The 2003 CIA World Factbook. United States. Central Intelligence Agency
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
