The 1997 CIA World Factbook. United States. Central Intelligence Agency
changed to Democratic Republic of the Congo. Congo is now referred to as Republic of the Congo. New reference maps of the United States, Ethnolinguistic Groups in Afghanistan, and Central Africa have been included. Introduction is a new category with two entries—Current issues and Historical perspective that now appear in only a few country profiles, but will be added to all countries in the future. The Area—comparative entry was separated from the Area entry. The lowest point and highest point information has been removed from the Terrain entry and put into a new entry called Elevation extremes. The former Environment entry has been replaced by three new entries—Natural hazards, Environment—current issues, and Environment—international agreements. US diplomatic representation has been renamed Diplomatic representation from the US in order to parallel the Diplomatic representation in the US entry. The former Airports entry has been split into three separate entries—Airports, Airports—with paved runways, and Airports—with unpaved runways. The Defense category has been renamed Military. The Branches entry has been renamed Military branches. The former Manpower availability entry has been replaced by four new entries—Military manpower—military age, Military manpower—availability, Military manpower—fit for military service, and Military manpower—reaching military age annually. The former Defense expenditures entry has been replaced by two new entries—Military expenditures—dollar figure, and Military expenditures—percent of GDP. Transnational Issues is a new category that now includes only two existing entries (Illicit drugs and Disputes—international) but additional entries will be considered in the future.
Abbreviations: This information is included in Appendix A: Abbreviations which includes all abbreviations and acronyms used in the Factbook with their expansions.
Administrative divisions: This entry generally gives the numbers, designatory terms, and first-order administrative divisions as approved by the US Board on Geographic Names (BGN). Changes that have been reported but not yet acted on by BGN are noted.
Age structure: This entry provides the distribution of the population according to age. Information is included by sex and age group (0–14 years, 15–64 years, 65 years and over). The age structure of a population will affect a country's investment pattern. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to 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. Not all airports have facilities for refueling, maintenance, or air traffic control. Only airports with usable runways are included in this listing.
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. Not all airports have facilities for refueling, maintenance, or air traffic control. Only airports with usable runways are included in this listing.
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).
Birth rate: This entry gives the average annual number of births during a year per 1,000 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.
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 radio, telephone, 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. See the Terminology note regarding the use of the term "country."
Currency: This entry identifies the local medium of exchange and its basic subunit.
Current issues: This entry briefly characterizes major geographic, social, political, and military developments in the past 12 months 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.
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 codes and Appendix G does the same thing for hydrographic 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), the International Organization for Standardization (ISO), and Internet country codes.
Data codes—hydrographic: This information is presented in Appendix G:
Cross-Reference List of Hydrographic Data Codes which includes the
International Hydrographic Organization (IHO), Aeronautical Chart and
Information Center (ACIC; now National Imagery and Mapping Agency or
NIMA), and Defense Intelligence Agency (DIA) hydrographic codes. The
