Factbook fields with Rank Order pages are easily identified with a small bar chart icon to the right of the data field title.

Not all Rank Order pages include the same number of entries because information for a particular field is not available for all countries. In addition, not all data fields are suitable for displaying as Rank Order pages, such as those containing textual information. Textual information is more readily viewed by clicking on the Field Listing icon next to the Data field title. The other icon next to the data field title provides the definition of the field.

All of the 'Rank Order' pages can be downloaded as tab-delimited data files and can be opened in other applications such as spreadsheets and databases. To save a Rank Order page in a spreadsheet, first click on the 'Download Datafile' choice above the Rank Order page you selected; then, at the top of your browser window, click on 'File' and 'Save As'. After saving the file, open the spreadsheet, find the saved file, and 'Open' it.

Additional Rank Order pages being considered for future updates of the
Factbook Web site include:

  Median age
  Literacy
  Population below the poverty line
  Waterways
  Airports

Notes and Definitions

Along with the new entities and the regular information updates, The World Factbook now also features six new fields. In the Economy category, entries have been added for Current account balance, Investment (gross fixed), Public debt, and Reserves of foreign exchange and gold. The Transnational issues category has a new Refugees and internally displaced persons entry. Revision of some individual country maps, first introduced in the 2001 edition, is continued in this edition. 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 (WTO: WTrO 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. 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) 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 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
