Bureau of the Census. The smaller entities are compared with Washington, DC (178 sq km, 69 sq mi) or The Mall in Washington, DC (0.59 sq km, 0.23 sq mi, 146 acres).

Background This entry usually highlights major historic events and current issues and may include a statement about one or two key future trends.

Birth rate This entry gives the average annual number of births during a year per 1,000 persons in the population at midyear; also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population.

Budget This entry includes revenues, total expenditures, and capital expenditures. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms

Capital
This entry gives the location of the seat of government.

Climate This entry includes a brief description of typical weather regimes throughout the year.

Coastline This entry gives the total length of the boundary between the land area (including islands) and the sea.

Communications This category deals with the means of exchanging information and includes the telephone, radio, television, and Internet service provider entries.

Communications - note This entry includes miscellaneous communications information of significance not included elsewhere.

Constitution This entry includes the dates of adoption, revisions, and major amendments.

Country data codes see Data codes

Country map Most versions of the Factbook provide a country map in color. The maps were produced from the best information available at the time of preparation. Names and/or boundaries may have changed subsequently.

Country name This entry includes all forms of the country's name approved by the US Board on Geographic Names (Italy is used as an example): conventional long form (Italian Republic), conventional short form (Italy), local long form (Repubblica Italiana), local short form (Italia), former (Kingdom of Italy), as well as the abbreviation. Also see the Terminology note.

Crude oil
See entry for oil.

Currency This entry identifies the national medium of exchange and its basic subunit.

Currency code
This entry gives the International Organization for Standardization
(ISO) 4217 alphabetic currency code for each country.

Current account balance This entry records a country's net trade in goods and services, plus net earnings from rents, interest, profits, and dividends, and net transfer payments (such as pension funds and worker remittances) to and from the rest of the world during the period specified.

Data codes This information is presented in Appendix D: Cross-Reference List of Country Data Codes and Appendix E: Cross-Reference List of Hydrographic Data Codes. This appendix includes the US Government approved Federal Information Processing Standards (FIPS) codes, the International Organization for Standardization (ISO) codes, and Internet codes for land entities. The appendix also includes the International Hydrographic Organization (IHO) codes, Aeronautical Chart and Information Center (ACIC; now a part of the National Geospatial- Intelligence Agency or NGA) codes, and Defense Intelligence Agency (DIA) codes for hydrographic entities. The US Government has not yet approved a standard for hydrographic data codes similar to the FIPS 10- 4 standard for country data codes.

Date of information In general, information available as of 1 January 2004, 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.

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 186 independent states, including 185 of the 191 UN members (excluded UN members are Bhutan, Cuba, Iran, Iraq, 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 in the US This entry includes the chief of mission, chancery, telephone, FAX, consulate general locations, and consulate locations.

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.

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.

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
