Index Definition
GDP per capita (current US$) GDP per capita is gross domestic product divided by midyear population. GDP is the sum of gross value added by all resident producers in the economy plus any product taxes and minus any subsidies not included in the value of the products. It is calculated without making deductions for depreciation of fabricated assets or for depletion and degradation of natural resources. Data are in current U.S. dollars.
Ease of doing business A high ranking on the ease of doing business index means the regulatory environment is more conducive to the starting and operation of a local firm. This index averages the country's percentile rankings on 9 topics: starting a business, dealing with construction permits, registering property, getting credit, protecting investors, paying taxes, trading across borders, enforcing contracts and closing a business. The ranking on each topic is the simple average of the percentile rankings on its component indicators.
Unemployment, total (% of total labor force) Unemployment refers to the share of the labor force that is without work but available for and seeking employment. Definitions of labor force and unemployment differ by country.
Gini index Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure) among individuals or households within an economy deviates from a perfectly equal distribution. A Lorenz curve plots the cumulative percentages of total income received against the cumulative number of recipients, starting with the poorest individual or household. The Gini index measures the area between the Lorenz curve and a hypothetical line of absolute equality, expressed as a percentage of the maximum area under the line. Thus a Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality
Inflation, average consumer prices (% change) Inflation as measured by the consumer price index reflects the annual percentage change in the cost to the average consumer of acquiring a basket of goods and services that may be fixed or changed at specified intervals, such as yearly.
Adult (15+) literacy rate (%)Total population  Adult literacy rate is the percentage of people ages 15 and above who can, with understanding, read and write a short, simple statement on their everyday life.
Gender parity index for adult literacy rate The number of literate women divided by the number of literate men in the population aged 15 years and above. Literacy among men and women is one aspect of gender equality.
School enrollment, secondary (% net) The ratio of children of official school age based on the International Standard Classification of Education 1997 who are enrolled in school to the population of the corresponding official school age. Secondary education completes the provision of basic education that began at the primary level, and aims at laying the foundations for lifelong learning and human development, by offering more subject- or skill-oriented instruction using more specialized teachers.
Overall reading scale Tests an individual’s capacity to understand, use, reflect on and engage with written texts. Results from PISA have been reported using scales with an average score of 500 and a standard deviation of 100 for all three domains, which means that two-thirds of students across OECD countries scored between 400 and 600 points.
Overall mathematics scale Tests an individual’s capacity to identify and understand the role that mathematics plays in the world, to make well-founded judgements and to use and engage with mathematics in ways that meet the needs of that individual’s life as a constructive, concerned and reflective citizen.Results from PISA have been reported using scales with an average score of 500 and a standard deviation of 100 for all three domains, which means that two-thirds of students across OECD countries scored between 400 and 600 points.
Overall science scale Tests an individual’s scientific knowledge and use of that knowledge to identify questions, to acquire new knowledge, to explain scientific phenomena, and to draw evidencebased conclusions about science-related issues.Results from PISA have been reported using scales with an average score of 500 and a standard deviation of 100 for all three domains, which means that two-thirds of students across OECD countries scored between 400 and 600 points.
GEF benefits index for biodiversity GEF benefits index for biodiversity is a composite index of relative biodiversity potential for each country based on the species represented in each country, their threat status, and the diversity of habitat types in each country. The index has been normalized so that values run from 0 (no biodiversity potential) to 100 (maximum biodiversity potential).
CO2 emissions (metric tons per capita) Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. They include carbon dioxide produced during consumption of solid, liquid, and gas fuels and gas flaring.
Environmental Disasters (number of deaths) The environmental disasters include droughts, earthquakes, extreme temperatures, floods, storms, volcano eruptions and wildfires.
Industial/Transprort accidents (total number of affected) Industrial, transport and miscellaneous accidents are included. Total affected are those injured, homeless or people requiring immediate assistance during a period of emergency; it can also include displaced or evacuated people.
Hazardous waste generation (tonnes) The total amount of hazardous wastes generated per year through industrial or other waste generating activities, according to the definition of hazardous waste as referred to in the Basel Convention and other related conventions. Hazardous waste is waste that owing to its toxic, infectious, radioactive or flammable properties poses an actual or potential hazard to the health of humans, other living organisms, or the environment. Hazardous waste here refers to categories of waste to be controlled according to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal. If data are not available according to the Basel Convention, amounts can be given according to national definitions.
Overall Life Expectancy at Birth (in Years) Number of years a newborn infant could expect to live if prevailing patterns of age-specific mortality rates at the time of birth were to stay the same throughout the infant’s life.
Difference between female and male life expectancy at birth (2008, revised 2010)  
Malnutrition prevalence, weight for age (% of children under 5) Prevalence of child malnutrition is the percentage of children under age 5 whose weight for age is more than two standard deviations below the median for the international reference population ages 0-59 months. The data are based on the WHO's new child growth standards released in 2006. 
Healthy life expectancy (in Years) Healthy life expectancy is based on life expectancy, but includes an adjustment for time spent in poor health. This indicator measures the equivalent number of years in full health that a newborn child can expect to live based on the current mortality rates and prevalence distribution of health states in the population. Estimates of healthy life expectancy at birth and age 60, and expected lost years of healthy life at birth, by sex and WHO Member State are available for 2002
Democracy Index The index is based on 60 indicators grouped in five different categories: electoral process and pluralism, civil liberties, functioning of government, political participation and political culture.
Intentional homicide, rate per 100,000 population Intentional homicide is defined as unlawful death purposefully inflicted on a person by another person
Corruption perceptions index Scores beween 10-9: All integrity mechanisms are reasonably effective. They are actively supported by the government. 8-6: Most integrity mechanisms are functioning, albeit partly with limited effectiveness. The government provides almost all integrity mechanisms. 5-3: Some integrity mechanisms are implemented. Often, they remain ineffective; their operation is impeded by private interests. The government’s motivation and capacity to implement reforms is mixed. 2-1: Portions of the state are controlled by private interest groups; reform is impeded by private interests, rendering most integrity mechanisms nonexistent or ineffective.
Prison population rate (per 100000 of the population)  
Willingness to fight Qualitative assesment of the willingness of citizens to fight in wars. 1=very low, 5=very high 
Level of violent crime Qualitative assesment of the level of crime within a country. 1=very low, 5=very high 
Total Population (both sexes) Countries with a population of 10 million or above were categorized as large countries. Countries with a smaller population were categorized as small countries.
