Overview:

• Budget > Revenues: Revenues calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms
• 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.
• Debt > Government debt > Public debt, share of GDP: Public debt as % of GDP (CIA).

• 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.
• GDP: GDP at purchaser's prices 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. Dollar figures for GDP are converted from domestic currencies using single year official exchange rates. For a few countries where the official exchange rate does not reflect the rate effectively applied to actual foreign exchange transactions, an alternative conversion factor is used.
• 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 ofagriculture, industry, andservices 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.
• 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.
• GDP > Per capita > PPP: This entry shows GDP on a purchasing power parity basis divided by population as of 1 July for the same year.
• GDP > Purchasing power parity 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.

Figures expressed per capita for the same year.
• Gross National Income: GNI,Atlas method (current US$). GNI (formerly GNP) is the sum ofvalue added by all resident producers plus any product taxes (lesssubsidies) not included in the valuation of output plus net receipts of primary income (compensation of employees and prop).
• Inflation rate > Consumer prices: This entry furnishes the annual percent change in consumer prices compared with the previous year's consumer prices.
• 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.
• Public debt: This entry records the cumulatiive total of all government borrowings less repayments that are denominated in a country's home currency. Public debt should not be confused with external debt, which reflects the foreign currency liabilities of both the private and public sector and must be financed out of foreign exchange earnings.
• Unemployment rate: This entry contains the percent of the labor force that is without jobs. Substantial underemployment might be noted.
