Notes and Definitions
In addition to the regular information updates, The World Factbook 2008 features several new additions. In the Geography category, two new fields focus on the increasingly vital resource of water: "Total renewable water resources" and "Freshwater withdrawal."
In the Economy category, the Factbook has added three fields: "Stock of direct foreign investment - at home", "Stock of direct foreign investment - abroad", and "Market value of publicly traded shares." Additionally, the data for GDP at purchasing power parity (PPP) has been rebased using new PPP conversion rates, benchmarked to the year 2005, which were released on 17 December 2007 by the International Comparison Program (ICP). The 2005 PPP data replace previous estimates, many from studies dating to 1993 or earlier. The preliminary ICP report provides estimates of internationally comparable price levels and the relative purchasing power of currencies for 146 countries. The 2005 benchmark revises downward the size of the world economy in PPP terms from the previous estimates, and changes the relative sizes of many of the world's economies.
Concise descriptions of the major religions mentioned in the Factbook have been added to the Notes and Definitions. France 's redesignation of some of its overseas possessions caused the five former Indian Ocean island possessions making up Iles Eparses to be incorporated into the French Southern and Antarctic Lands, while two new Caribbean entities, St. Barthelemy and St. Martin, were created.
Revision of some individual country maps, first introduced in the 2001 edition, is continued in this edition. The revised maps include elevation extremes and a partial geographic grid. Several regional maps have also been updated to reflect boundary changes and place name spelling changes.
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 (ICC for International Chamber of Commerce and ICCt for International Criminal Court).
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 the 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 accommodations 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.
Central bank discount rate: This entry provides the annualized interest rate a country's central bank charges commercial, depository banks for loans to meet temporary shortages of funds.
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.
