unrest.
Agriculture—products: This entry is a rank ordering of major crops and products starting with the most important.
Airports: This entry gives the total number of airports. The runway(s) may be paved (concrete or asphalt surfaces) or unpaved (grass, dirt, sand, or gravel surfaces), but must be usable. Not all airports have facilities for refueling, maintenance, or air traffic control.
Airports—with paved runways: This entry gives the total number of airports with paved runways (concrete or asphalt surfaces). For airports with more than one runway, only the longest runway is included according to the following five groups—(1) over 3,047 m, (2) 2,438 to 3,047 m, (3) 1,524 to 2,437 m, (4) 914 to 1,523 m, and (5) under 914 m. Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control.
Airports—with unpaved runways: This entry gives the total number of airports with unpaved runways (grass, dirt, sand, or gravel surfaces). For airports with more than one runway, only the longest runway is included according to the following five groups—(1) over 3,047 m, (2) 2,438 to 3,047 m, (3) 1,524 to 2,437 m, (4) 914 to 1,523 m, and (5) under 914 m. Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control.
Appendixes: This section includes Factbook-related material by topic.
Area: This entry includes three subfields. Total area is the sum of all land and water areas delimited by international boundaries and/or coastlines. Land area is the aggregate of all surfaces delimited by international boundaries and/or coastlines, excluding inland water bodies (lakes, reservoirs, rivers). Water area is the sum of all water surfaces delimited by international boundaries and/or coastlines, including inland water bodies (lakes, reservoirs, rivers).
Area—comparative: This entry provides an area comparison based on total area equivalents. Most entities are compared with the entire US or one of the 50 states based on area measurements (1990 revised) provided by the US 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, current issues, and may include a statement about one or two key future trends. This entry appears for only a few countries at the present time, but will be added to all countries in the future.
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, and television 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 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.
Currency: This entry identifies the national medium of exchange and its basic subunit.
Data code: This entry gives the official US Government digraph that precisely identifies every land entity without overlap, duplication, or omission. AF, for example, is the data code for Afghanistan. This two-letter country code is a standardized geopolitical data element promulgated in the Federal Information Processing Standards Publication (FIPS) 10–4 by the National Institute of Standards and Technology at the US Department of Commerce and maintained by the Office of the Geographer and Global Issues at the US Department of State. The data code is used to eliminate confusion and incompatibility in the collection, processing, and dissemination of area-specific data and is particularly useful for interchanging data between databases. Appendix F cross-references various country data codes and Appendix G does the same thing for hydrographic data codes.
Data codes—country: This information is presented in Appendix F: Cross-Reference List of Country Data Codes which includes the US Government approved Federal Information Processing Standards (FIPS) codes, the International Organization for Standardization (ISO) codes, and Internet codes for land entities.
Data codes—hydrographic: This information is presented in Appendix G: Cross-Reference List of Hydrographic Data Codes which includes the International Hydrographic Organization (IHO) codes, Aeronautical Chart and Information Center (ACIC; now National Imagery and Mapping Agency or NIMA) 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 1999, 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 amount of public foreign financial obligations.
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 184 independent states, including 178 of the 185 UN members (excluded UN members are Bhutan, Cuba, Iran, Iraq, North Korea, former Yugoslavia, and the US itself). In addition, the US has diplomatic relations with 6 independent states that are not in the UN—Holy See, Kiribati, Nauru, Switzerland, Tonga, and Tuvalu.
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.
