Notes and Definitions
- Date of information:
- In general, information available as of 1 January 2005, was used in the preparation of this edition.
- Death rate:
- This entry gives 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.
- Debt - external:
- This entry gives the total public and private debt owed to nonresidents repayable in foreign currency, goods, or services. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.
- Dependency status:
- This entry describes the formal relationship between a particular nonindependent entity and an independent state.
- Dependent areas:
- This entry contains an alphabetical listing of all nonindependent entities associated in some way with a particular independent state.
- Diplomatic representation:
- The US Government has diplomatic relations with 187 independent states, including 186 of the 191 UN members (excluded UN members are Bhutan, Cuba, Iran, North Korea, and the US itself). In addition, the US has diplomatic relations with 1 independent state that is not in the UN - Holy See.
- Diplomatic representation from the US:
- This entry includes the chief of mission, embassy address, mailing address, telephone number, FAX number, branch office locations, consulate general locations, and consulate locations.
- Diplomatic representation in the US:
- This entry includes the chief of mission, chancery address, telephone number, FAX number, consulate general locations, and consulate locations.
- Disputes - international:
- This entry includes a wide variety of situations that range from traditional bilateral boundary disputes to unilateral claims of one sort or another. Information regarding disputes over international terrestrial and maritime boundaries has been reviewed by the US Department of State. References to other situations involving borders or frontiers may also be included, such as resource disputes, geopolitical questions, or irredentist issues; however, inclusion does not necessarily constitute official acceptance or recognition by the US Government.
- 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.
