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 145,000 Inuits
of Russia, Alaska, Canada, and Greenland in international
environmental issues; a General Assembly 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.
Waterborne diseases - those in which bacteria survive in, and are
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 This information is presented in <a
href = "../appendix/appendix-c.html"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 an ordered listing 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. The International
Organization for Standardization (ISO) 4217 alphabetic currency code
for the national medium of exchange is presented in parenthesis.
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 merchandise
exports on an f.o.b. (free on board) basis. These figures are
calculated on an exchange rate basis, i.e., not in purchasing power
parity (PPP) terms.
Exports - commodities
This entry provides a listing of the highest-valued exported
products; 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.
F
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.
Freshwater withdrawal (domestic/industrial/agricultural)
This entry provides the annual quantity of water in cubic kilometers
removed from available sources for use in any purpose. Water
drawn-off is not necessarily entirely consumed and some portion may
be returned for further use downstream. Domestic sector use refers
to water supplied by public distribution systems. Note that some of
this total may be used for small industrial and/or limited
agricultural purposes. Industrial sector use is the quantity of
water used by self-supplied industries not connected to a public
distribution system. Agricultural sector use includes water used for
irrigation and livestock watering, and does not account for
agriculture directly dependent on rainfall. Included are figures for
total annual water withdrawal and per capita water withdrawal.
G
GDP (official exchange rate)
This entry gives the gross domestic product (GDP) or value of all
final goods and services produced within a nation in a given year. A
nation's GDP at official exchange rates (OER) is the
home-currency-denominated annual GDP figure divided by the bilateral
average US exchange rate with that country in that year. The measure
is simple to compute and gives a precise measure of the value of
output. Many economists prefer this measure when gauging the
economic power an economy maintains vis-a-vis its neighbors, judging
that an exchange rate captures the purchasing power a nation enjoys
in the international marketplace. Official exchange rates, however,
can be artificially fixed and/or subject to manipulation - resulting
in claims of the country having an under- or over-valued currency -
and are not necessarily the equivalent of a market-determined
exchange rate. Moreover, even if the official exchange rate is
market-determined, market exchange rates are frequently established
by a relatively small set of goods and services (the ones the
country trades) and may not capture the value of the larger set of
goods the country produces. Furthermore, OER-converted GDP is not
well suited to comparing domestic GDP over time, since
appreciation/depreciation from one year to the next will make the
OER GDP value rise/fall regardless of whether
home-currency-denominated GDP changed.
GDP (purchasing power parity)
This entry gives the gross domestic product (GDP) or value of all
final goods and services produced within a nation in a given year. A
nation's GDP at purchasing power parity (PPP) exchange rates is the
sum value of all goods and services produced in the country valued
at prices prevailing in the United States. This is the measure most
economists prefer when looking at per-capita welfare and when
comparing living conditions or use of resources across countries.
The measure is difficult to compute, as a US dollar value has to be
assigned to all goods and services in the country regardless of
whether these goods and services have a direct equivalent in the
United States (for example, the value of an ox-cart or non-US
military equipment); as a result, PPP estimates for some countries
are based on a small and sometimes different set of goods and
services. In addition, many countries do not formally participate in
the World Bank's PPP project that calculates these measures, so the
resulting GDP estimates for these countries may lack precision. For
many developing countries, PPP-based GDP measures are multiples of
the official exchange rate (OER) measure. The differences between
the OER- and PPP-denominated GDP values for most of the wealthy
industrialized countries are generally much smaller.
GDP - composition by sector
This entry gives the percentage contribution of agriculture,
industry, and services to total GDP. The distribution will total
less than 100 percent if the data are incomplete.
GDP - per capita (PPP)
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.
GDP methodology
In the Economy category, GDP dollar estimates for countries are
reported both on an official exchange rate (OER) and a purchasing
power parity (PPP) basis. Both measures contain information that is
useful to the reader. 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 probably provide the
best available starting point for comparisons of economic strength
and well-being between countries. In contrast, the currency exchange
rate method involves a variety of international and domestic
financial forces that may not capture the value of domestic output.
Whereas PPP estimates for OECD countries are quite reliable, PPP
estimates for developing countries are often rough approximations.
In developing countries with weak currencies, the exchange rate
estimate of GDP in dollars is typically one-fourth to one-half the
PPP estimate. Most of the GDP estimates for developing countries 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. GDP derived using the OER method should be used for the
purpose of calculating the share of items such as exports, imports,
military expenditures, external debt, or the current account
balance, because the dollar values presented in the Factbook for
these items have been converted at official exchange rates, not at
PPP. One should use the OER GDP figure to calculate the proportion
of, say, Chinese defense expenditures in GDP, because that share
will be the same as one calculated in local currency units.
Comparison of OER GDP with PPP GDP may also indicate whether a
currency is over- or under-valued. If OER GDP is smaller than PPP
GDP, the official exchange rate may be undervalued, and vice versa.
However, there is no strong historical evidence that market exchange
rates move in the direction implied by the PPP rate, at least not in
the short- or medium-term. Note: the numbers for GDP and other
economic data should 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.
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.
GWP
This entry gives the gross world product (GWP) or aggregate value of
all final goods and services produced worldwide in a given year.
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 locations provided in the Geographic Names
Server (GNS), maintained by the National Geospatial-Intelligence
Agency on behalf of the US Board on Geographic Names.

Government type
This entry gives the basic form of government. Definitions of the
major governmental terms are as follows. (Note that for some
countries more than one definition applies.):
Absolute monarchy - a form of government where the monarch rules
unhindered, i.e., without any laws, constitution, or legally
organized opposition.
Anarchy - a condition of lawlessness or political disorder brought
about by the absence of governmental authority.
Authoritarian - a form of government in which state authority is
imposed onto many aspects of citizens' lives.
Commonwealth - a nation, state, or other political entity founded on
law and united by a compact of the people for the common good.
Communist - a system of government in which the state plans and
controls the economy and a single - often authoritarian - party
holds power; state controls are imposed with the elimination of
private ownership of property or capital while claiming to make
progress toward a higher social order in which all goods are equally
shared by the people (i.e., a classless society).
Confederacy (Confederation) - a union by compact or treaty between
states, provinces, or territories, that creates a central government
with limited powers; the constituent entities retain supreme
authority over all matters except those delegated to the central
government.
Constitutional - a government by or operating under an authoritative
document (constitution) that sets forth the system of fundamental
laws and principles that determines the nature, functions, and
limits of that government.
Constitutional democracy - a form of government in which the
sovereign power of the people is spelled out in a governing
constitution.
Constitutional monarchy - a system of government in which a monarch
is guided by a constitution whereby his/her rights, duties, and
responsibilities are spelled out in written law or by custom.
Democracy - a form of government in which the supreme power is
retained by the people, but which is usually exercised indirectly
through a system of representation and delegated authority
periodically renewed.
Democratic republic - a state in which the supreme power rests in
the body of citizens entitled to vote for officers and
representatives responsible to them.
Dictatorship - a form of government in which a ruler or small clique
wield absolute power (not restricted by a constitution or laws).
Ecclesiastical - a government administrated by a church.
Emirate - similar to a monarchy or sultanate, but a government in
which the supreme power is in the hands of an emir (the ruler of a
Muslim state); the emir may be an absolute overlord or a sovereign
with constitutionally limited authority.
Federal (Federation) - a form of government in which sovereign power
is formally divided - usually by means of a constitution - between a
central authority and a number of constituent regions (states,
colonies, or provinces) so that each region retains some management
of its internal affairs; differs from a confederacy in that the
central government exerts influence directly upon both individuals
as well as upon the regional units.
Federal republic - a state in which the powers of the central
government are restricted and in which the component parts (states,
colonies, or provinces) retain a degree of self-government; ultimate
sovereign power rests with the voters who chose their governmental
representatives.
Islamic republic - a particular form of government adopted by some
Muslim states; although such a state is, in theory, a theocracy, it
remains a republic, but its laws are required to be compatible with
the laws of Islam.
Maoism - the theory and practice of Marxism-Leninism developed in
China by Mao Zedong (Mao Tse-tung), which states that a continuous
revolution is necessary if the leaders of a communist state are to
keep in touch with the people.
Marxism - the political, economic, and social principles espoused by
19th century economist Karl Marx; he viewed the struggle of workers
as a progression of historical forces that would proceed from a
class struggle of the proletariat (workers) exploited by capitalists
(business owners), to a socialist "dictatorship of the proletariat,"
to, finally, a classless society - Communism.
Marxism-Leninism - an expanded form of communism developed by Lenin
from doctrines of Karl Marx; Lenin saw imperialism as the final
stage of capitalism and shifted the focus of workers' struggle from
developed to underdeveloped countries.
Monarchy - a government in which the supreme power is lodged in the
hands of a monarch who reigns over a state or territory, usually for
life and by hereditary right; the monarch may be either a sole
absolute ruler or a sovereign - such as a king, queen, or prince -
with constitutionally limited authority.
Oligarchy - a government in which control is exercised by a small
group of individuals whose authority generally is based on wealth or
power.
Parliamentary democracy - a political system in which the
legislature (parliament) selects the government - a prime minister,
premier, or chancellor along with the cabinet ministers - according
to party strength as expressed in elections; by this system, the
government acquires a dual responsibility: to the people as well as
to the parliament.
Parliamentary government (Cabinet-Parliamentary government) - a
government in which members of an executive branch (the cabinet and
its leader - a prime minister, premier, or chancellor) are nominated
to their positions by a legislature or parliament, and are directly
responsible to it; this type of government can be dissolved at will
by the parliament (legislature) by means of a no confidence vote or
the leader of the cabinet may dissolve the parliament if it can no
longer function.
Parliamentary monarchy - a state headed by a monarch who is not
actively involved in policy formation or implementation (i.e., the
exercise of sovereign powers by a monarch in a ceremonial capacity);
true governmental leadership is carried out by a cabinet and its
head - a prime minister, premier, or chancellor - who are drawn from
a legislature (parliament).
Presidential - a system of government where the executive branch
exists separately from a legislature (to which it is generally not
accountable).
Republic - a representative democracy in which the people's elected
deputies (representatives), not the people themselves, vote on
legislation.
Socialism - a government in which the means of planning, producing,
and distributing goods is controlled by a central government that
theoretically seeks a more just and equitable distribution of
property and labor; in actuality, most socialist governments have
ended up being no more than dictatorships over workers by a ruling
elite.
Sultanate - similar to a monarchy, but a government in which the
supreme power is in the hands of a sultan (the head of a Muslim
state); the sultan may be an absolute ruler or a sovereign with
constitutionally limited authority.
Theocracy - a form of government in which a Deity is recognized as
the supreme civil ruler, but the Deity's laws are interpreted by
ecclesiastical authorities (bishops, mullahs, etc.); a government
subject to religious authority.
Totalitarian - a government that seeks to subordinate the individual
to the state by controlling not only all political and economic
matters, but also the attitudes, values, and beliefs of its
population.
