Distribution of family income - Gini index This index measures the degree of inequality in the distribution of family income in a country. The index is calculated from the Lorenz curve, in which cumulative family income is plotted against the number of families arranged from the poorest to the richest. The index is the ratio of (a) the area between a country's Lorenz curve and the 45 degree helping line to (b) the entire triangular area under the 45 degree line. The more nearly equal a country's income distribution, the closer its Lorenz curve to the 45 degree line and the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country's income distribution, the farther its Lorenz curve from the 45 degree line and the higher its Gini index, e.g., a Sub- Saharan country with an index of 50. If income were distributed with perfect equality, the Lorenz curve would coincide with the 45 degree line and the index would be zero; if income were distributed with perfect inequality, the Lorenz curve would coincide with the horizontal axis and the right vertical axis and the index would be 100.

Economic aid - donor This entry refers to net official development assistance (ODA) from Organization for Economic Cooperation and Development (OECD) nations to developing countries and multilateral organizations. ODA is defined as financial assistance that is concessional in character, has the main objective to promote economic development and welfare of the less developed countries (LDCs), and contains a grant element of at least 25%. The entry does not cover other official flows (OOF) or private flows.

Economic aid - recipient This entry, which is subject to major problems of definition and statistical coverage, refers to the net inflow of Official Development Finance (ODF) to recipient countries. The figure includes assistance from the World Bank, the IMF, and other international organizations and from individual nation donors. Formal commitments of aid are included in the data. Omitted from the data are grants by private organizations. Aid comes in various forms including outright grants and loans. The entry thus is the difference between new inflows and repayments.

Economy This category includes the entries dealing with the size, development, and management of productive resources, i.e., land, labor, and capital.

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.

Electricity - consumption This entry consists of total electricity generated 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.

Electricity - exports
This entry is the total exported electricity in kilowatt-hours.

Electricity - imports
This entry is the total imported electricity in kilowatt-hours.

Electricity - production This entry is the annual electricity generated 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.

Electricity - production by source This entry states the percentage share of electricity generated from each energy source. These are fossil fuel, hydro, nuclear, and other (solar, geothermal, and wind).
