Home Reference Maps Appendixes

In addition to the updated information, The World Factbook printed version features seven new entries. In the People category, an entry has been added for Median age. In the Economy category, entries have been added for Oil - production, Oil - consumption, Oil - exports, Oil - imports, Oil - proved reserves, and Natural gas - proved reserves. The web site version features four additional entries: Natural gas - production, Natural gas - consumption, Natural gas - exports, and Natural gas - imports. 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 (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 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) 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 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, 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, television, and Internet service provider 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 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.
Currency	This entry identifies the national medium of exchange and its basic subunit.
Crude oil	See “Oil” entries
Currency code	This entry gives the International Organization for Standardization (ISO) 4217 alphabetic currency code for each country.
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. This appendix includes the US Government approved Federal Information Processing Standards (FIPS) codes, the International Organization for Standardization (ISO) codes, and Internet codes for land entities. The appendix also includes the International Hydrographic Organization (IHO) codes, Aeronautical Chart and Information Center (ACIC; now a part of the 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 2003 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 public and private debt owed to nonresidents repayable in foreign currency, goods, or services.
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 185 independent states, including 183 of the 189 UN members (excluded UN members are Bhutan, Cuba, Iran, Iraq, North Korea, and the US itself). In addition, the US has diplomatic relations with 1 independent state that is not in the UN - Holy See.
Diplomatic representation in the US	This entry includes the chief of mission, chancery, telephone, FAX, consulate general locations, and consulate locations.
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.
Disputes - international	This entry includes a wide variety of situations that range from traditional bilateral boundary disputes to unilateral claims of one sort or another. Information regarding disputes over international terrestrial and maritime boundaries has been reviewed by the US Department of State. References to other situations involving borders or frontiers may also be included, such as resource disputes, geopolitical questions, or irredentist issues; however, inclusion does not necessarily constitute official acceptance or recognition by the US Government.
Distribution of family income - Gini index	This index measures the degree of inequality in the distribution of family income in a country. The index is calculated from the Lorenz curve, in which cumulative family income is plotted against the number of families arranged from the poorest to the richest. The index is the ratio of (a) the area between a country's Lorenz curve and the 45 degree helping line to (b) the entire triangular area under the 45 degree line. The more nearly equal a country's income distribution, the closer its Lorenz curve to the 45-degree line and the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country's income distribution, the farther its Lorenz curve from the 45-degree line and the higher its Gini index, e.g., a Sub-Saharan country with an index of 50. If income were distributed with perfect equality, the Lorenz curve would coincide with the 45 degree line and the index would be zero; if income were distributed with perfect inequality, the Lorenz curve would coincide with the horizontal axis and the right vertical axis and the index would be 100.
Economic aid - donor	This entry refers to net official development assistance (ODA) from Organization for Economic Cooperation and Development (OECD) nations to developing countries and multilateral organizations. ODA is defined as financial assistance that is concessional in character, has the main objective to promote economic development and welfare of the less developed countries (LDCs), and contains a grant element of at least 25%. The entry does not cover other official flows (OOF) or private flows.
Economic aid - recipient	This entry, which is subject to major problems of definition and statistical coverage, refers to the net inflow of Official Development Finance (ODF) to recipient countries. The figure includes assistance from the World Bank, the IMF, and other international organizations and from individual nation donors. Formal commitments of aid are included in the data. Omitted from the data are grants by private organizations. Aid comes in various forms including outright grants and loans. The entry thus is the difference between new inflows and repayments.
Economy	This category includes the entries dealing with the size, development, and management of productive resources, i.e., land, labor, and capital.
Economy - overview	This entry briefly describes the type of economy, including the degree of market orientation, the level of economic development, the most important natural resources, and the unique areas of specialization. It also characterizes major economic events and policy changes in the most recent 12 months and may include a statement about one or two key future macroeconomic trends.
Electricity - consumption	This entry consists of total electricity generated annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.
Electricity - exports	This entry is the total exported electricity in kilowatt-hours.
Electricity - imports	This entry is the total imported electricity in kilowatt-hours.
Electricity - production	This entry is the annual electricity generated expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.
Electricity - production by source	This entry states the percentage share of electricity generated from each energy source. These are fossil fuel, hydro, nuclear, and other (solar, geothermal, and wind).
Elevation extremes	This entry includes both the highest point and the lowest point.
Entities	Some of the independent states, dependencies, areas of special sovereignty, and governments included in this publication are not independent, and others are not officially recognized by the US Government. "Independent state" refers to a people politically organized into a sovereign state with a definite territory. "Dependencies" and "areas of special sovereignty" refer to a broad category of political entities that are associated in some way with an independent state. "Country" names used in the table of contents or for page headings are usually the short-form names as approved by the US Board on Geographic Names and may include independent states, dependencies, and areas of special sovereignty, or other geographic entities. There are a total of 268 separate geographic entities in The World Factbook that may be categorized as follows: INDEPENDENT STATES 192 Afghanistan, Albania, Algeria, Andorra, Angola, Antigua and Barbuda, Argentina, Armenia, Australia, Austria, Azerbaijan, The Bahamas, Bahrain, Bangladesh, Barbados, Belarus, Belgium, Belize, Benin, Bhutan, Bolivia, Bosnia and Herzegovina, Botswana, Brazil, Brunei, Bulgaria, Burkina Faso, Burma, Burundi, Cambodia, Cameroon, Canada, Cape Verde, Central African Republic, Chad, Chile, China, Colombia, Comoros, Democratic Republic of the Congo, Republic of the Congo, Costa Rica, Cote d'Ivoire, Croatia, Cuba, Cyprus, Czech Republic, Denmark, Djibouti, Dominica, Dominican Republic, East Timor, Ecuador, Egypt, El Salvador, Equatorial Guinea, Eritrea, Estonia, Ethiopia, Fiji, Finland, France, Gabon, The Gambia, Georgia, Germany, Ghana, Greece, Grenada, Guatemala, Guinea, Guinea-Bissau, Guyana, Haiti, Holy See, Honduras, Hungary, Iceland, India, Indonesia, Iran, Iraq, Ireland, Israel, Italy, Jamaica, Japan, Jordan, Kazakhstan, Kenya, Kiribati, North Korea, South Korea, Kuwait, Kyrgyzstan, Laos, Latvia, Lebanon, Lesotho, Liberia, Libya, Liechtenstein, Lithuania, Luxembourg, The Former Yugoslav Republic of Macedonia, Madagascar, Malawi, Malaysia, Maldives, Mali, Malta, Marshall Islands, Mauritania, Mauritius, Mexico, Federated States of Micronesia, Moldova, Monaco, Mongolia, Morocco, Mozambique, Namibia, Nauru, Nepal, Netherlands, NZ, Nicaragua, Niger, Nigeria, Norway, Oman, Pakistan, Palau, Panama, Papua New Guinea, Paraguay, Peru, Philippines, Poland, Portugal, Qatar, Romania, Russia, Rwanda, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Samoa, San Marino, Sao Tome and Principe, Saudi Arabia, Senegal, Seychelles, Sierra Leone, Singapore, Slovakia, Slovenia, Solomon Islands, Somalia, South Africa, Spain, Sri Lanka, Sudan, Suriname, Swaziland, Sweden, Switzerland, Syria, Tajikistan, Tanzania, Thailand, Togo, Tonga, Trinidad and Tobago, Tunisia, Turkey, Turkmenistan, Tuvalu, Uganda, Ukraine, UAE, UK, US, Uruguay, Uzbekistan, Vanuatu, Venezuela, Vietnam, Yemen, Yugoslavia, Zambia, Zimbabwe OTHER 1 Taiwan DEPENDENCIES AND AREAS OF SPECIAL SOVEREIGNTY 6 Australia - Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, Norfolk Island 2 China - Hong Kong, Macau 2 Denmark - Faroe Islands, Greenland 16 France - Bassas da India, Clipperton Island, Europa Island, French Guiana, French Polynesia, French Southern and Antarctic Lands, Glorioso Islands, Guadeloupe, Juan de Nova Island, Martinique, Mayotte, New Caledonia, Reunion, Saint Pierre and Miquelon, Tromelin Island, Wallis and Futuna 2 Netherlands - Aruba, Netherlands Antilles 3 New Zealand - Cook Islands, Niue, Tokelau 3 Norway - Bouvet Island, Jan Mayen, Svalbard 15 UK - Anguilla, Bermuda, British Indian Ocean Territory, British Virgin Islands, Cayman Islands, Falkland Islands, Gibraltar, Guernsey, Jersey, Isle of Man, Montserrat, Pitcairn Islands, Saint Helena, South Georgia and the South Sandwich Islands, Turks and Caicos Islands 14 US - American Samoa, Baker Island, Guam, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Islands, Navassa Island, Northern Mariana Islands, Palmyra Atoll, Puerto Rico, Virgin Islands, Wake Island MISCELLANEOUS 6 Antarctica, Gaza Strip, Paracel Islands, Spratly Islands, West Bank, Western Sahara OTHER ENTITIES 5 oceans - Arctic Ocean, Atlantic Ocean, Indian Ocean, Pacific Ocean, Southern Ocean 1 World 268 total
Environment - current issues	This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry: acidification - the lowering of soil and water pH due to acid precipitation and deposition usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions (see acid rain). acid rain - characterized as containing harmful levels of sulfur dioxide or nitrogen oxide; acid rain is damaging and potentially deadly to the earth's fragile ecosystems; acidity is measured using the pH scale where 7 is neutral, values greater than 7 are considered alkaline, and values below 5.6 are considered acid precipitation; note - a pH of 2.4 (the acidity of vinegar) has been measured in rainfall in New England. aerosol - a collection of airborne particles dispersed in a gas, smoke, or fog. afforestation - converting a bare or agricultural space by planting trees and plants; reforestation involves replanting trees on areas that have been cut or destroyed by fire. asbestos - a naturally occurring soft fibrous mineral commonly used in fireproofing materials and considered to be highly carcinogenic in particulate form. biodiversity - also biological diversity; the relative number of species, diverse in form and function, at the genetic, organism, community, and ecosystem level; loss of biodiversity reduces an ecosystem’s ability to recover from natural or man-induced disruption. bio-indicators - a plant or animal species whose presence, abundance, and health reveal the general condition of its habitat. biomass - the total weight or volume of living matter in a given area or volume. carbon cycle - the term used to describe the exchange of carbon (in various forms, e.g., as carbon dioxide) between the atmosphere, ocean, terrestrial biosphere, and geological deposits. catchments - assemblages used to capture and retain rainwater and runoff; an important water management technique in areas with limited freshwater resources, such as Gibraltar. DDT (dichloro-diphenyl-trichloro-ethane) - a colorless, odorless insecticide that has toxic effects on most animals; the use of DDT was banned in the US in 1972. defoliants - chemicals which cause plants to lose their leaves artificially; often used in agricultural practices for weed control, and may have detrimental impacts on human and ecosystem health. deforestation - the destruction of vast areas of forest (e.g., unsustainable forestry practices, agricultural and range land clearing, and the over exploitation of wood products for use as fuel) without planting new growth. desertification - the spread of desert-like conditions in arid or semi-arid areas, due to overgrazing, loss of agriculturally productive soils, or climate change. dredging - the practice of deepening an existing waterway; also, a technique used for collecting bottom-dwelling marine organisms (e.g., shellfish) or harvesting coral, often causing significant destruction of reef and ocean-floor ecosystems. drift-net fishing - done with a net, miles in extent, that is generally anchored to a boat and left to float with the tide; often results in an over harvesting and waste of large populations of non-commercial marine species (by-catch) by its effect of “sweeping the ocean clean”. ecosystems - ecological units comprised of complex communities of organisms and their specific environments. effluents - waste materials, such as smoke, sewage, or industrial waste, which are released into the environment, subsequently polluting it. endangered species - a species that is threatened with extinction either by direct hunting or habitat destruction. freshwater - water with very low soluble mineral content; sources include lakes, streams, rivers, glaciers, and underground aquifers. greenhouse gas - a gas that “traps” infrared radiation in the lower atmosphere causing surface warming; water vapor, carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, and ozone are the primary greenhouse gases in the Earth’s atmosphere. groundwater - water sources found below the surface of the earth often in naturally occurring reservoirs in permeable rock strata; the source for wells and natural springs. Highlands Water Project - a series of dams constructed jointly by Lesotho and South Africa to redirect Lesotho's abundant water supply into a rapidly growing area in South Africa; while it is the largest infrastructure project in southern Africa, it is also the most costly and controversial; objections to the project include claims that it forces people from their homes, submerges farmlands, and squanders economic resources. Inuit Circumpolar Conference (ICC) - represents the 125,000 Inuits of Russia, Alaska, Canada, and Greenland in international environmental issues; a panel convenes every three years to determine the focus of the ICC; the most current concerns are long-range transport of pollutants, sustainable development, and climate change. metallurgical plants - industries which specialize in the science, technology, and processing of metals; these plants produce highly concentrated and toxic wastes which can contribute to pollution of ground water and air when not properly disposed. noxious substances - injurious, very harmful to living beings. overgrazing - the grazing of animals on plant material faster than it can naturally regrow leading to the permanent loss of plant cover, a common effect of too many animals grazing limited range land. ozone shield - a layer of the atmosphere composed of ozone gas (O3) that resides approximately 25 miles above the Earth's surface and absorbs solar ultraviolet radiation that can be harmful to living organisms. poaching - the illegal killing of animals or fish, a great concern with respect to endangered or threatened species. pollution - the contamination of a healthy environment by man-made waste. potable water - water that is drinkable, safe to be consumed. salination - the process through which fresh (drinkable) water becomes salt (undrinkable) water; hence, desalination is the reverse process; also involves the accumulation of salts in topsoil caused by evaporation of excessive irrigation water, a process that can eventually render soil incapable of supporting crops. siltation - occurs when water channels and reservoirs become clotted with silt and mud, a side effect of deforestation and soil erosion. slash-and-burn agriculture - a rotating cultivation technique in which trees are cut down and burned in order to clear land for temporary agriculture; the land is used until its productivity declines at which point a new plot is selected and the process repeats; this practice is sustainable while population levels are low and time is permitted for regrowth of natural vegetation; conversely, where these conditions do not exist, the practice can have disastrous consequences for the environment . soil degradation - damage to the land's productive capacity because of poor agricultural practices such as the excessive use of pesticides or fertilizers, soil compaction from heavy equipment, or erosion of topsoil, eventually resulting in reduced ability to produce agricultural products. soil erosion - the removal of soil by the action of water or wind, compounded by poor agricultural practices, deforestation, overgrazing, and desertification. ultraviolet (UV) radiation - a portion of the electromagnetic energy emitted by the sun and naturally filtered in the upper atmosphere by the ozone layer; UV radiation can be harmful to living organisms and has been linked to increasing rates of skin cancer in humans. water-born diseases - those in which the bacteria survive in, and is transmitted through, water; always a serious threat in areas with an untreated water supply.
Environment - international agreements	This entry separates country participation in international environmental agreements into two levels - party to and signed but not ratified. Agreements are listed in alphabetical order by the abbreviated form of the full name.
Environmental agreements	This information is presented in Appendix C: Selected International Environmental Agreements, which includes the name, abbreviation, date opened for signature, date entered into force, objective, and parties by category.
Ethnic groups	This entry provides a rank ordering of ethnic groups starting with the largest and normally includes the percent of total population.
Exchange rates	This entry provides the official value of a country's monetary unit at a given date or over a given period of time, as expressed in units of local currency per US dollar and as determined by international market forces or official fiat.
Executive branch	This entry includes several subfields. Chief of state includes the name and title of the titular leader of the country who represents the state at official and ceremonial functions but may not be involved with the day-to-day activities of the government. Head of government includes the name and title of the top administrative leader who is designated to manage the day-to-day activities of the government. For example, in the UK, the monarch is the chief of state, and the prime minister is the head of government. In the US, the president is both the chief of state and the head of government. Cabinet includes the official name for this body of high-ranking advisers and the method for selection of members. Elections includes the nature of election process or accession to power, date of the last election, and date of the next election. Election results includes the percent of vote for each candidate in the last election.
Exports	This entry provides the total US dollar amount of exports on an f.o.b. (free on board) basis.
Exports - commodities	This entry provides a rank ordering of exported products starting with the most important; it sometimes includes the percent of total dollar value.
Exports - partners	This entry provides a rank ordering of trading partners starting with the most important; it sometimes includes the percent of total dollar value.
Fiscal year	This entry identifies the beginning and ending months for a country's accounting period of 12 months, which often is the calendar year but which may begin in any month. All yearly references are for the calendar year (CY) unless indicated as a noncalendar fiscal year (FY).
Flag description	This entry provides a written flag description produced from actual flags or the best information available at the time the entry was written. The flags of independent states are used by their dependencies unless there is an officially recognized local flag. Some disputed and other areas do not have flags.
Flag graphic	Most versions of the Factbook include a color flag at the beginning of the country profile. The flag graphics were produced from actual flags or the best information available at the time of preparation. The flags of independent states are used by their dependencies unless there is an officially recognized local flag. Some disputed and other areas do not have flags.
GDP	This entry gives the gross domestic product (GDP) or value of all final goods and services produced within a nation in a given year. GDP dollar estimates in the Factbook are derived from purchasing power parity (PPP) calculations. See the note on GDP methodology for more information.
GDP methodology	In the Economy section, GDP dollar estimates for all countries are derived from purchasing power parity (PPP) calculations rather than from conversions at official currency exchange rates. The PPP method involves the use of standardized international dollar price weights, which are applied to the quantities of final goods and services produced in a given economy. The data derived from the PPP method provide the best available starting point for comparisons of economic strength and well-being between countries. The division of a GDP estimate in domestic currency by the corresponding PPP estimate in dollars gives the PPP conversion rate. Whereas PPP estimates for OECD countries are quite reliable, PPP estimates for developing countries are often rough approximations. Most of the GDP estimates are based on extrapolation of PPP numbers published by the UN International Comparison Program (UNICP) and by Professors Robert Summers and Alan Heston of the University of Pennsylvania and their colleagues. In contrast, the currency exchange rate method involves a variety of international and domestic financial forces that often have little relation to domestic output. In developing countries with weak currencies the exchange rate estimate of GDP in dollars is typically one-fourth to one-half the PPP estimate. Furthermore, exchange rates may suddenly go up or down by 10% or more because of market forces or official fiat whereas real output has remained unchanged. On 12 January 1994, for example, the 14 countries of the African Financial Community (whose currencies are tied to the French franc) devalued their currencies by 50%. This move, of course, did not cut the real output of these countries by half. One important caution: the proportion of, say, defense expenditures as a percentage of GDP in local currency accounts may differ substantially from the proportion when GDP accounts are expressed in PPP terms, as, for example, when an observer tries to estimate the dollar level of Russian or Japanese military expenditures. Note: the numbers for GDP and other economic data can not be chained together from successive volumes of the Factbook because of changes in the US dollar measuring rod, revisions of data by statistical agencies, use of new or different sources of information, and changes in national statistical methods and practices.
GDP - composition by sector	This entry gives the percentage contribution of agriculture, industry, and services to total GDP.
GDP - per capita	This entry shows GDP on a purchasing power parity basis divided by population as of 1 July for the same year.
GDP - real growth rate	This entry gives GDP growth on an annual basis adjusted for inflation and expressed as a percent.
Geographic coordinates	This entry includes rounded latitude and longitude figures for the purpose of finding the approximate geographic center of an entity and is based on the Gazetteer of Conventional Names, Third Edition, August 1988, US Board on Geographic Names and on other sources.
Geographic names	This information is presented in Appendix F: Cross-Reference List of Geographic Names. It includes a listing of various alternate names, former names, local names, and regional names referenced to one or more related Factbook entries. Spellings are normally, but not always, those approved by the US Board on Geographic Names (BGN). Alternate names and additional information are included in parentheses.
Geography	This category includes the entries dealing with the natural environment and the effects of human activity.
Geography - note	This entry includes miscellaneous geographic information of significance not included elsewhere.
GNP	Gross national product (GNP) is the value of all final goods and services produced within a nation in a given year, plus income earned by its citizens abroad, minus income earned by foreigners from domestic production. The Factbook, following current practice, uses GDP rather than GNP to measure national production. However, the user must realize that in certain countries net remittances from citizens working abroad may be important to national well-being.
Government	This category includes the entries dealing with the system for the adoption and administration of public policy.
Government type	This entry gives the basic form of government (e.g., republic, constitutional monarchy, federal republic, parliamentary democracy, military dictatorship).
Government - note	This entry includes miscellaneous government information of significance not included elsewhere.
Gross domestic product	see GDP
Gross national product	see GNP
Gross world product	see GWP
GWP	This entry gives the gross world product (GWP) or aggregate value of all final goods and services produced worldwide in a given year.
Heliports	This entry gives the total number of established helicopter takeoff and landing sites (which may or may not have fuel or other services).
Highways	This entry states the total length of the highway system and the length of the paved and unpaved parts.
HIV/AIDS � adult prevalence rate	This entry gives an estimate of the percentage of adults (aged 15-49) living with HIV/AIDS. The adult prevalence rate is calculated by dividing the estimated number of adults living with HIV/AIDS at yearend by the total adult population at yearend.
HIV/AIDS � deaths	This entry gives an estimate of the number of adults and children who died of AIDS during a given calendar year.
HIV/AIDS � people living with HIV/AIDS	This entry gives an estimate of all people (adults and children) alive at yearend with HIV infection, whether or not they have developed symptoms of AIDS.
Household income or consumption by percentage share	Data on household income or consumption come from household surveys, the results adjusted for household size. Nations use different standards and procedures in collecting and adjusting the data. Surveys based on income will normally show a more unequal distribution than surveys based on consumption. The quality of surveys is improving with time, yet caution is still necessary in making inter-country comparisons.
Hydrographic data codes	see Data codes
Illicit drugs	This entry gives information on the five categories of illicit drugs - narcotics, stimulants, depressants (sedatives), hallucinogens, and cannabis. These categories include many drugs legally produced and prescribed by doctors as well as those illegally produced and sold outside of medical channels. Cannabis (Cannabis sativa) is the common hemp plant, which provides hallucinogens with some sedative properties, and includes marijuana (pot, Acapulco gold, grass, reefer), tetrahydrocannabinol (THC, Marinol), hashish (hash), and hashish oil (hash oil). Coca (mostly Erythroxylum coca) is a bush with leaves that contain the stimulant used to make cocaine. Coca is not to be confused with cocoa, which comes from cacao seeds and is used in making chocolate, cocoa, and cocoa butter. Cocaine is a stimulant derived from the leaves of the coca bush. Depressants (sedatives) are drugs that reduce tension and anxiety and include chloral hydrate, barbiturates (Amytal, Nembutal, Seconal, phenobarbital), benzodiazepines (Librium, Valium), methaqualone (Quaalude), glutethimide (Doriden), and others (Equanil, Placidyl, Valmid). Drugs are any chemical substances that effect a physical, mental, emotional, or behavioral change in an individual. Drug abuse is the use of any licit or illicit chemical substance that results in physical, mental, emotional, or behavioral impairment in an individual. Hallucinogens are drugs that affect sensation, thinking, self-awareness, and emotion. Hallucinogens include LSD (acid, microdot), mescaline and peyote (mexc, buttons, cactus), amphetamine variants (PMA, STP, DOB), phencyclidine (PCP, angel dust, hog), phencyclidine analogues (PCE, PCPy, TCP), and others (psilocybin, psilocyn). Hashish is the resinous exudate of the cannabis or hemp plant (Cannabis sativa). Heroin is a semisynthetic derivative of morphine. Mandrax is a trade name for methaqualone, a pharmaceutical depressant. Marijuana is the dried leaf of the cannabis or hemp plant (Cannabis sativa). Methaqualone is a pharmaceutical depressant, referred to as mandrax in Southwest Asia and Africa. Narcotics are drugs that relieve pain, often induce sleep, and refer to opium, opium derivatives, and synthetic substitutes. Natural narcotics include opium (paregoric, parepectolin), morphine (MS-Contin, Roxanol), codeine (Tylenol with codeine, Empirin with codeine, Robitussan AC), and thebaine. Semisynthetic narcotics include heroin (horse, smack), and hydromorphone (Dilaudid). Synthetic narcotics include meperidine or Pethidine (Demerol, Mepergan), methadone (Dolophine, Methadose), and others (Darvon, Lomotil). Opium is the brown, gummy exudate of the incised, unripe seedpod of the opium poppy. Opium poppy (Papaver somniferum) is the source for the natural and semisynthetic narcotics. Poppy straw concentrate is the alkaloid derived from the mature, dried opium poppy. Qat (kat, khat) is a stimulant from the buds or leaves of Catha edulis that is chewed or drunk as tea. Quaaludes is the North American slang term for methaqualone, a pharmaceutical depressant. Stimulants are drugs that relieve mild depression, increase energy and activity, and include cocaine (coke, snow, crack), amphetamines (Desoxyn, Dexedrine), ephedrine, ecstasy (clarity, essence, doctor, Adam), phenmetrazine (Preludin), methylphenidate (Ritalin), and others (Cylert, Sanorex, Tenuate).

Imports - partners	This entry provides a rank ordering of trading partners starting with the most important; it sometimes includes the percent of total dollar value.
Independence	For most countries, this entry gives the date that sovereignty was achieved and from which nation, empire, or trusteeship. For the other countries, the date given may not represent "independence" in the strict sense, but rather some significant nationhood event such as the traditional founding date or the date of unification, federation, confederation, establishment, fundamental change in the form of government, or state succession. Dependent areas include the notation "none" followed by the nature of their dependency status. Also see the Terminology note.
Industrial production growth rate	This entry gives the annual percentage increase in industrial production (includes manufacturing, mining, and construction).
Industries	This entry provides a rank ordering of industries starting with the largest by value of annual output.
Infant mortality rate	This entry gives the number of deaths of infants under one year old in a given year per 1,000 live births in the same year. This rate is often used as an indicator of the level of health in a country.
Inflation rate (consumer prices)	This entry furnishes the annual percent change in consumer prices compared with the previous year’s consumer prices.
Internet country code	This entry includes the two-letter codes maintained by the International Organization for Standardization (ISO) in the ISO 3166 Alpha-2 list and used by the Internet Assigned Numbers Authority (IANA) to establish country-coded top-level domains (ccTLDs).
Internet Service Providers (ISPs)	This entry supplies the number of Internet Service Providers within a country. An ISP is defined as a company that provides access to the Internet.
Internet users	This entry gives the number of users within a country that access the Internet. Statistics vary from country to country and may include users who access the Internet at least several times a week to those who access it only once within a period of several months.
International disputes	see Disputes - international
International organization participation	This entry lists in alphabetical order by abbreviation those international organizations in which the subject country is a member or participates in some other way.
International organizations	This information is presented in Appendix B: International Organizations and Groups which includes the name, abbreviation, date established, aim, and members by category.
Introduction	This category includes one entry, Background.
Irrigated land	This entry gives the number of square kilometers of land area that is artificially supplied with water.
Judicial branch	This entry contains the name(s) of the highest court(s) and a brief description of the selection process for members.
Labor force	This entry contains the total labor force figure.
Labor force - by occupation	This entry contains a rank ordering of component parts of the labor force by occupation.
Land boundaries	This entry contains the total length of all land boundaries and the individual lengths for each of the contiguous border countries.
Land use	This entry contains the percentage shares of total land area for three different types of land use: arable land - land cultivated for crops that are replanted after each harvest like wheat, maize, and rice; permanent crops - land cultivated for crops that are not replanted after each harvest like citrus, coffee, and rubber; includes land under flowering shrubs, fruit trees, nut trees, and vines, but excludes land under trees grown for wood or timber; other - any land not arable or under permanent crops; includes permanent meadows and pastures, forests and woodlands, built-on areas, roads, barren land, etc.
Languages	This entry provides a rank ordering of languages starting with the largest and sometimes includes the percent of total population speaking that language.
Legal system	This entry contains a brief description of the legal system's historical roots, role in government, and acceptance of International Court of Justice (ICJ) jurisdiction.
Legislative branch	This entry contains information on the structure (unicameral, bicameral, tricameral), formal name, number of seats, and term of office. Elections includes the nature of election process or accession to power, date of the last election, and date of the next election. Election results includes the percent of vote and/or number of seats held by each party in the last election.
Life expectancy at birth	This entry contains the average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future. The entry includes total population as well as the male and female components. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures.
Literacy	This entry includes a definition of literacy and Census Bureau percentages for the total population, males, and females. There are no universal definitions and standards of literacy. Unless otherwise specified, all rates are based on the most common definition - the ability to read and write at a specified age. Detailing the standards that individual countries use to assess the ability to read and write is beyond the scope of the Factbook. Information on literacy, while not a perfect measure of educational results, is probably the most easily available and valid for international comparisons. Low levels of literacy, and education in general, can impede the economic development of a country in the current rapidly changing, technology-driven world.
Location	This entry identifies the country's regional location, neighboring countries, and adjacent bodies of water.
Map references	This entry includes the name of the Factbook reference map on which a country may be found. The entry on Geographic coordinates may be helpful in finding some smaller countries.
Maritime claims	This entry includes the following claims, the definitions of which are excerpted from the Law of the Sea (LOS) Convention, which alone contains the full and definitive descriptions: contiguous zone - according to the LOS Convention (Article 33), this is a zone contiguous to a coastal State's territorial sea, over which it may exercise the control necessary to: prevent infringement of its customs, fiscal, immigration, or sanitary laws and regulations within its territory or territorial sea; punish infringement of the above laws and regulations committed within its territory or territorial sea; the contiguous zone may not extend beyond 24 nautical miles from the baselines from which the breadth of the territorial sea is measured (e.g. the US has claimed a 12-mile contiguous zone in addition to its 12-mile territorial sea) continental shelf - the LOS Convention (Article 76) defines the continental shelf of a coastal State as comprising the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance; the continental margin comprises the submerged prolongation of the landmass of the coastal State, and consists of the seabed and subsoil of the shelf, the slope and the rise; it does not include the deep ocean floor with its oceanic ridges or the subsoil thereof exclusive economic zone (EEZ) - the LOS Convention (Part V) defines the EEZ as a zone beyond and adjacent to the territorial sea in which a coastal State has: sovereign rights for the purpose of exploring and exploiting, conserving and managing the natural resources, whether living or non-living, of the waters superjacent to the seabed and of the seabed and its subsoil, and with regard to other activities for the economic exploitation and exploration of the zone, such as the production of energy from the water, currents, and winds; jurisdiction with regard to the establishment and use of artificial islands, installations, and structures; marine scientific research; the protection and preservation of the marine environment; the outer limit of the exclusive economic zone shall not exceed 200 nautical miles from the baselines from which the breadth of the territorial sea is measured exclusive fishing zone - while this term is not used in the LOS Convention, some States (e.g. the United Kingdom) have chosen not to claim an EEZ, but rather to claim jurisdiction over the living resources off their coast; in such cases, the term exclusive fishing zone is often used territorial sea - the sovereignty of a coastal State extends beyond its land territory and internal waters to an adjacent belt of sea, described as the territorial sea in the LOS Convention (Part II); this sovereignty extends to the air space over the territorial sea as well as its underlying seabed and subsoil; every State has the right to establish the breadth of its territorial sea up to a limit not exceeding 12 nautical miles
Median Age	This entry is the age that divides a population into two numerically equal groups; that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population. Currently, the median age ranges from a low of about 15 in Uganda and Gaza Strip to 40 or more in several European countries and Japan. See the entry for “Age structure” for the importance of a younger versus an older age structure and, by implication, a lower versus a higher median age.
Merchant marine	Merchant marine may be defined as all ships engaged in the carriage of goods; or all commercial vessels (as opposed to all nonmilitary ships), which excludes tugs, fishing vessels, offshore oil rigs, etc.; or a grouping of merchant ships by nationality or register. This entry contains information in two subfields - total and ships by type. Total includes the total number of ships (1,000 GRT or over), total DWT for those ships, and total GRT for those ships. DWT or dead weight tonnage is the total weight of cargo, plus bunkers, stores, etc. that a ship can carry when immersed to the appropriate load line. GRT or gross register tonnage is a figure obtained by measuring the entire sheltered volume of the ship available for cargo and passengers and converting it to tons on the basis of 100 cubic feet per ton; there is no stable relationship between GRT and DWT. Ships by type includes a listing of barge carriers, bulk cargo ships, cargo ships, chemical tankers, combination bulk carriers, combination ore/oil carriers, container ships, liquefied gas tankers, livestock carriers, multifunctional large-load carriers, petroleum tankers, passenger ships, passenger/cargo ships, railcar carriers, refrigerated cargo ships, roll-on/roll-off cargo ships, short-sea passenger ships, specialized tankers, and vehicle carriers. A captive register is a register of ships maintained by a territory, possession, or colony primarily or exclusively for the use of ships owned in the parent country; it is also referred to as an offshore register, the offshore equivalent of an internal register. Ships on a captive register will fly the same flag as the parent country, or a local variant of it, but will be subject to the maritime laws and taxation rules of the offshore territory. Although the nature of a captive register makes it especially desirable for ships owned in the parent country, just as in the internal register, the ships may also be owned abroad. The captive register then acts as a flag of convenience register, except that it is not the register of an independent state. A flag of convenience register is a national register offering registration to a merchant ship not owned in the flag state. The major flags of convenience (FOC) attract ships to their registers by virtue of low fees, low or nonexistent taxation of profits, and liberal manning requirements. True FOC registers are characterized by having relatively few of the registered ships actually owned in the flag state. Thus, while virtually any flag can be used for ships under a given set of circumstances, an FOC register is one where the majority of the merchant fleet is owned abroad. It is also referred to as an open register. A flag state is the nation in which a ship is registered and which holds legal jurisdiction over operation of the ship, whether at home or abroad. Maritime legislation of the flag state determines how a ship is crewed and taxed and whether a foreign-owned ship may be placed on the register. An internal register is a register of ships maintained as a subset of a national register. Ships on the internal register fly the national flag and have that nationality but are subject to a separate set of maritime rules from those on the main national register. These differences usually include lower taxation of profits, use of foreign nationals as crewmembers, and, usually, ownership outside the flag state (when it functions as an FOC register). The Norwegian International Ship Register and Danish International Ship Register are the most notable examples of an internal register. Both have been instrumental in stemming flight from the national flag to flags of convenience and in attracting foreign-owned ships to the Norwegian and Danish flags. A merchant ship is a vessel that carries goods against payment of freight; it is commonly used to denote any nonmilitary ship but accurately restricted to commercial vessels only. A register is the record of a ship's ownership and nationality as listed with the maritime authorities of a country; also, it is the compendium of such individual ships' registrations. Registration of a ship provides it with a nationality and makes it subject to the laws of the country in which registered (the flag state) regardless of the nationality of the ship's ultimate owner.
Military	This category includes the entries dealing with a country's military structure, manpower, and expenditures.
Military branches	This entry lists the names of the ground, naval, air, marine, and other defense or security forces.
Military expenditures - dollar figure	This entry gives current military expenditures in US dollars; the figure is calculated by multiplying the estimated defense spending in percentage terms by the gross domestic product (GDP) calculated on an exchange rate basis *not* purchasing power parity (PPP) terms. Dollar figures for military expenditures should be treated with caution because of different price patterns and accounting methods among nations, as well as wide variations in the strength of their currencies.
Military expenditures - percent of GDP	This entry gives current military expenditures as an estimated percent of gross domestic product (GDP).
Military manpower - availability	This entry gives the total numbers of males and females age 15-49 and assumes that every individual is fit to serve.
Military manpower - fit for military service	This entry gives the number of males and females age 15-49 fit for military service. This is a more refined measure of potential military manpower availability which tries to correct for the health situation in the country and reduces the maximum potential number to a more realistic estimate of the actual number fit to serve.
Military manpower - military age	This entry gives the minimum age at which an individual may volunteer for military service or be subject to conscription.
Military manpower - reaching military age annually	This entry gives the number of draft-age males and females entering the military manpower pool in any given year and is a measure of the availability of draft-age young adults.
Military - note	This entry includes miscellaneous military information of significance not included elsewhere.
Money figures	All money figures are expressed in contemporaneous US dollars unless otherwise indicated.
National holiday	This entry gives the primary national day of celebration - usually independence day.
Nationality	This entry provides the identifying terms for citizens - noun and adjective.
Natural Gas - consumption	This entry is the total quantity of natural gas consumed in cubic meters. The discrepancy between the quantity of natural gas produced and/or imported and the quantity consumed and/or exported is due to the omission of stock changes and other complicating factors.
Natural Gas - exports	This entry is the total quantity of natural gas exported in cubic meters.
Natural Gas - imports	This entry is the total quantity of natural gas imported in cubic meters.
Natural Gas - production	This entry is the total quantity of natural gas produced in cubic meters. The discrepancy between the quantity of natural gas produced and/or imported and the quantity consumed and/or exported is due to the omission of stock changes and other complicating factors.
Natural Gas - proved reserves	This entry is the stock of proved reserves of natural gas in cubic meters (cu. m.). Proved reserves are those quantities of natural gas, which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.
Natural hazards	This entry lists potential natural disasters.
Natural resources	This entry lists a country's mineral, petroleum, hydropower, and other resources of commercial importance.
Net migration rate	This entry includes the figure for the difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (e.g., 3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (e.g., -9.26 migrants/1,000 population). The net migration rate indicates the contribution of migration to the overall level of population change. High levels of migration can cause problems such as increasing unemployment and potential ethnic strife (if people are coming in) or a reduction in the labor force, perhaps in certain key sectors (if people are leaving).
Oil - consumption	This entry is the total oil consumed in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.
Oil - exports	This entry is the total oil exported in barrels per day (bbl/day), including both crude oil and oil products.
Oil - imports	This entry is the total oil imported in barrels per day (bbl/day), including both crude oil and oil products.
Oil - production	This entry is the total oil produced in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.
Oil - proved reserves	This entry is the stock of proved reserves of crude oil in barrels (bbl). Proved reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.
People	This category includes the entries dealing with the characteristics of the people and their society.
People - note	This entry includes miscellaneous demographic information of significance not included elsewhere.
Personal Names - Capitalization	The Factbook uses all uppercase letters for personal names by which the subject is usually referred to in various media. An example is President Vicente FOX Quesada of Mexico. Members of royal families are usually referred by other than their family name (King and Prime Minister FAHD bin Abd al-Aziz Al Saud of Saudi Arabia, Queen BEATRIX of the Netherlands, or King PHUMIPHON Adunyadet of Thailand). Some Asians are referred to by the first element of their name - also their surname, such as President NO Muh-hyun of South Korea.
Personal Names - Spelling	The romanization of personal names in the Factbook normally follows the same transliteration system used by the US Board on Geographic Names for spelling place names. At times, however, a foreign leader expressly indicates a preference for, or the media or official documents regularly use, a romanized spelling that differs from the transliteration derived from the US Government standard. In such cases, the Factbook uses the alternative spelling.
Personal Names - Titles	The Factbook capitalizes any valid title (or short form of it) immediately preceding a person's name. A title standing alone is lowercased. Examples: President PUTIN and President BUSH are chiefs of state. In Russia, the president is chief of state and the premier is the head of the government, while in the US, the president is both chief of state and head of government.
Petroleum	See “Oil” entries
Petroleum products	See “Oil” entries
Pipelines	This entry gives the lengths and types of pipelines for transporting products like natural gas, crude oil, or petroleum products.
Political parties and leaders	This entry includes a listing of significant political organizations and their leaders.
Political pressure groups and leaders	This entry includes a listing of organizations with leaders involved in politics, but not standing for legislative election.
Population	This entry gives an estimate from the US Bureau of the Census based on statistics from population censuses, vital statistics registration systems, or sample surveys pertaining to the recent past and on assumptions about future trends. The total population presents one overall measure of the potential impact of the country on the world and within its region. Note: starting with the 1993 Factbook, demographic estimates for some countries (mostly African) have explicitly taken into account the effects of the growing impact of the HIV/AIDS epidemic. These countries are currently: The Bahamas, Benin, Botswana, Brazil, Burkina Faso, Burma, Burundi, Cambodia, Cameroon, Central African Republic, Democratic Republic of the Congo, Republic of the Congo, Cote d'Ivoire, Ethiopia, Gabon, Ghana, Guyana, Haiti, Honduras, Kenya, Lesotho, Malawi, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Swaziland, Tanzania, Thailand, Togo, Uganda, Zambia, and Zimbabwe.
Population below poverty line	National estimates of the percentage of the population lying below the poverty line are based on surveys of sub-groups, with the results weighted by the number of people in each group. Definitions of poverty vary considerably among nations. For example, rich nations generally employ more generous standards of poverty than poor nations.
Population growth rate	The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative. The growth rate is a factor in determining how great a burden would be imposed on a country by the changing needs of its people for infrastructure (e.g., schools, hospitals, housing, roads), resources (e.g., food, water, electricity), and jobs. Rapid population growth can be seen as threatening by neighboring countries.
Ports and harbors	This entry lists the major ports and harbors selected on the basis of overall importance to each country. This is determined by evaluating a number of factors (e.g., dollar value of goods handled, gross tonnage, facilities, military significance).
Radio broadcast stations	This entry includes the total number of AM, FM, and shortwave broadcast stations.
Railways	This entry states the total route length of the railway network and of its component parts by gauge: broad, dual, narrow, standard, and other.
Reference maps	This section includes world and regional maps.
Religions	This entry includes a rank ordering of religions by adherents starting with the largest group and sometimes includes the percent of total population.
Sex ratio	This entry includes the number of males for each female in five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually it could cause unrest among young adult males who are unable to find partners.
Suffrage	This entry gives the age at enfranchisement and whether the right to vote is universal or restricted.
Telephone numbers	All telephone numbers in the Factbook consist of the country code in brackets, the city or area code (where required) in parentheses, and the local number. The one component that is not presented is the international access code, which varies from country to country. For example, an international direct dial telephone call placed from the US to Madrid, Spain, would be as follows: 011 [34] (1) 577-xxxx, where 011 is the international access code for station-to-station calls; 01 is for calls other than station-to-station calls, [34] is the country code for Spain, (1) is the city code for Madrid, 577 is the local exchange, and xxxx is the local telephone number. An international direct dial telephone call placed from another country to the US would be as follows: international access code + [1] (202) 939-xxxx, where [1] is the country code for the US, (202) is the area code for Washington, DC, 939 is the local exchange, and xxxx is the local telephone number.

Terminology	Due to the highly structured nature of the Factbook database, some collective generic terms have to be used. For example, the word Country in the Country name entry refers to a wide variety of dependencies, areas of special sovereignty, uninhabited islands, and other entities in addition to the traditional countries or independent states. Military is also used as an umbrella term for various civil defense, security, and defense activities in many entries. The Independence entry includes the usual colonial independence dates and former ruling states as well as other significant nationhood dates such as the traditional founding date or the date of unification, federation, confederation, establishment, or state succession that are not strictly independence dates. Dependent areas have the nature of their dependency status noted in this same entry.
Terrain	This entry contains a brief description of the topography.
Total fertility rate	This entry gives a figure for the average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to a given fertility rate at each age. The total fertility rate is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. This indicator shows the potential for population growth in the country. High rates will also place some limits on the labor force participation rates for women. Large numbers of children born to women indicate large family sizes that might limit the ability of the families to feed and educate their children.
Transnational Issues	This category includes only two entries at the present time - Disputes - international and Illicit drugs - that deal with current issues going beyond national boundaries.
Transportation	This category includes the entries dealing with the means for movement of people and goods.
Transportation - note	This entry includes miscellaneous transportation information of significance not included elsewhere.
Unemployment rate	This entry contains the percent of the labor force that is without jobs. Substantial underemployment might be noted.
Waterways	This entry gives the total length and individual names of navigable rivers, canals, and other inland bodies of water.
Years	All year references are for the calendar year (CY) unless indicated as fiscal year (FY). The calendar year is an accounting period of 12 months from 1 January to 31 December. The fiscal year is an accounting period of 12 months other than 1 January to 31 December.
Note: Information for the US and US dependencies was compiled from material in the public domain and does not represent Intelligence Community estimates.
