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 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 five 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; permanent pastures - land permanently used for herbaceous forage crops; forests and woodland - land under dense or open stands of trees; other - any land type not specifically mentioned above, such as urban areas, roads, desert, 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: contiguous zone, continental shelf, exclusive economic zone, exclusive fishing zone, extended fishing zone, none (usually for a landlocked country), other (unique maritime claims like Libya's Gulf of Sidra Closing Line or North Korea's Military Boundary Line), and territorial sea. The proximity of neighboring states may prevent some national claims from being extended the full distance.

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,
