Notes, Abbreviations, Definitions There have been some significant changes in this edition. Czechoslovakia has been superseded by the Czech Republic and Slovakia. Eritrea gained independence from Ethiopia. The name of the Ivory Coast has been changed to Cote d'Ivoire and the Vatican City became the Holy See. New entries include Location, Map references, Abbreviation (often substituted for the country name), and Digraph (two-letter country code). Names is a new entry which includes long and short forms of both conventional and local names of countries as well as any former names. Most diacritical marks have been omitted. The electronic files used to produce the Factbook have been restructured into a database. As a result, the formats of some entries in this edition have been changed. Additional changes will occur in the 1994 Factbook. Irrigated land is a new entry with the data separate from the Land use entry. The Disputes entry is now International disputes. The GNP/GDP entry was renamed National Product and the per capita and real growth rate data placed in separate entries. Similar changes were made in the Population and Diplomatic Representation entries.

Changes that have been reported but not yet acted on by BGN are noted. Area: 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). Comparative areas are based on total area equivalents. Most entities are compared with the entire US or one of the 50 states. The smaller entities are compared with Washington, DC (178 km2, 69 miles 2) or The Mall in Washington, DC (0.59 km2, 0.23 miles 2,146 acres). Birth rate: The average annual number of births during a year per 1,000 population at midyear; also known as crude birth rate. Dates of information: In general, information available as of 1 January 1993 was used in the preparation of this edition. Population figures are estimates for 1 July 1993, with population growth rates estimated for calendar year 1993. Major political events have been updated through June 1993. Death rate: The average annual number of deaths during a year per l,000 population at midyear; also known as crude death rate. Digraphs: The digraph is a two-letter "country code'' that precisely identifies every entity without overlap, duplication, or omission. AF, for example, is the digraph for Afghanistan. It is a standardized geopolitical data element promulgated in the Federal Information Processing Standards Publication (FIPS) 10-3 by the National Bureau of Standards (US Department of Commerce) and maintained by the Office of the Geographer (US Department of State). The digraph 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. Diplomatic representation: The US Government has diplomatic relations with 180 nations. The US has diplomatic relations with 174 of the 182 UN members (excluding the Socialist Federal Republic of Yugoslavia whose status in the UN is unclear)--the exceptions are Angola, Bhutan, Cuba, Iran, Iraq, Macedonia, North Korea, and Vietnam. In addition, the US has diplomatic relations with 7 nations that are not in the UN-Andorra, Holy See, Kiribati, Nauru, Switzerland, Tonga, and Tuvalu. Economic aid: This entry refers to bilateral commitments of official development assistance (ODA), which is defined as government grants that are administered with the promotion of economic development and welfare of LDCs as their main objective and are concessional in character and contain a grant element of at least 25%, and other official flows (OOF) or transactions by the official sector whose main objective is other than development motivated or whose grant element is below the 25% threshold for ODA. OOF transactions include official export credits (such as Ex-Im Bank credits), official equity and portfolio investment, and debt reorganization by the official sector that does not meet concessional terms. Aid is considered to have been committed when agreements are initialed by the parties involved and constitute a formal declaration of intent. Entities: Some of the nations, dependent areas, areas of special sovereignty, and governments included in this publication are not independent, and others are not officially recognized by the US Government. "Nation'' refers to a people politically organized into a sovereign state with a definite territory. "Dependent area" refers to a broad category of political entities that are associated in some way with a nation. Names used for page headings are usually the short-form names as approved by the US Board on Geographic Names. There are 266 entities in The World Factbook that may be categorized as follows: NATIONS 182 UN members (excluding the Socialist Federal Republic of Yugoslavia whose status in the UN is unclear) 8 nations that are not members of the UN--Andorra, Holy See, Kiribati, Nauru, Serbia and Montenegro, Switzerland, Tonga, Tuvalu OTHER 1 Taiwan DEPENDENT AREAS 6 Australia--Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, Norfolk Island 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 1 Portugal--Macau 16 United Kingdom--Anguilla, Bermuda, British Indian Ocean Territory, British Virgin Islands, Cayman Islands, Falkland Islands, Gibraltar, Guernsey, Hong Kong, Jersey, Isle of Man, Montserrat, Pitcairn Islands, Saint Helena, South Georgia and the South Sandwich Islands, Turks and Caicos Islands 15 United States--American Samoa, Baker Island, Guam, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Islands, Navassa Island, Northern Mariana Islands, Trust Territory of the Pacific Islands (Palau), Palmyra Atoll, Puerto Rico, Virgin Islands, Wake Island MISCELLANEOUS 6 Antarctica, Gaza Strip, Paracel Islands, Spratly Islands, West Bank, Western Sahara OTHER ENTITIES 4 oceans--Arctic Ocean, Atlantic Ocean, Indian Ocean, Pacific Ocean 1 World 266 total note: The US Government does not recognize the four so-called independent homelands of Bophuthatswana, Ciskei, Transkei, and Venda in South Africa. Exchange rate: The value of a nation'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. Gross domestic product (GDP): The value of all goods and services produced domestically in a given year. Gross national product (GNP): The value of all goods and services produced domestically in a given year, plus income earned abroad, minus income earned by foreigners from domestic production. Gross world product (GWP): The aggregate value of all goods and services produced worldwide in a given year. GNP/GDP methodology: In the "Economy'' section, GNP/GDP dollar estimates for the OECD countries, the former Soviet republics, and the East European countries are derived from purchasing power parity (PPP) calculations rather than from conversions at official currency exchange rates. The PPP method normally involves the use of international dollar price weights, which are applied to the quantities of goods and services produced in a given economy. In addition to the lack of reliable data from the majority of countries, the statistician faces a major difficulty in specifying, identifying, and allowing for the quality of goods and services. The division of a PPP GNP/GDP estimate in dollars by the corresponding estimate in the local currency gives the PPP conversion rate. One thousand dollars will buy the same market basket of goods in the US as one thousand dollars--converted to the local currency at the PPP conversion rate-- will buy in the other country. GNP/GDP estimates for the LDCs, on the other hand, are based on the conversion of GNP/GDP estimates in local currencies to dollars at the official currency exchange rates. Because currency exchange rates depend on a variety of international and domestic financial forces that often have little relation to domestic output, use of these rates is less satisfactory for calculating GNP/GDP than the PPP method. 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. One additional caution: the proportion of, say, defense expenditures as a percent of GNP/GDP in local currency accounts may differ substantially from the proportion when GNP/GDP accounts are expressed in PPP terms, as, for example, when an observer estimates the dollar level of Russian or Japanese military expenditures; similar problems exist when components are expressed in dollars under currency exchange rate procedures. Finally, as academic research moves forward on the PPP method, we hope to convert all GNP/GDP estimates to this method in future editions of The World Factbook. Growth rate (population): The 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. Illicit drugs: There are 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 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 (Erythroxylon coca) is a bush, and the leaves contain the stimulant 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. Marijuana is the dried leaves of the cannabis or hemp plant (Cannabis sativa). 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 w/codeine, Empirin w/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 milky exudate of the incised, unripe seedpod of the opium poppy. Opium poppy (Papaver somniferum) is the source for many 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. Stimulants are drugs that relieve mild depression, increase energy and activity, and include cocaine (coke, snow, crack), amphetamines (Desoxyn, Dexedrine), phenmetrazine (Preludin), methylphenidate (Ritalin), and others (Cylert, Sanorex, Tenuate). Infant mortality rate: The number of deaths to infants under one year old in a given year per l,000 live births occurring in the same year. International disputes: This category 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 boundaries and maritime boundaries has been reviewed by the Department of State. References to other situations may also be included that are border or frontier relevant, such as resource disputes, geopolitical questions, or irredentist issues. However, inclusion does not necessarily constitute official acceptance or recognition by the US Government. Irrigated land: The figure refers to the number of km 2 that is artifically supplied with water. Land use: Human use of the land surface is categorized as arable land--land cultivated for crops that are replanted after each harvest (wheat, maize, rice); permanent crops--land cultivated for crops that are not replanted after each harvest (citrus, coffee, rubber); meadows and pastures--land permanently used for herbaceous forage crops; forest and woodland land--under dense or open stands of trees; and other--any land type not specifically mentioned above (urban areas, roads, desert). Leaders: The chief of state is the titular leader of the country who represents the state at official and ceremonial funcions but is not involved with the day- to-day activities of the government. The head of government is the administrative leader who manages the day-to-day activities of the government. 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. Life expectancy at birth: The average number of years to be lived by a group of people all born in the same year, if mortality at each age remains constant in the future. Literacy: There are no universal definitions and standards of literacy. Unless otherwise noted, 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 this publication. Maps: All maps will be available only in the printed version of The World Factbook for the foreseeable future. Maritime claims: The proximity of neighboring states may prevent some national claims from being extended the full distance. Merchant marine: All ships engaged in the carriage of goods. All commercial vessels (as opposed to all nonmilitary ships), which excludes tugs, fishing vessels, offshore oil rigs, etc.; also, a grouping of merchant ships by nationality or register. Captive register--A register of ships maintained by a territory, possession, or colony primarily or exclusively for the use of ships owned in the parent country; 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. Flag of convenience register--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 register 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 ships registered 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. Flag state--The nation in which a ship is registered and which holds legal jurisdiction over operation of the ship, whether at home or abroad. Differences in flag state maritime legislation determine how a ship is manned and taxed and whether a foreign-owned ship may be placed on the register. Internal register--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, manning by foreign nationals, 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 foreignowned ships to the Norwegian and Danish flags. Merchant ship--A vessel that carries goods against payment of freight; commonly used to denote any nonmilitary ship but accurately restricted to commercial vessels only. Register--The record of a ship's ownership and nationality as listed with the maritime authorities of a country; also, 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. Money figures: All are expressed in contemporaneous US dollars unless otherwise indicated. National product: The total output of goods and services in a country in a given year. See Gross domestic product (GDP), Gross national product (GNP), and GNP/GDP methodology. Net migration rate: The balance 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 (3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (-9.26 migrants/1,000 population). Population: Figures are estimates from the Bureau of the Census based on statistics from population censuses, vital registration systems, or sample surveys pertaining to the recent past, and on assumptions about future trends. Total fertility rate: 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. Years: All year references are for the calendar year (CY) unless indicated as fiscal year (FY). THE WORLD FACTBOOK 1993
