Definitions
- Crime > Violent crime > Murder rate: Intentional homicide, number and rate per 100,000 population.
- Economy > Budget surplus > + or deficit > -: This entry records the difference between national government revenues and expenditures, expressed as a percent of GDP. A positive (+) number indicates that revenues exceeded expenditures (a budget surplus), while a negative (-) number indicates the reverse (a budget deficit). Normalizing the data, by dividing the budget balance by GDP, enables easy comparisons across countries and indicates whether a national government saves or borrows money. Countries with high budget deficits (relative to their GDPs) generally have more difficulty raising funds to finance expenditures, than those with lower deficits.
- Economy > Population below poverty line: National estimates of the percentage of the population lying below the poverty line are based on surveys of sub-groups, with the results weighted by the number of people in each group. Definitions of poverty vary considerably among nations. For example, rich nations generally employ more generous standards of poverty than poor nations.
- Economy > Unemployment rate: This entry contains the percent of the labor force that is without jobs. Substantial underemployment might be noted.

- Economy > Economy > Overview: This entry briefly describes the type of economy, including the degree of market orientation, the level of economic development, the most important natural resources, and the unique areas of specialization. It also characterizes major economic events and policy changes in the most recent 12 months and may include a statement about one or two key future macroeconomic trends.
- Economy > Exports: This entry provides the total US dollar amount of merchandise exports on an f.o.b. (free on board) basis. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.
- Crime > Violent crime > Murders: Intentional homicide, number and rate per 100,000 population.
- Government > Executive branch > Cabinet: Cabinet includes the official name for any body of high-ranking advisers roughly comparable to a U.S. Cabinet. Also notes the method for selection of members.
- Education > Compulsary education duration: Number of years students are required to be enrolled in school for all levels of education. For instance, compulsary education lasts for 12 years in the United States.
- Economy > GDP > Per capita: This entry gives the gross domestic product (GDP) or value of all final goods and services produced within a nation in a given year. A nation's GDP at purchasing power parity (PPP) exchange rates is the sum value of all goods and services produced in the country valued at prices prevailing in the United States. This is the measure most economists prefer when looking at per-capita welfare and when comparing living conditions or use of resources across countries. The measure is difficult to compute, as a US dollar value has to be assigned to all goods and services in the country regardless of whether these goods and services have a direct equivalent in the United States (for example, the value of an ox-cart or non-US military equipment); as a result, PPP estimates for some countries are based on a small and sometimes different set of goods and services. In addition, many countries do not formally participate in the World Bank's PPP project that calculates these measures, so the resulting GDP estimates for these countries may lack precision. For many developing countries, PPP-based GDP measures are multiples of the official exchange rate (OER) measure. The difference between the OER- and PPP-denominated GDP values for most of the weathly industrialized countries are generally much smaller. Per capita figures expressed per 1 population.
- Agriculture > Rural population: Total population living in rural areas. Future estimates are from the UN Population Division.
- Energy > Electricity > Consumption > Per capita: Total electricity consumed annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution. Per capita figures expressed per 1 population.
- People > Death rate: The average annual number of deaths during a year per 1,000 population at midyear; also known as crude death rate. The death rate, while only a rough indicator of the mortality situation in a country, accurately indicates the current mortality impact on population growth. This indicator is significantly affected by age distribution, and most countries will eventually show a rise in the overall death rate, in spite of continued decline in mortality at all ages, as declining fertility results in an aging population.
- Government > Political pressure groups and leaders: Organizations with leaders involved in politics, but not standing for legislative election.
- Geography > Natural resources: A country's mineral, petroleum, hydropower, and other resources of commercial importance.
- Energy > Electricity > Consumption: Total electricity consumed annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.
- People > Population growth rate: The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative. The growth rate is a factor in determining how great a burden would be imposed on a country by the changing needs of its people for infrastructure (e.g., schools, hospitals, housing, roads), resources (e.g., food, water, electricity), and jobs. Rapid population growth can be seen as threatening by neighboring countries.
- Geography > Area > Land > Per capita: Total land area in square kilometres Per capita figures expressed per 1,000 population.
- Media > Internet > Internet users per thousand people: Internet users. Figures expressed per thousand people for the same year.
- Economy > Public debt: This entry records the cumulatiive total of all government borrowings less repayments that are denominated in a country's home currency.

- Language > Languages: A rank ordering of languages starting with the largest and sometimes includes the percent of total population speaking that language.
- Transport > Road network length > Km: Length of road network in kilometers in European Union countries.
- Economy > GDP > Composition, by sector of origin > Services: This entry is derived from Economy > GDP > Composition, by sector of origin, which shows where production takes place in an economy. The distribution gives the percentage contribution of agriculture, industry, and services to total GDP, and will total 100 percent of GDP if the data are complete. Agriculture includes farming, fishing, and forestry. Industry includes mining, manufacturing, energy production, and construction. Services cover government activities, communications, transportation, finance, and all other private economic activities that do not produce material goods.
- Economy > Exports per capita: This entry provides the total US dollar amount of merchandise exports on an f.o.b. (free on board) basis. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms. Figures expressed per capita for the same year.
- Government > Administrative divisions: This entry generally gives the numbers, designatory terms, and first-order administrative divisions as approved by the US Board on Geographic Names (BGN). Changes that have been reported but not yet acted on by BGN are noted.
- Education > Literacy > Total population: This entry includes a definition of literacy and Census Bureau percentages for the total population, males, and females. There are no universal definitions and standards of literacy. Unless otherwise specified, all rates are based on the most common definition - the ability to read and write at a specified age. Detailing the standards that individual countries use to assess the ability to read and write is beyond the scope of our source. Information on literacy, while not a perfect measure of educational results, is probably the most easily available and valid for international comparisons.

- People > Total fertility rate: The average number of children that would be born per woman if all women lived to the end of their child-bearing years and bore children according to a given fertility rate at each age. The total fertility rate is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. This indicator shows the potential for population growth in the country. High rates will also place some limits on the labor force participation rates for women. Large numbers of children born to women indicate large family sizes that might limit the ability of the families to feed and educate their children.
- Government > Executive branch > Chief of state: The name and title of any person or role roughly equivalent to a U.S. Chief of State. This means the titular leader of the country who represents the state at official and ceremonial functions but may not be involved with the day-to-day activities of the government
- Economy > GDP > Purchasing power parity: This entry gives the gross domestic product (GDP) or value of all final goods and services produced within a nation in a given year. A nation's GDP at purchasing power parity (PPP) exchange rates is the sum value of all goods and services produced in the country valued at prices prevailing in the United States. This is the measure most economists prefer when looking at per-capita welfare and when comparing living conditions or use of resources across countries. The measure is difficult to compute, as a US dollar value has to be assigned to all goods and services in the country regardless of whether these goods and services have a direct equivalent in the United States (for example, the value of an ox-cart or non-US military equipment); as a result, PPP estimates for some countries are based on a small and sometimes different set of goods and services.

Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.

There are no universal definitions and standards of literacy. Unless otherwise specified, all rates are based on the most common definition - the ability to read and write at a specified age. Detailing the standards that individual countries use to assess the ability to read and write is beyond the scope of our source. Information on literacy, while not a perfect measure of educational results, is probably the most easily available and valid for international comparisons.
