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; 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. Ships

by type includes a listing of barge carriers, bulk cargo ships, cargo

ships, combination bulk carriers, combination ore/oil carriers,

container ships, intermodal ships, liquefied gas tankers, livestock

carriers, multifunction large-load carriers, oil tankers, passenger

ships, passenger-cargo ships, railcar carriers, refrigerated cargo

ships, roll-on/roll-off cargo ships, short-sea passenger ships,

specialized tankers, tanker tug-barges, 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 crew members, 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 military-type 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. The figure 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 capital: This entry gives the location of the seat of

government.

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 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 reducing the labor force, perhaps in

certain key sectors (if people are leaving).

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.

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 taken

into account the effects of the growing incidence of AIDS infections.

In 1998 these countries are Botswana, Brazil, Burkina Faso, Burma,

Burundi, Cambodia, Cameroon, Central African Republic, Democratic

Republic of the Congo, Republic of the Congo, Cote d'Ivoire, Ethiopia,

Guyana, Haiti, Honduras, Kenya, Lesotho, Malawi, Namibia, Nigeria,

Rwanda, South Africa, Swaziland, Tanzania, Thailand, Uganda, Zambia,

and Zimbabwe.

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. Also known as growth rate or average

annual rate of growth. 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.

Radios: This entry gives the total number of radio receivers.

Railways: This entry includes the total length of the railway network

and component parts by gauge: broad, dual, narrow, standard, and

other.

Reference maps: This section includes world, regional, and special or

current interest maps.

Religions: This entry includes a rank ordering of religions starting

with the largest 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. The sex ratio

at birth for the World is 1.06 (1998 est.).

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.

Telephones: This entry gives the total number of subscribers.

Television-broadcast stations: This entry gives the total number of

separate broadcast stations plus any repeater stations.

Televisions: This entry gives the total number of television sets.

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. The National Capital

entry includes the first-order administrative seat for ''nations'' or

independent states as well as dependencies and other Factbook

entities.

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 capacity of the families to 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

movement of people or material.
