.

　　People with heart or lung disease, older adults, and children are considered at greater risk to particle pollution. Long-term exposures (annual mean) to particles, such as those experienced by people living for many years in areas with high particle levels, have been associated with problems such as reduced lung function and the development of chronic bronchitis - and even premature death. Short-term exposures (24 h) to particles can aggravate lung diseases, causing asthma attacks and acute bronchitis, and may also increase susceptibility to respiratory infections. High particle pollution in major cities like Hong Kong, Beijing, etc. have major negative impacts on economic/business growth due to decline in foreign investors. According to the World Health Organization[12], air pollution is estimated to cause approximately 2 million premature deaths worldwide per year. In many cities, the average levels of PM10 exceed 70 μg per cubic meter (μ/m3).

　　8.2.2 Core indicator requirements

　　Particulate Matter (PM10) concentration shall be calculated as the total mass of collected particles in the PM10 size range (numerator) divided by the volume of air sampled (denominator). The result

　　shall be expressed as the concentration of PM10 in micrograms per standard cubic meter (μg/m3).

　　The method for measurement shall involve the use of an air sampler which draws ambient air at a constant flowrate into a specially shaped inlet where the suspended particulate matter is inertially separated into one or more size fractions within the PM10 size range. The 24-hour (daily) measurements of PM10 concentrations are forwarded to a database where yearly summaries for each monitoring stations are computed.

　　NOTE Particulate matter is a mixture of microscopic solids and liquid droplets suspended in air. These particulates are made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, soil or dust particles, and allergens (such as fragments of pollen or mould spores). Coarse particles are greater than 2,5 microns and less or equal to 10 microns in diameter and are defined as “respirable particulate matter” or PM10. Sources of coarse particles include crushing or grinding operations, and dust from paved or unpaved roads.

　　8.3 Greenhouse gas emissions measured in tonnes per capita

　　8.3.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The greenhouse gas emissions from all activities within the city are an indicator of the adverse contribution the city is making to climate change.

　　8.3.2 Core indicator requirements

　　The greenhouse gas emissions measured in tonnes per capita shall be measured as the total amount of greenhouse gases in tonnes (equivalent carbon dioxide units) generated over a calendar year by all activities within the city, including indirect emissions outside city boundaries (numerator) divided by the current city population (denominator). The result shall be expressed as the total greenhouse gas emissions per capita in tonnes.

　　The total aggregate tonnage (expressed as equivalent carbon dioxide units of greenhouse gas) of greenhouse gas emissions shall be calculated for all activities within the city for the preceding 12 months.

　　The Global Protocol for Community-Scale GHG Emissions (GPC), (2012 Accounting and Reporting Standard) refers to a multi-stakeholder consensus-based protocol for developing international recognized and accepted community-scale greenhouse gas accounting and reporting. This protocol defines the basic emissions sources and categories within sectors for a community-scale GHG inventory, in order to standardize GHG inventories between communities and within a community over time. The protocol provides accounting methodologies and step-by-step guidance on data collection, quantification, and reporting recommendations for each source of emissions.

　　Both emissions sources and sector categorizations reflect the unique nature of cities and their primary emissions sources. These include emissions from: 1) Stationary Units, 2) Mobile Units, 3) Waste, and 4) Industrial Process and Product Use sectors. For further specifications, refer to the full

　　GPC methodology. Local governments shall be expected to provide information (i.e., quantified emissions) for each of these emission sources.

　　In order to address the issue of inter-city sources of emissions that transcend more than one jurisdictional body, the GPC integrates the GHG Protocol Scope definitions, as follows:

　　1. Scope 1 emissions: All direct emission sources from activities taking place within the community’s geopolitical boundary.

　　2.

　　Scope 2 emissions: Energy-related indirect emissions that result as a consequence of consumption of grid-supplied electricity, heating and/or cooling, within the community’s geopolitical boundary.

　　3. Scope 3 emissions: All other indirect emissions that occur as a result of activities within the community’s geopolitical boundary.

　　For step-by-step guidance on data and accounting collection, see Section 3 of the GPC. http://www.ghgprotocol.org/files/ghgp/GPC%20v9%2020120320.pdf

　　NOTE Greenhouse gases (GHGs) are gases in the atmosphere that absorb infrared radiation that would otherwise escape to space; thereby contributing to rising surface temperatures. There are six major GHGs: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). The warming potential for these gases varies from several years to decades to centuries.

　　Users may also consult the ISO 14064 series[82] on Greenhouse Gases for further guidance.

　　8.4 NO2 (nitrogen dioxide) concentration

　　8.4.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE: NO2 (nitrogen dioxide) is a major air pollutant, which can have significant impacts on human health and the environment. NO2 contributes to the formation of photochemical smog and at raised levels can increase the likelihood of respiratory problems. Nitrogen dioxide inflames the lining of the lungs, and it can reduce immunity to lung infections. This can cause problems such as wheezing, coughing, colds, flu and bronchitis. Increased levels of nitrogen dioxide can have significant impacts on people with asthma because it can cause more frequent and more intense attacks. NO2 chemically transforms into nitric acid and contributes to acid rain. Nitric acid can corrode metals, fade fabrics, and degrade rubber. When deposited, it can also contribute to lake acidification and can damage trees and crops, resulting in substantial losses.

　　8.4.2 Supporting indicator requirements

　　NO2 concentration shall be calculated as the sum of daily concentrations for whole year (numerator) divided by 365 days (denominator). The result shall be expressed as the annual average for daily NO2 concentration in μg/m3. The daily concentrations shall be determined by averaging the hourly concentrations throughout a 24 hour period from all monitoring stations within the city.

　　NOTE If local stations monitor O3 in parts per billion, the following conversion ratio to μg/m3 shall be used: 1 ppb = 2.00 μg /m3. The conversion assumes an ambient pressure of 1 atmosphere and a temperature of 25

　　degrees Celsius. The general equation is μg/m3 = (ppb)*(12.187)*(M) / (273.15 + °C) where M is the molecular weight of the gaseous pollutant. An atmospheric pressure of 1 atmosphere is assumed.

　　Users of this standard should also note the frequency of NO2 exposures. Peak exposure is determined by calculating the number of times the hourly mean exceeded 200 μg/m3 of NO2 in a calendar year. Long-term exposure is determined by calculating the number of times the daily mean exceeded 40 μg/m3 of NO2 in a calendar year.

　　8.4.3

　　Data sources

　　Hourly average concentrations are measured by monitoring equipment and reported to Air Quality monitoring authority (i.e., City Environment Office, National Environment Office, etc.)

　　8.5 SO2 (sulphur dioxide) concentration

　　8.5.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE: SO2 (sulphur dioxide) is a major air pollutant, which can have significant impacts on human health and the environment. Health effects caused by exposure to high levels of SO2 include breathing problems, respiratory illness, changes in the lung's defenses, and worsening respiratory and cardiovascular disease. People with asthma or chronic lung or heart disease are the most sensitive to SO2. It also damages trees and crops. SO2, along with nitrogen oxides, are the main precursors of acid rain. This contributes to the acidification of lakes and streams, accelerated corrosion of buildings, reduced visibility and deforestation. SO2 also causes formation of microscopic acid aerosols, which have serious health implications as well as contributing to climate change.

　　8.5.2 Supporting indicator requirements

　　SO2 concentration shall be calculated as the sum of daily concentrations for the whole year (numerator) divided by 365 days. The result shall be expressed as the annual average for daily SO2 concentration in μg/m3. The daily concentration shall be determined by averaging the hourly concentrations throughout a 24 hour period from all monitoring stations within the city.

　　Users of this standard should also note the frequency of SO2 exposures. Peak exposure is determined by calculating the number of times the 10 minute mean exceeded 500 μg/m3 of SO2 in a calendar year. Long-term exposure is determined by calculating the number of times the daily mean exceeded 20 μg/m3 of SO2 in a calendar year.

　　NOTE If the local air quality monitoring stations measure SO2 in parts per billion the following conversion ratio to μg/m3: 1 ppb = 2.62 μg/m3 shall be used. The conversion assumes an ambient pressure of 1 atmosphere and a temperature of 25 degrees Celsius. The general equation is μg/m3 = (ppb)*(12.187)*(M) / (273.15 + °C) where M is the molecular weight of the gaseous pollutant. An atmospheric pressure of 1 atmosphere is assumed.

　　8.5.3 Data Sources

　　Hourly average concentrations are measured by monitoring equipment and reported to Air Quality monitoring authority (i.e., City Environment Office, National Environment Office, etc.).

　　8.6 O3 (Ozone) concentration

　　8.6.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE: High concentrations of ozone in the ambient air are harmful for humans as well as plants. High concentrations of ozone can irritate the respiratory system and are linked to asthma, bronchitis and heart attacks. The elderly are especially vulnerable. There are links being made to ozone concentration and environmental justice, in particular with reference to underprivileged social groups with higher exposure and vulnerability.

　　8.6.2 Supporting indicator requirements

　　O3(ozone) concentration shall be calculated as the sum of daily concentrations for the whole year (numerator) divided by 365 days (denominator). The result shall be expressed as the annual average for daily O3 (ozone) concentration in µg/m3. O3 is normally monitored at 8- hour intervals. To determine the 24 hour average daily concentration, the three 8 hour concentrations shall be determined and averaged over a 24 hour period at all monitoring stations within the city’s boundaries.

　　NOTE If local stations monitor O3 in parts per billion, the following conversion ratio to μg/m3 shall be used: 1 ppb = 2.00 μg /m3. The conversion assumes an ambient pressure of 1 atmosphere and a temperature of 25 degrees Celsius. The general equation is μg/m3 = (ppb)*(12.187)*(M) / (273.15 + °C) where M is the molecular weight of the gaseous pollutant. An atmospheric pressure of 1 atmosphere is assumed.

　　Long-term exposure shall be determined by the number of days when the daily average concentration over an 8 hour exposure exceeds 100 μg/m3. Long-term exposure shall be noted.

　　8.7 Noise Pollution

　　8.7.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE: Prolonged exposure to noise can lead to significant health effects, both physical and mental.

　　8.7.2 Supporting indicator requirements

　　Noise pollution shall be calculated by mapping the noise level Lden (day-evening-night) likely to cause annoyance as given in ISO 1996-2:1987 , identifying the areas of the city where Lden is greater than 55 dB(A) and estimating the population of those areas as a percentage of the total city population. The result shall be expressed as the percentage of the population affected by noise pollution.

　　The users of this standard should note that noise pollution can also be recorded as Ln (night) and when exceeding 50 dB(A) is likely to cause sleep deprivation.

　　NOTE 1: Another useful indicator of the noise levels in a city is the degree of annoyance as specified in ISO/TS 15666:2003.

　　8.7.3 Data Sources

　　Average concentrations are measured by monitoring equipment and reported to Air Quality monitoring authority (i.e., City Environment Office, National Environment Office, etc.)

　　8.8 Percentage change in number of native species

　　8.8.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Urbanization affects biodiversity through urban sprawl/habitat fragmentation, loss of fertile agricultural lands, and spread of invasive alien species. A loss in biodiversity threatens food supplies, lessens opportunities for recreation and tourism, and impacts a diverse range of medicinal sources, varieties of wood, and energy. It also interferes with essential ecological function, such as carbon sequestration and air filtering. The net change in the number of native species in a municipality is an indication of biological diversity loss or gain.

　　8.8.2 Supporting indicator requirements

　　The percentage change in number of native species shall be calculated as the total net change in species (numerator) divided by the total number of species from the 5 taxonomic groups from most recent survey (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　The net change in species shall be calculated as the number of new species within the city from the three core taxonomic groups and the city’s selection of an additional two taxonomic groups (as a result of re-introduction, rediscovery, new species found, etc.) subtracted by the number of species that have become extirpated or locally extinct within the city.

　　The three core taxonomic groups shall refer to vascular plants, birds and butterflies. Additional taxonomic groups that cities should select can include the following: mammals, insects, bryophytes, fungi, amphibians, reptiles, freshwater fish, molluscs, dragonflies, carabid beetles, spiders, hard corals, marine fish, seagrasses, sponges, etc. A full list can be found in the User’s Manual for the City Biodiversity Index[83].

　　8.8.3 Data sources

　　Possible sources of data include government agencies in charge of biodiversity, city municipalities, urban planning agencies, city forestry departments, biodiversity centres, nature groups, universities, etc.

　　9 Finance

　　9.1.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE Widely accepted as a measure of sound financial management, this indicator reflects the amount of financial resources that are available for day-to-day operations and how much money is spent paying down debt. It can be a controllable cost and can assist in priority setting.

　　9.1.2 Core indicator requirements

　　Debt service ratio is the ratio of debt service expenditures as a per cent of a municipality’s own source revenue. Debt service ratio shall be calculated as the total long-term debt servicing costs including lease payments, temporary financing and other debt charges (numerator) divided by total own source revenue (denominator). The result shall be expressed as a ratio of debt service expenditure as a percent of a municipality’s own-source revenue.

　　Total own source revenue shall be calculated as the total revenue less transfers.

　　9.1.3 Data interpretation

　　A lower number may indicate either an increased ability to borrow or a decision by a municipality to limit its debt to enable funding of other service areas.

　　Care must be used in evaluating this indicator. A high debt service ratio may indicate a municipality that has taken on too much debt but it may also indicate that the municipality has taken an aggressive approach to debt repayment and is paying down their debt quickly. Similarly, a low debt service ratio could indicate a municipality is strong financially and can finance most capital projects through alternative funding sources. It may also indicate that a municipality is financially weaker and has deferred capital projects and allowed important infrastructure to deteriorate.

　　9.2 Capital spending as a percentage of total expenditures

　　9.2.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The amount of capital expenditure by the city expressed as a percentage of the total city expenditure is an indicator of capital re-investment and the fiscal health of the city.

　　9.2.2 Supporting indicator requirements

　　The capital spending as a percentage of total expenditures shall be calculated as the total expenditure on fixed assets in the preceding year (numerator) divided by the total expenditure (operating and capital) by the city in that same period, and shall be expressed as a percentage.

　　NOTE Fixed assets are not expected to be consumed or converted into cash in the normal course of business. They are long-term, more permanent or “fixed” items, such as land, building, equipment, fixtures, furniture, and leasehold improvements.

　　9.2.3 Data sources

　　The figures used in this calculation should to be taken directly from the city’s audited financial statements without amendment or variation.

　　9.2.4

　　Data interpretation

　　This indicator needs to be considered in conjunction with the debt service ratio indicator to obtain an understanding of the city’s capacity to maintain its capital expenditure. The level of capital expenditure in relation to recurrent expenditure may reflect the city’s financial capacity to invest in capital items needed to support future growth and development.

　　9.3 Own-source revenue as a percentage of total revenues

　　9.3.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE On a very basic level, this indicator measures the level of dependence of the city on other levels of government for revenues to deliver its services to the public.

　　9.3.2 Supporting indicator requirements

　　Own-source revenue as a percentage of total revenues shall be calculated as the total amount of funds obtained through permit fees, user charges for city services, and taxes collected for city purposes only (numerator), divided by all operating or re-occurring revenues including those provided by other levels of government transferred to the city (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Own-source revenue as a percentage of total revenues represent the percentage of local government revenues originating from fees, charges and taxes as permitted by law or legislation in relation to all revenues including those provided by other levels of government, (which includes operating or re-occurring revenues determined through methods such as formula driven payments or repatriation of income tax, grant donations from higher government levels including national or state governments and other types of financial transfers that may be tied to the delivery of specific services.

　　9.4 Tax collected as a percentage of tax billed

　　9.4.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Tax collection is a major source of income for all levels of government including cities. This indicator is intended to measure the effectiveness of a city’s financial management capabilities and to some extent is a proxy of the willingness of citizens to pay taxes.

　　9.4.2

　　Supporting indicator requirements

　　The tax collected as a percentage of tax billed measures the ratio of the actual tax collected to the mandated tax. It shall be calculated as the total revenues generated by tax collection (numerator) divided by the amount of taxes billed (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　10 Fire and emergency response

　　10.1Number of firefighters per 100 000 population

　　NOTE Fire response is one of the fundamental services that all cities provide in its role of protecting life and property of its citizens.

　　10.1.2Core indicator requirements

　　The number of firefighters per 100 000 population shall be calculated as the total number of paid full-time firefighters (numerator) divided by one 100 000th of the city population (denominator). The result shall be expressed as the number of firefighters per 100 000 population.

　　A firefighter shall refer to a full-time operational staff member located in the fire suppression unit that regularly responds to daily calls, and shall not include staff from fire prevention, safety, training, administration, senior management not directly involved in fire suppression, communication and dispatch.

　　This indicator is only intended to identify the number of paid fire fighters engaged in fire suppression or directly related activities. This indicator shall not include volunteer firefighters and shall be reported as a separate indicator.

　　NOTE The choice of 100 000 population was chosen to permit cities of different sizes to be able to compare results with each other relatively easily and effectively. It should be noted that in some countries this statistic is typically collected per 1000 capita and a slight mathematical adjustment may be necessary to reflect this difference to obtain an accurate comparison.

　　10.2 Number of fire related deaths per 100 000 population

　　10.2.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE One of the many measures used to demonstrate the effectiveness of a city’s fire services is the number of fire related deaths that occur on an annual basis.

　　10.2.2

　　Core indicator requirements

　　The number of fire related deaths per 100 000 population shall be expressed as the number of deaths directly attributed to a fire incident with death occurring within 30 days. This indicator shall be calculated as the total number of citizen fire related deaths recorded in a 12 month period (numerator), divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of fire related deaths per 100 000 population.

　　NOTE Some of the factors that can influence the rate of fatalities in a city include: Age and density of housing, fire prevention and education efforts, socio-demographics, enforcement of Fire Code, and presence of working smoke detectors and alarm systems [35].

　　10.3 Number of natural disaster –related deaths per 100 000 population

　　10.3.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The attractiveness of cities for citizens and investors alike, is affected by the frequency and magnitude of natural disasters occurring within a city and a city’s ability to respond. The natural disaster- related losses of lives in the past can be indicative of a city’s potential future exposure.

　　10.3.1 Core indicator requirements

　　The number of natural-disaster related deaths per 100 000 population shall be expressed as the number of deaths directly attributed to natural disaster incidents. This indicator shall be calculated as the total number of natural disaster related deaths recorded in a 12 month period (numerator), divided by one 100 000th of the city population (denominator). The result shall be expressed as the number of natural disaster-related deaths per 100 000 population.

　　NOTE As natural disasters are generally not restricted to the exact geographic confines of a city, disaster database content may need slight readjustment / recalculation to produce results matching a given city’s defined geographic boundary.

　　10.3.2 Data sources

　　Insurance companies and disaster management agencies are key providers of such data

　　10.3.3 Data interpretation

　　This indicator can be expanded beyond fatalities. Monetary losses can also be assessed as a result of natural disasters. This data is often available from insurance companies.

　　10.4Number of volunteer and part-time firefighters per 100 000 population

　　10.4.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Fire response is a fundamental service for protecting life and property of citizens. While many larger cities (25 000 or more people) are served by full time firefighters, many communities are also protected by volunteer firefighters. Volunteer firefighters are often located in smaller, rural departments.

　　10.4.2Supporting indicator requirements

　　The number of volunteer and part time firefighters per 100 000 population shall be calculated as the total number of volunteer and part time firefighters (numerator) divided by one 100 000th of city’s total population (denominator).The result shall be expressed as the number of volunteer and part time firefighters per 100 000 population.

　　Volunteer firefighters shall refer to individuals who respond to incidents without pay.

　　Part-time firefighters shall refer to individuals who are not considered full time career firefighters and are paid only for incidents that they respond to.

　　NOTE The term "volunteer" may be used in reference to a group of part-time or on call firefighters who may have other occupations when not engaged in occasional firefighting. Therefore, volunteer and part time firefighters are considered to be the same classification.

　　10.5Response time for emergency response services from initial call

　　10.5.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The average response time (in minutes and seconds) it takes an emergency and rescue department to respond to an initial distress call is an indicator of how protected a city’s residents are from security and safety threats.

　　10.5.2Supporting indicator requirements

　　The response time for the emergency and rescue department from the initial call shall be calculated as the sum of all initial distress calls to the on-site arrival of the emergency personnel and equipment in minutes and seconds for the year (numerator) divided by the number of emergency responses in the same year (denominator). The result shall be expressed as the response time for emergency response services from initial call in minutes and seconds.

　　The total number of minutes and seconds taken to respond to all emergency rescue calls shall include the time elapsed from receiving the initial call for assistance to arrival on-site of emergency personnel and equipment is calculated for the preceding 12 months.

　　NOTE Because it has the appearance of objectivity, emergency response time is a valuable key operational measure used to assess system performance from the citizen’s perspective.

　　10.6Response time for fire department from initial call

　　10.6.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　The total number of minutes and seconds taken to respond to all emergency calls shall include the time elapsed from receiving the initial call for assistance to the on-site arrival of fire department personnel and equipment and is calculated for the preceding 12 months.

　　NOTE Because it has the appearance of objectivity, response time is a valuable and key operational measure used to assess system performance from the citizen’s perspective

　　11 Governance

　　11.1 Voter participation in last municipal election (as a percentage of eligible voters)

　　11.1.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The percentage of the eligible voting population that voted in the last municipal election is an indicator of the public’s level of participation and degree of interest in local government.

　　11.1.2 Core indicator requirements

　　The voter participation in the last municipal election shall be calculated as the number of persons that voted in the last municipal election (numerator) divided by the city population eligible to vote (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　A result of zero shall be indicated if there have been no municipal elections in the last five years and this shall be noted in the comments.

　　In countries where voting is mandatory, the per cent of votes (ballots) that are not blank or spoiled shall be reported. This will indicate the share of positive voter participation.

　　There is a distinction between eligible to vote and registered to vote. In some countries people have to register (actively) in order to be allowed to vote. In all other countries, eligible and registered voters are one and the same. This should be noted.

　　11.1.3 Data sources

　　Information should be obtained from the local authorities, officials or the Ministry responsible for local governments.

　　11.1.4

　　Data interpretation

　　This indicator will only reveal the level of participation, not the level of satisfaction of the population. In some cases, high rates of participation will mean that the population is not satisfied with its local government’s leadership and actions.

　　11.2 Women as a percentage of total elected to city-level office

　　11.2.1 General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The percentage of women elected to city-level office is a direct reflection of inclusiveness in governance.

　　11.2.2 Core indicator requirements

　　The number of women elected to city-level office shall be calculated as the total number of elected city-level positions held by women (numerator) divided by the total number of elected city-level positions (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　11.3 Percentage of women employed in the city government workforce

　　11.3.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The percentage of the city government workforce that is women is a direct reflection of the equity of the hiring system within the city government.

　　11.3.2Supporting indicator requirements

　　The number of women employed in the city government workforce shall be calculated as the total number of employees in the city government workforce that are women (numerator) divided by the total number of the city government workforce (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　The city government workforce shall be calculated as the total number of employees working within the city government.

　　11.4 Number of convictions for corruption/bribery by city officials per 100 000 population

　　11.4.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements

　　NOTE The principles of governance include selflessness, objectivity, accountability, openness, honesty and leadership. The number of convictions for corruption/bribery can reflect the extent to which governance adheres to these core principles.

　　11.4.2 Supporting indicator requirements

　　The number of convictions for corruption and/or bribery by city officials shall be calculated as the total number of convictions for corruption and/or bribery by city officials (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of convictions for corruption and/or bribery by city officials per 100 000 population.

　　City officials are the elected or employed representatives of the city.

　　11.5 Citizens’ representation: number of local officials elected to office per 100 000 population

　　11.5.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The number of public officials elected by citizens of the city and the right of citizens as guaranteed by law, to examine and then make submissions/objections to urban planning, development and infrastructure policies/plans/projects prior to their approval/construction is an indicator of citizens’ rights to participate in the affairs of their city.

　　11.5.2 Supporting indicator requirements

　　The number of local officials elected to office per 100 000 shall be calculated as the total number of public officials elected to local office by citizens of the city (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of local officials elected to office per 100 000 population.

　　The term “public officials elected to local office by citizens of the city” shall include all positions in the public service relating to the city that require election by the citizens of the city to hold office. It includes all councils, boards, commissions etc. where members are elected by the citizens of the city but does not include national or state government politicians.

　　NOTE This indicator only reveals the number of local officials elected to office and does not determine whether or not citizens have the right, guaranteed by law, to examine and then make submissions/objections to urban planning, development and infrastructure policies/plans/projects prior to their approval/construction. It is codified and enforceable law of the city that guarantees citizens the right to examine and then make submissions/objections to urban planning, development and infrastructure

　　policies/plans/projects prior to their approval/construction in order for cities to report that this element of the citizens’ participation exists in their city. Whether these rights exist should be noted.

　　11.5.3 Comments and limitations

　　An increase in elected city officials and a corresponding increase in city workers may in some circumstances indicate an expensive city administration.

　　11.6 Number of registered voters as a percentage of the voting age population

　　11.6.1

　　General

　　This is a supporting indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE Determining the percentage of the number of registered voters from the voting age population can reveal the legitimacy and quality of the electoral process in a city. For citizens to exercise their democratic right to vote there must be a comprehensive and inclusive electoral register, also called a voters list; and this must be carefully maintained to ensure that each eligible citizen is registered to vote once and only once. A voters list makes it possible to separate two of the most important functions of the election authority: verifying voter eligibility and controlling the legitimacy of the balloting process.

　　11.6.2 Supporting indicator requirement

　　The number of registered voters as a percentage of the voting age population shall be calculated as the total number of registered voters, as determined by the official voter register (numerator) divided by the voting age population (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Number of registered voters shall refer to the number of names on the voters’ register at the time that the registration process closes (cut-off date), as reported by the election authority. The election authority should use one of three options for voter registration: a periodic list, a continuous register/ list, or a civil registry. Any one of these options can determine the number of registered voters.

　　Voting age population shall include all citizens of legal voting age.

　　NOTE Voting age population is not neccessarily an exact measure of the number of citizens entitled to vote as it does not take into account legal or systemic barriers to the exercise of the franchise or account for non- eligible members of the population, such as resident non-citizens or in some jurisdictions persons serving a sentence of imprisonment in a penal or correctional institution (the voting eligible population – VEP – would capture these discrepancies but it is very hard to achieve the data required to measure VEP). However in some countries, non-citizens, such as immigrants have been granted the legal right to vote in municipal elections before they become citizens.

　　12 Health

　　12.1Average life expectancy

　　12.1.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE Life expectancy reflects the overall mortality level of a population. Life expectancy is closely connected with health conditions, which are an integral part of development. Mortality is also one of the variables that determine the size of human populations and their potential for future growth. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures.

　　12.1.2Core indicator requirements

　　The average life expectancy shall be calculated as the average number of years to be lived by a group of people born in the same year, if health and living conditions at the time of their birth remained the same throughout their lives [3][84].

　　12.2 Number of in-patient hospital beds per 100 000 population

　　12.2.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The number of in-patient public hospital beds is one of the few available indicators which monitor the level of a health service delivery. Service delivery is an important part of health systems, and in-patient public hospital bed density is one of the few indicators that can be collected worldwide (WHO, 2006)[12].

　　12.2.2 Core indicator requirements

　　The number of in-patient hospital beds per 100 000 shall be calculated as the total number of in- patient public and private hospital beds (numerator), divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of in-patient public and private hospital beds per 100 000 of the city population.

　　Hospital beds shall include in-patient and maternity beds. This shall include beds in wards which are closed for reasons such as lack of health staff, and building works. It shall also include beds for patients admitted who require continual assistance, incubators and specialized care. It may not include day care beds, pre-anaesthesia beds, wake-up beds, beds for members of a patient’s family, and beds for hospital staff [6].

　　12.2.3 Data sources

　　This indicator should rely on administrative records, based on reported data by public inpatient facilities. Data may also come from censuses of health care facilities.

　　12.3 Number of physicians per 100 000 population

　　12.3.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The availability of physicians is an important indicator of the strength of a city’s health system. There is evidence that the number of physicians is positively associated with immunization coverage, outreach of primary care, and infant, child and maternal survival (WHO, 2006)[12].

　　12.3.2 Core indicator requirements

　　The number of physicians per 100 000 population shall be calculated as the number of general or specialized practitioners whose work-place is in the city (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of physicians per 100 000 population.

　　For this indicator, a physician shall be defined as someone who graduates from any facility or school of medicine whose work-place is in the city.

　　FTE shall be applied, in order to capture doctors working part-time in hospitals and in practices.

　　12.3.3 Data sources

　　Cities should report the number of physicians based on administrative records such as registered physicians in the City. Information may also be obtained from the census, labour force statistics or other surveys which inquire about occupation.

　　The accuracy and completeness of the human resource data in countries can be a problem because databases are not updated frequently, private sector data are often not included and definitions of workers vary. It is for this reason that yearly updated data sources, such as administrative records, should be used. The definition presented above shall be the definition used when gathering data to report on this indicator.

　　12.4 Under age five mortality per 1 000 live births

　　12.4.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The under age five mortality rate is a leading indicator of the level of child health and overall development in cities. Child mortality is an indicator of the status of the City as a healthy or unhealthy place to live. In addition, mortality rates are among the most frequently used indicators to compare levels of socioeconomic development across countries. Improving child mortality rates is a vital component of the Millennium Development Goals[21].

　　12.4.1 Core indicator requirements

　　The under age five mortality per 1 000 live births shall refer to the probability of a child born in a specified year dying before reaching the age of five, and shall be expressed as a rate per 1 000 live births.

　　NOTE The under age five mortality rate, is strictly speaking, not a rate (i.e. the number of deaths divided by the number of population at risk during a certain period of time) but a probability of death derived from a life table and expressed as rate per 1 000 live births.

　　Age-specific mortality rates among children and infants shall be calculated from birth and death data derived from vital registration, census, and/or household surveys. Estimates based on household surveys data shall be obtained:

　　a) directly, using birth history, as in demographic and health surveys, or

　　b) indirectly, using the Brass method, as specified in the Multiple Indicator Cluster Surveys[26].

　　The data shall then be summed for children under age five and shall be expressed as a rate per 1,000.

　　12.4.2 Data sources

　　At the city level, a complete vital statistics registration system covering at least 90 per cent of vital events in the population should be used, since these represent the best source of data. Such systems are uncommon in developing countries, so estimates may be obtained from sample surveys or derived by applying direct and indirect estimation techniques to registration, census or survey data.

　　NOTE In developing countries, household surveys are essential to the calculation of this indicator, but there are some limits to their quality. Survey data are subject to recall error, and surveys estimating under age five deaths require large samples, because such incidences are uncommon and representative households cannot ordinarily be identified by the sampling. Moreover, the frequency of the survey is generally only every three to five years. When using household surveys the user shall take sampling errors into account. Also, indirect estimates rely on estimated actuarial (“life”) tables that may be inappropriate for the population concerned.

　　12.5Number of nursing and midwifery personnel per 100 000 population

　　12.5.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The number of nursing and midwifery personnel is a good indication of the city’s health system and the strength of its outreach for maternal health.

　　12.5.2Supporting indicator requirements

　　The number of nursing and midwifery personnel shall be calculated as the total number of nurses and midwives (numerator), divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of nursing and midwifery personnel per 100 000 population.

　　The number of nurses shall include actively practicing nurses and midwives employed in public and private hospitals, clinics and other health facilities, including self-employed nurses and midwives. Both fully-qualified nurses with post-secondary education in nursing and vocational/associate/auxiliary/practical nurses with a lower level of nursing skills but also usually registered, shall be reported.

　　NOTE Some figures may be underestimated or overestimated when it is not possible to distinguish whether the data includes health workers in the private sector, double counts of health workers holding two or more jobs at different locations, health service providers working outside the health care sector (e.g. nurses working in a school or large private company), workers who are unpaid or unregulated but performing health care tasks (e.g. volunteer community health workers) or people with health vocational training who are not currently engaged in the national health labour market (e.g. unemployed, migrated, retired or withdrawn from the labour force for personal reasons).

　　12.6 Number of mental health practitioners per 100 000 population

　　12.6.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Mental health is central to human development. Positive mental health is linked to a range of development outcomes, including better health status, higher educational achievement, enhanced productivity and earnings, improved interpersonal relationships, better parenting, closer social connections and improved quality of life. Positive mental health is also fundamental to coping with adversity.

　　On the other hand, poor mental health impedes an individual’s capacity to realize their potential, work productively, and make a contribution to their community. The social and economic impact of mental and psychosocial disabilities is diverse and far-reaching, leading to homelessness, poor educational and health outcomes and high unemployment rates culminating in high rates of poverty. All these issues are directly linked to the Millennium Development Goals (MDGs).

　　12.6.2 Supporting indicator requirement

　　The number of mental health practitioners per 100 000 population shall be calculated as the total number of mental health practitioners whose work-place is in the city (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of mental health practitioners per 100 000 population.

　　Mental health practitioners shall refer to psychiatrists, clinical psychologists, clinical social workers, psychiatric nurses and mental health counsellors.

　　12.7 Suicide rate per 100 000 population

　　12.7.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Suicide rate is a serious issue in many cities and reflects on mental health in a city which is central to human development.

　　12.7.2 Supporting indicator requirements

　　The number of deaths by suicide per 100 000 population shall be calculated as the total number of reported deaths by suicide (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of deaths by suicide per 100 000 population.

　　Death by suicide shall refer to acts deliberately initiated and performed by a person who fully acknowledges the fatal outcome of such acts.

　　12.7.3 Data sources

　　This information should be obtained from the coroner’s office, regional health authority or national census.

　　NOTE Suicides are not always reported as such. In particular, suicides may sometimes be reported as homicides or accidents.

　　13 Recreation

　　13.1 Square meters of public indoor recreation space per capita

　　13.1.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Recreation is an important aspect of city life, contributing to the health of citizens and the vitality of the city. Recreation is a service that many cities provide through a parks and recreation department or related office.

　　13.1.2 Supporting indicator requirements

　　Square meters of public indoor recreation space per capita shall be calculated as the square meters of indoor public recreation space (numerator) divided by the population of the city (denominator), and shall be expressed as the number of square meters of indoor recreation space per capita.

　　Note: The need for indoor public recreational spaces varies depending on local climatic and cultural conditions.

　　Public recreation space is defined broadly to mean land and buildings open to the public for recreation. Recreation space shall include only space that primarily serves a recreation purpose.

　　Indoor public recreation space should include:

　　a) city-owned or maintained buildings;

　　b) other recreation buildings within the city not owned or operated by the city, provided they are open to the public. This category may include state or provincially owned buildings, schools and colleges, as well as non-profit. If cities report only city-owned recreation space, this shall be noted.

　　For multi-story buildings the floor area of all floors in the building should be counted if known.

　　For multi-use facilities only the portion of the building devoted to recreation shall be counted (the play areas at a school or college, for example, not the entire school site).

　　The area of the entire recreation site shall be included (including, for example, building maintenance and utility areas) but shall exclude parking areas.

　　NOTE Many cities report city-owned recreation space and this does not include the contribution to recreation from non-city-owned facilities. This may be very important in developing countries. While the methodology in this International Standard is more complex, the result will ultimately be more meaningful. It is recommended that a recreation space inventory be created.

　　13.1.3 Data sources

　　This information should be obtained from the City Planning Department together with departments knowledgeable about the city.

　　Recreation spaces may also be delineated using aerial photography and/or land use maps. Once the areas have been identified on a map, the area in square meters may be calculated using low cost Geographic Information Systems (GIS) or, if not available, through use of hand-held measuring devices. Area may be calculated in hectares or acres and converted to square meters.

　　13.2

　　Square meters of public outdoor recreation space per capita

　　Public recreation space is defined broadly to mean land and open space available to the public for recreation. Recreation space shall include only space that primarily serves a recreation purpose.

　　Outdoor recreation space should include:

　　a) city-owned or maintained land;

　　b) other-recreation lands within the city not owned or operated by the city, provided they are open to the public. This category may include state or provincially owned lands, school and college grounds, as well as non-profit. If cities report only city-owned recreation space, this shall be noted.

　　For multi-use facilities, only the portion of the land devoted to recreation shall be counted (the play areas at a school or college, for example, not the entire school site). Double counting shall be avoided. For example, do not include indoor facilities on parkland.

　　The area of the entire outdoor recreation site shall be included (including, for example wooded areas of parks, building maintenance and utility areas) but shall exclude parking areas.

　　NOTE Many cities report city-owned recreation space and this does not include the contribution to recreation from non-city owned facilities. This may be very important in developing countries. While the methodology in this International Standard is more complex, the result will ultimately be more meaningful. It is recommended that a recreation space inventory be created.

　　13.2.3 Data sources

　　This information should be obtained from a City Planning Department together with departments knowledgeable about the city.

　　Outdoor recreation spaces may also be delineated using aerial photography and/or land use maps. Once the areas have been identified on a map, the area in square meters may be calculated using low cost Geographic Information Systems (GIS) or, if not available, through use of hand-held measuring devices. Area may be calculated in hectares or acres and converted to square meters.

　　14 Safety

　　14.1 Number of police officers per 100 000 population

　　14.1.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The number of sworn police officers per 100 000 population is an indicator of the overall crime prevention in place in a city.

　　14.1.2 Core indicator requirements

　　The number of police officers per 100 000 population shall be calculated as the number of permanent full-time (or full-time equivalent) sworn police officers (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of police officers per 100 000 population.

　　Sworn law enforcement officers should meet the following criteria: work in an official capacity; have full arrest powers; carry identification; and, be paid from governmental funds set aside specifically for payment of sworn law enforcement representatives.

　　Each year, law enforcement agencies shall report the total number of sworn law enforcement officers as of a locally determined date. Personnel counts shall be based on permanent, FTE. Part- time employees can be converted to full-time equivalents (e.g. four employees working 10 h per week would equal one full-time employee working a 40 h week). Temporary officers shall not be included in this count.

　　14.1.3 Data sources

　　Data for this indicator should be gathered through police personnel information collected annually.

　　14.2 Number of homicides per 100 000 population

　　14.2.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The number of homicides is an indicator of the amount of crime and an indicator of feelings of personal safety and can affect incentives to invest.

　　14.2.2 Core indicator requirements

　　The number of homicide per 100 000 population shall be calculated as the number of reported homicides (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of homicides per 100 000 population.

　　Homicide shall include intentional and non-intentional homicide. Intentional homicide shall refer to death deliberately inflicted on a person by another person, including infanticide.

This shall include manslaughter, but shall exclude traffic accidents that result in the death of a person, and suicides.

　　14.2.3 Data sources

　　The data should be obtained from the police or other law enforcement agencies.

　　NOTE Homicides are not always reported as such. In particular, domestic homicides are sometimes reported as suicides or accidents.

　　14.3Crimes against property per 100 000

　　14.3.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The number of property crimes is an indicator of the amount of criminal offences against privately- owned property and an indicator of feelings of personal safety and can affect incentives to invest. The number of property crimes in a city is considered a benchmark for the overall level of safety in the city. Because they have the appearance of objectivity, property crime statistics are a valuable key operational measure used to assess system performance concerning private space protection from the citizen’s perspective.

　　14.3.2Supporting indicator requirements

　　The number of crimes against property shall be calculated as the total number of all property crimes reported (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of property crimes per 100 000 population.

　　Crimes against property shall be defined as all offences involving the unlawful taking or destruction of property, but without the threat of use of force against a person.

　　Crime against property should include: burglary; larceny-theft; motor vehicle theft; and, arson.

　　14.4Response time for police department from initial call

　　14.4.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The average response time (in minutes and seconds) it takes a police department to respond to an initial distress call is an indicator of how protected a city’s residents are from security and safety threats. Because it has the appearance of objectivity, police response time is a valuable and key operational measure used to assess system performance from the citizen’s perspective.

　　14.4.2Supporting indicator requirements

　　The response time for police department from initial call shall be calculated as the sum of number of all initial distress calls to the on-site arrival of the police department personnel for the year in minutes and seconds (numerator) divided by the number of police department responses in the same year (denominator). The result shall be expressed as the response time for police department from initial call in minutes and seconds.

　　The total number of minutes and seconds taken to respond to all emergency calls shall include the time elapsed from receiving the initial call for assistance to arrival on-site of police department personnel is calculated for the preceding 12 months.

　　14.5Violent crime rate per 100 000 population

　　14.5.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The number of violent crimes is an indicator of the amount of serious criminal offences in a City and a lead indicator of feelings of personal safety. The number of violent crimes in a city is considered a benchmark measure of the overall level of safety in the city.

　　14.5.2Supporting indicator requirements

　　The violent crime rate per 100 000 population shall be calculated as the total number of all violent crimes reported (numerator) divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of violent crimes per 100 000 population.

　　Violent crimes shall include offences that involve force or the threat of force to a person. Total violent crimes reported shall be calculated as the total sum of the number of murders and non- negligent manslaughters, the number of rapes, the number of robberies and the number of aggravated assaults.

　　Furthermore, a violent crime should be classified as one of the following four offences (in order of severity): murder and non-negligent manslaughter; rape; robbery; and, aggravated assault.

　　For a multiple-offence, only the most serious/severe offence shall be counted.

　　15 Shelter

　　15.1 Percentage of city population living in slums

　　15.1.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The percentage of the population living in slums is an indicator of the number of city residents living in substandard or insecure housing. Evidence shows that slums are growing and becoming permanent features of urban landscapes. One out of every three city dwellers lives in a slum today. Since slums host significantly large proportions of the urban population it is important to measure them.

　　15.1.2 Core indicator requirements

　　The percentage of city population living in slums shall be calculated as the number of people living in slums (numerator) divided by the city population (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　The number of people living in slums shall be calculated as the number of slum households multiplied by current average household size.

　　Different cultures and countries define the physical and social attributes of slums differently. UN- HABITAT acknowledges this diversity and the fact that slums take many different forms and names.

　　A slum household shall refer to a group of individuals living under the same roof in an urban area who lack one or more of the following five conditions:

　　a) Durable housing: A house is considered “durable” if it is built on a non-hazardous location and has a structure permanent and adequate enough to protect its inhabitants from the extremes of climatic conditions, such as rain, heat, cold and humidity.

　　b) Sufficient living area: A house is considered to provide a sufficient living area for the household members if not more than three people share the same room.

　　c) Access to improved water: A household is considered to have access to improved water supply if it has a sufficient amount of water for family use, at an affordable price, available to household members without being subject to extreme effort, especially on the part of women and children.

　　d) Access to sanitation: a household is considered to have adequate access to sanitation if an excreta disposal system, either in the form of a private toilet or a public toilet shared with a reasonable number of people, is available to household members.

　　e) Secure tenure: Secure tenure is the right of all individuals and groups to effective protection against forced evictions. People have secure tenure when there is evidence of documentation that can be used as proof of secure tenure status or when there is either de facto or perceived protection against forced evictions.

　　Care should be taken to avoid double counting so as to not exaggerate or over-count the percentage of population in slums.

　　EXAMPLE A household that lacks access to improved water and does not have secured tenure should be counted as one slum household.

　　15.1.3 Data sources

　　Data for the above conditions should be gathered from census and survey data and information from agencies working with slums.

　　15.2 Number of homeless per 100 000 population

　　15.2.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Having a home to live in can be considered a basic need. There may be several reasons for a homeless situation, such as the housing price to income ratio[40].

　　15.2.2 Supporting indicator requirements

　　The number of homeless per 100 000 population shall be calculated as the total number of homeless people (numerator), divided by one 100 000th of the city’s total population (denominator). The result shall be expressed as the number of homeless per 100 000 population.

　　The following definition is used by the United Nations[41] to define homelessness: Absolute homelessness refers to those without any physical shelter, for example, those living outside, in parks, in doorways, in parked vehicles, or parking garages, as well as those in emergency shelters or in transition houses for women fleeing abuse.

　　15.3 Percentage of households that exist without registered legal titles

　　15.3.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　15.3.1 Supporting indicator requirements

　　The percentage of households that exist without registered legal titles shall be calculated as the number of households that exist without registered legal titles (numerator) divided by the total number of households (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Unregistered legal title includes the following tenure types: unregistered lease or leaseholds, rental, occupancy right, use right (including sub-lease, sub-rental and co-tenancy, and co-occupancy right).

　　16 Solid waste

　　16.1 Percentage of city population with regular solid waste collection (residential)

　　16.1.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE The percentage of the city population served by regular solid waste collection is an indicator of city health, cleanliness and quality of life. Solid waste systems contribute in many ways to public health, the local economy, the environment, and the social understanding and education about the latter.

　　16.1.2 Core indicator requirements

　　The percentage of city population with regular solid waste collection shall be calculated as the number of people within the city that are served by solid waste collection (numerator) divided by the total city population (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　The number of households in the city serviced with regular solid waste collection shall first be determined. The number of households being serviced by the regular solid waste collection service shall then be multiplied by the current average household size for that city to determine the number of persons serviced with regular solid waste collection. Regular solid waste collection shall be defined as having the solid waste picked up from the household, transported and dropped at a proper treatment facility (recycling or landfill sites) on at least a weekly basis or every two weeks. If the solid waste is collected in any moving vehicle by persons that have not constituted a legally established entity, the house shall not be considered as a household serviced with a solid waste collection service.

　　NOTE Use of persons rather than city area as the metric for this indicator avoids the distortion arising from local government areas that include both urban and non-urban areas.

　　16.1.3 Data sources

　　Information should be obtained from the local operator(s) of solid waste collection systems, census data, and municipal waste facilities.

　　16.1.4 Data interpretation

　　Results will only indicate how much of the city population has access to solid waste collection systems, not the quality of the system: the quality of the service (street level), the levels of recycling (and of land fill misuse), or the capacity of the land fill to meet the demand. Some of these issues will be addressed in the supporting indicators.

　　The proper discharge, transportation and treatment of solid waste is one of the most important components of life in a city and one of the first areas in which governments and institutions should focus. Solid waste systems contribute in many ways to public health, the local economy, the environment, and the social understanding and education about the latter. A proper solid waste system can foster recycling practices that maximize the life cycle of landfills and create recycling micro-economies; and it provides alternative sources of energy that help reduce the consumption of electricity and/or petroleum based fuels.

　　16.2 Total collected municipal solid waste per capita

　　16.2.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE This indicator provides a measure of how much waste a city is producing and the level of service a city is providing for its collection. Higher levels of municipal waste contribute to greater environmental problems and therefore levels of collection, and also methods of disposal, of municipal solid waste are an important component of municipal environmental management. Collection of municipal solid waste is also an indicator of city management with regard to cleanliness, health and quality of life. Solid waste systems contribute in many ways to public health, the local economy, the environment, and the social understanding and education about the latter.

　　16.2.2 Core indicator requirements

　　The total collected municipal solid waste per capita shall be expressed as the total municipal solid waste produced in the municipality per person. This indicator shall be calculated as the total amount of solid waste (household and commercial) generated in tonnes (numerator) divided by the total city population (denominator). The result shall be expressed as total municipal solid waste collected per capita in tonnes.

　　Municipal waste shall refer to waste collected by or on behalf of municipalities.

　　The data shall only refer to the waste flows managed under the responsibility of the local administration including waste collected on behalf of the local authority by private companies or regional associations founded for that purpose.

　　Municipal waste should include waste originating from:

　　— households;

　　— commerce and trade, small businesses, office buildings and institutions (e.g. schools, hospitals, government buildings).

　　The definition should also include:

　　— bulky waste (e.g. white goods, old furniture, mattresses);

　　— garden waste, leaves, grass clippings, street sweepings, the content of litter containers, and market cleansing waste, if managed as waste;

　　— waste from selected municipal services, i.e. waste from park and garden maintenance, waste from street cleaning services (e.g. street sweepings, the content of litter containers, market cleansing waste), if managed as waste.

　　The definition shall exclude:

　　— waste from municipal sewage network and treatment;

　　— municipal construction and demolition waste.

　　16.2.3 Data interpretation

　　The proper discharge, transportation and treatment of solid waste is one of the most important components of life in a city and one of the first areas in which governments and institutions should focus. Solid waste systems contribute in many ways to public health, the local economy, the environment, and the social understanding and education about the latter. A proper solid waste system can foster recycling practices that maximize the life cycle of landfills and create recycling micro-economies; and it provides alternative sources of energy that help reduce the consumption of electricity and/or petroleum based fuels.

　　16.3 Percentage of city's solid waste that is recycled

　　16.3.1General

　　This is a core indicator. Those implementing this International Standard shall report on this indicator in accordance with the following requirements.

　　NOTE Many cities generate more solid waste than they can dispose of. Even when municipal budgets are adequate for collection, the safe disposal of collected waste often remains a problem. Diverting recyclable materials from the waste stream is one strategy for addressing this municipal issue. Higher levels of municipal waste contribute to greater environmental problems and therefore levels of collection, and also methods of disposal, of municipal solid waste are an important component of municipal environmental management. Solid waste systems contribute in many ways to public health, the local economy, the environment, and the social understanding and education about the latter. A proper solid waste system can foster recycling practices that maximize the life cycle of landfills and create recycling micro-economies; and it provides alternative sources of energy that help reduce the consumption of electricity and/or petroleum based fuels.

　　16.3.2 Core indicator requirements

　　The percentage of city's solid waste that is recycled shall be calculated as the total amount of the city’s solid waste that is recycled in tonnes (numerator) divided by the total amount of solid waste produced in the city in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Recycled materials shall denote those materials diverted from the waste stream, recovered, and processed into new products following local government permits and regulations (International Solid Waste Association, ISWA[23]).

　　Hazardous waste that is produced in the city and is recycled shall be reported separately.

　　16.3.3 Data sources

　　This information should be obtained from municipal bodies, public services and major private contractors dealing with solid waste collection and disposal. Data may be obtained from specific studies carried out on solid waste for specific projects.

　　Information on selected disposal methods should be gathered from municipal facilities and operators, parastatal and private companies dealing with solid waste treatment. Solid waste experts, as well as NGOs working in this area, may be consulted.

　　16.4 Percentage of the city's solid waste that is disposed of in a sanitary landfill

　　16.4.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Many cities generate more solid waste than they can dispose of. Even when municipal budgets are adequate for collection, the safe disposal of collected waste often remains a problem. Open dumping and unsanitary landfills are sometimes the main disposal methods, particularly in lower income cities; sanitary landfills are the norm in only a limited number of cities worldwide.

　　16.4.1 Supporting indicator requirements

　　The percentage of the city's solid waste that is disposed of in a sanitary landfill shall be calculated as the amount of the city’s solid waste that is disposed of in a sanitary landfill in tonnes (numerator) divided by the total amount of solid waste produced in the city in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Sanitary landfill shall refer to a carefully designed structure which uses a clay liner or a synthetic liner in order to isolate solid waste from the surrounding environment. This isolation is accomplished with a bottom liner and daily covering of soil.

　　16.4.2 Data sources

　　This information should be obtained from municipal bodies, public services and major private contractors dealing with solid waste collection and disposal. Data may be obtained from specific studies carried out on solid waste for specific projects.

　　Information on selected disposal methods should be gathered from municipal facilities and operators, parastatal and private companies dealing with solid waste treatment. Solid waste experts, as well as NGOs working in this area, may be consulted.

　　When data are not available, an estimate of the proportion of waste to sanitary landfill and the proportion disposed to open dump should be provided.

　　16.5 Percentage of the city's solid waste that is disposed of in an incinerator

　　16.5.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Many cities generate more solid waste than they can dispose of. Even when municipal budgets are adequate for collection, the safe disposal of collected waste often remains a problem. As sanitary landfill sites are limited, cities examine other alternatives for disposal such as incineration.

　　16.5.2 Supporting indicator requirements

　　The percentage of the city's solid waste that is disposed of in an incinerator shall be calculated as the total amount of the city’s solid waste that is disposed of in an incinerator in tonnes (numerator)

　　divided by the total amount of solid waste produced in the city in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　An incinerator shall refer to a unit or facility used to burn waste, often referred to as an incineration plant.

　　16.5.3 Data sources

　　This information should be obtained from municipal bodies, public services and major private contractors dealing with solid waste collection and disposal. Data may be obtained from specific studies carried out on solid waste for specific projects.

　　Information on selected disposal methods should be gathered from municipal facilities and operators, parastatal and private companies dealing with solid waste treatment. Solid waste experts, as well as NGOs working in this area, may be consulted.

　　When data are not available, an estimate of the proportion of waste to sanitary landfill and the proportion disposed to open dump should be provided.

　　16.6 Percentage of the city's solid waste that is burned openly

　　16.6.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Many cities generate more solid waste than they can dispose of. Even when municipal budgets are adequate for collection, the safe disposal of collected waste often remains a problem. Open burning as a disposal method remains an alternative for some cities facing budgetary limitations, particularly in lower income cities.

　　16.6.2 Supporting indicator requirements

　　The percentage of the city's solid waste that is burned openly shall be calculated as the amount of the city’s solid waste that is burned in tonnes (numerator) divided by the total amount of solid waste produced in the city in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Burned openly shall refer to the combustion of solid waste in an open dump or open space.

　　16.6.3 Data sources

　　This information should be obtained from municipal bodies, public services and major private contractors dealing with solid waste collection and disposal. Data may be obtained from specific studies carried out on solid waste for specific projects.

　　Information on selected disposal methods should be gathered from municipal facilities and operators, parastatal and private companies dealing with solid waste treatment. Solid waste experts, as well as NGOs working in this area, may be consulted.

　　When data are not available, an estimate of the proportion of waste to sanitary landfill and the proportion disposed to open dump should be provided.

　　16.7 Percentage of the city's solid waste that is disposed of in an open dump

　　16.7.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

Open dump as a disposal method remains an alternative for some cities facing budgetary limitations, particularly in lower income cities.

　　16.7.2 Supporting indicator requirements

　　The percentage of the city's solid waste that is disposed of in an open dump shall be calculated as the amount of the city’s solid waste that is disposed of in an open dump in tonnes (numerator) divided by the total amount of solid waste produced in the city in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Open dump shall refer to an uncovered space or hole where solid waste is disposed of without further treatment.

　　16.7.3 Data sources

　　This information should be obtained from municipal bodies, public services and major private contractors dealing with solid waste collection and disposal. Data may be obtained from specific studies carried out on solid waste for specific projects.

　　Information on selected disposal methods should be gathered from municipal facilities and operators, parastatal and private companies dealing with solid waste treatment. Solid waste experts, as well as NGOs working in this area, may be consulted.

　　When data are not available, an estimate of the proportion of waste to sanitary landfill and the proportion disposed to open dump shall be provided.

　　16.8 Percentage of the city's solid waste that is disposed of by other means

　　16.8.1General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE Many cities generate more solid waste than they can dispose of. Even when municipal budgets are adequate for collection, the safe disposal of collected waste often remains a problem.

　　16.8.2 Supporting indicator requirements

　　The percentage of the city's solid waste that is disposed of by other means shall be calculated as the total amount of the city’s solid waste that is disposed of by other means in tonnes (numerator) divided by the total amount of solid waste produced in the city in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Other means shall refer to methods of disposal by means other than the ones indicated in 16.3 (recycling), 16.4 (sanitary landfill), 16.5 (incinerator), 16.6 (burned openly), and 16.7 (open dump).

　　Information on selected disposal methods should be gathered from municipal facilities and operators, parastatal and private companies dealing with solid waste treatment. Solid waste experts, as well as NGOs working in this area, may be consulted.

　　When data are not available, an estimate of the proportion of waste to sanitary landfill and the proportion disposed to open dump should be provided.

　　16.9 Hazardous Waste Generation per capita (tonnes)

　　16.9.1 General

　　This is a supporting indicator. Those implementing this International Standard should report on this indicator in accordance with the following requirements.

　　NOTE The amount of hazardous waste generated is an indication of the risk to human health and the environment from hazardous substances. Hazardous waste impacts human health and degrades the environment. Hazardous waste may represent an immediate danger, such as burning skin on contact, or longer-term human health or environmental risks due to accumulation and persistence of toxics in the environment. Since many hazardous substances are persistent, breaking down very slowly in the environment, they build up in the air, water, food and soil. If disposed of without proper treatment, hazardous wastes can cause serious, long-lasting damage to both terrestrial and aquatic ecosystems. This may lead to habitat fragmentation and the disruption of ecosystem functioning, which in turn may lead to species loss and the decreased ability of ecosystems to support human livelihoods and commercial activities.

　　16.9.2 Supporting indicator requirements

　　The hazardous waste generation per capita shall be calculated as the annual total amount of hazardous waste in tonnes (numerator) divided by total city population (denominator). The result shall be expressed as total hazardous waste generated per capita in tonnes.

　　Hazardous waste generated in the city includes hazardous waste collected under national or municipal hazardous waste directives or regulations, and in accordance with the city’s monitoring and information systems. Hazardous waste is usually accepted at landfills, hazardous waste treatment facilities (including incinerators) and wastewater treatment facilities located in the boundaries of the city. This indicator also covers those hazardous wastes exported for disposal.

　　NOTE Normally the industrial sector is the biggest producer of hazardous waste and they are responsible for adequate disposal and recycling of their waste. However, private households also produce hazardous waste which should be collected separately for adequate disposal and recycling. The Municipality should inform citizens on the negative impacts of this type of waste on the environment and encourage them to use the different collection methods (e.g. separate collection or dedicated collection points).

　　Hazardous Waste shall refer to any substance intended for disposal, which can be harmful to people, plants, animals or the environment. A waste shall be defined as hazardous if it shows one or more of the following characteristics: toxicity, flammability, corrosivity or reactivity. They can be in any form - liquids, solids, gases (in containers), or sludge and are produced by manufacturing processes, the chemical industry, the petroleum industry and other industrial sectors. Examples include acids, alkilis, solvents, medical waste, resins, sludge and heavy metals.

　　Hazardous wastes are those substances that require special technologically advanced methods of disposal to render them harmless or less dangerous to humans and the environment. Hazardous waste must be treated, stored, and disposed of properly at designated sites. Most hazardous wastes are eventually disposed in landfills, surface impoundments (which eventually become landfills), land application units, or by deep well injection.

　　16.9.3 Data Sources

　　Municipal hazardous waste landfill sites; provincial or state authorities that regulate the operations of local facilities; census data.

　　16.10 Percentage of the city’s hazardous waste that is recycled

　　• conserve and protect scarce natural resources,

　　• provide economic benefits, and

　　• reduce reliance on raw materials and energy.

　　16.10.2 Supporting indicator requirement

　　The percentage of the city’s hazardous waste that is recycled shall be calculated as the total amount of hazardous waste that is recycled in tonnes (numerator) divided by the total amount of hazardous waste that is generated in tonnes (denominator). The result shall then be multiplied by 100 and expressed as a percentage.

　　Recycled Hazardous Waste (or Hazardous Recyclables) shall refer to hazardous waste that is used, reused, or reclaimed.
