Notes and Definitions

Along with regular information updates, The World Factbook features several new or revised fields. In the Economy category, the Factbook is now reporting national GDP figures in US dollars converted at Official Exchange Rates (OER) in addition to GDP at Purchasing Power Parity (PPP) rates, since both measures contain information useful to our readers. Traditionally, only PPP-converted GDP values had been reported. In the Transportation category, the former Highways entry is now Roadways, while Ports and harbors has been retitled Ports and terminals.

Abbreviations

This information is included in Appendix A: Abbreviations, which includes all abbreviations and acronyms used in the Factbook, with their expansions.

Acronyms

An acronym is an abbreviation coined from the initial letter of each successive word in a term or phrase. In general, an acronym made up solely from the first letter of the major words in the expanded form is rendered in all capital letters (NATO from North Atlantic Treaty Organization; an exception would be ASEAN for Association of Southeast Asian Nations). In general, an acronym made up of more than the first letter of the major words in the expanded form is rendered with only an initial capital letter (Comsat from Communications Satellite Corporation; an exception would be NAM from Nonaligned Movement). Hybrid forms are sometimes used to distinguish between initially identical terms (WTO: for World Trade Organization and WToO for World Tourism Organization.)

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 affects a nation's key socioeconomic issues. 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 an ordered listing of major crops and products starting with the most important.

Airports

This entry gives the total number of airports or airfields recognizable from the air. The runway(s) may be paved (concrete or asphalt surfaces) or unpaved (grass, earth, sand, or gravel surfaces) but may include closed or abandoned installations. Airports or airfields that are no longer recognizable (overgrown, no facilities, etc.) are not included. Note that not all airports have accomodations 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) by length. 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) by length. 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 the surfaces of all inland water bodies, such as lakes, reservoirs, or rivers, as delimited by international boundaries and/or coastlines.

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 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, 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 name of the seat of government, its geographic coordinates, the time difference relative to Coordinated Universal Time (UTC) and the time observed in Washington, DC, and, if applicable, information on daylight saving time (DST). Where appropriate, a special note has been added to highlight those countries that have multiple time zones.

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 host 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.

Coordinated Universal Time (UTC)

UTC is the international atomic time scale that serves as the basis of timekeeping for most of the world. The hours, minutes, and seconds expressed by UTC represent the time of day at the Prime Meridian (0º longitude) located near Greenwich, England as reckoned from midnight. UTC is calculated by the Bureau International des Poids et Measures (BIPM) in Sevres, France. The BIPM averages data collected from more than 200 atomic time and frequency standards located at about 50 laboratories worldwide. UTC is the basis for all civil time with the Earth divided into time zones expressed as positive or negative differences from UTC. UTC is also referred to as "Zulu time." See the Standard Time Zones of the World map included with the Reference Maps.

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 (code)

This entry identifies the national medium of exchange and, in parenthesis, 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. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.

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.

Date of information

In general, information available as of 1 January 2006, was used in the preparation of this edition.

Daylight Saving Time (DST)

This entry is included for those entities that have adopted a policy of adjusting the official local time forward, usually one hour, from Standard Time during summer months. Such policies are most common in mid-latitude regions.

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.
