Definitions

GWP

This entry gives the gross world product (GWP) or aggregate value of all final goods and services produced worldwide in a given year.

Piracy

Piracy is defined by the 1982 United Nations Convention on the Law of the Sea as any illegal act of violence, detention, or depredation directed against a ship, aircraft, persons, or property in a place outside the jurisdiction of any State. Such criminal acts committed in the territorial waters of a littoral state are generally considered to be armed robbery against ships. Information on piracy may be found, where applicable, in the Transportation - note.

Investment (gross fixed)

This entry records total business spending on fixed assets, such as factories, machinery, equipment, dwellings, and inventories of raw materials, which provide the basis for future production. It is measured gross of the depreciation of the assets, i.e., it includes investment that merely replaces worn-out or scrapped capital.

Time difference

This entry is expressed in The World Factbook in two ways. First, it is stated as the difference in hours between the capital of an entity and Coordinated Universal Time (UTC) during Standard Time. Additionally, the difference in time between the capital of an entity and that observed in Washington, D.C. is also provided. Note that the time difference assumes both locations are simultaneously observing Standard Time or Daylight Saving Time.

Entities

Some of the independent states, dependencies, areas of special sovereignty, and governments included in this publication are not independent, and others are not officially recognized by the US Government. "Independent state" refers to a people politically organized into a sovereign state with a definite territory. "Dependencies" and "areas of special sovereignty" refer to a broad category of political entities that are associated in some way with an independent state. "Country" names used in the table of contents or for page headings are usually the short-form names as approved by the US Board on Geographic Names and may include independent states, dependencies, and areas of special sovereignty, or other geographic entities. There are a total of 267 separate geographic entities in The World Factbook that may be categorized as follows:

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.

Greenwich Mean Time (GMT)

The mean solar time at the Greenwich Meridian, Greenwich, England, with the hours and days, since 1925, reckoned from midnight. GMT is now a historical term having been replaced by UTC on 1 January 1972. See Coordinated Universal Time.

Acronyms

An acronym is an abbreviation coined from the initial letter of each successive word in a term or phrase. In general, an acronym made up solely from the first letter of the major words in the expanded form is rendered in all capital letters (NATO from North Atlantic Treaty Organization; an exception would be ASEAN for Association of Southeast Asian Nations). In general, an acronym made up of more than the first letter of the major words in the expanded form is rendered with only an initial capital letter (Comsat from Communications Satellite Corporation; an exception would be NAM from Nonaligned Movement). Hybrid forms are sometimes used to distinguish between initially identical terms (ICC for International Chamber of Commerce and ICCt for International Criminal Court).

Country map

Most versions of the Factbook provide a country map in color. The maps were produced from the best information available at the time of preparation. Names and/or boundaries may have changed subsequently.

Rare earth elements

Rare earth elements or REEs are 17 chemical elements that are critical in many of today's high-tech industries. They include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, and yttrium. Typical applications for REEs include batteries in hybrid cars, fiber optic cables, flat panel displays, and permanent magnets, as well as some defense and medical products.

Daylight Saving Time (DST)

This entry is included for those entities that have adopted a policy of adjusting the official local time forward, usually one hour, from Standard Time during summer months. Such policies are most common in mid-latitude regions.

Time zones

Ten countries (Australia, Brazil, Canada, Indonesia, Kazakhstan, Mexico, New Zealand, Russia, Spain, and the United States) and the island of Greenland observe more than one official time depending on the number of designated time zones within their boundaries. An illustration of time zones throughout the world and within countries can be seen in the Standard Time Zones of the World map included in the Reference Maps section of The World Factbook.

Telephone numbers

All telephone numbers in The World 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.

Stateless person

Statelessness is the condition whereby an individual is not considered a national by any country. Stateless people are denied basic rights, such as access to employment, housing, education, healthcare, and pensions, and they may be unable to vote, own property, open a bank account, or legally register a marriage or birth. They may also be vulnerable to arbitrary treatment and human trafficking. In at least 30 states, women cannot pass their nationality on to their children. In these countries, if a child's father is foreign, stateless, or absent, the child usually becomes stateless. Estimates of the number of stateless people are inherently imprecise because few countries have procedures to identify them; the UN approximates that there are 12 million stateless people worldwide. Stateless people are counted in a country’s overall population figure if they have lived there for a year.

Personal Names - Titles

The Factbook capitalizes any valid title (or short form of it) immediately preceding a person's name. A title standing alone is not capitalized. Examples: President PUTIN and President OBAMA are chiefs of state. In Russia, the president is chief of state and the premier is the head of the government, while in the US, the president is both chief of state and head of government.

Appendixes

This section includes Factbook-related material by topic.

Coordinated Universal Time (UTC)

UTC is the international atomic time scale that serves as the basis of timekeeping for most of the world. The hours, minutes, and seconds expressed by UTC represent the time of day at the Prime Meridian (0º longitude) located near Greenwich, England as reckoned from midnight. UTC is calculated by the Bureau International des Poids et Measures (BIPM) in Sevres, France. The BIPM averages data collected from more than 200 atomic time and frequency standards located at about 50 laboratories worldwide. UTC is the basis for all civil time with the Earth divided into time zones expressed as positive or negative differences from UTC. UTC is also referred to as "Zulu time." See the Standard Time Zones of the World map included with the Reference Maps.

Years

All year references are for the calendar year (CY) unless indicated as fiscal year (FY). The calendar year is an accounting period of 12 months from 1 January to 31 December. The fiscal year is an accounting period of 12 months other than 1 January to 31 December.

Personal Names - Capitalization

The Factbook capitalizes the surname or family name of individuals for the convenience of our users who are faced with a world of different cultures and naming conventions. The need for capitalization, bold type, underlining, italics, or some other indicator of the individual's surname is apparent in the following examples: MAO Zedong, Fidel CASTRO Ruz, George W. BUSH, and TUNKU SALAHUDDIN Abdul Aziz Shah ibni Al-Marhum Sultan Hisammuddin Alam Shah. By knowing the surname, a short form without all capital letters can be used with confidence as in President Castro, Chairman Mao, President Bush, or Sultan Tunku Salahuddin. The same system of capitalization is extended to the names of leaders with surnames that are not commonly used such as Queen ELIZABETH II. For Vietnamese names, the given name is capitalized because officials are referred to by their given name rather than by their surname. For example, the president of Vietnam is Tran Duc LUONG. His surname is Tran, but he is referred to by his given name - President LUONG.

Geographic names

This information is presented in Appendix F: Cross Reference List of Geographic Names. It includes a listing of various alternate names, former names, local names, and regional names referenced to one or more related Factbook entries. Spellings are normally, but not always, those approved by the US Board on Geographic Names (BGN). Alternate names and additional information are included in parentheses.

Population pyramid

A population pyramid illustrates the age and sex structure of a country’s population and may provide insights about political and social stability, as well as economic development.The population is distributed along the horizontal axis, with males shown on the left and females on the right. The male and female populations are broken down into 5-year age groups represented as horizontal bars along the vertical axis, with the youngest age groups at the bottom and the oldest at the top. The shape of the population pyramid gradually evolves over time based on fertility, mortality, and international migration trends.
Some distinctive types of population pyramids are:
- A youthful distribution has a broad base and narrow peak and is characterized by a high proportion of children and low proportion of the elderly. This population distribution results from high fertility, high mortality, low life expectancy, and high population growth. It is typical of developing countries where female education and contraceptive use are low and health care and sanitation are poor.
- A transitional distribution is caused by declining fertility and mortality rates, increasing life expectancy, and slowing population growth. The population has a larger proportion of working-age people relative to children and the elderly and produces a barrel-shaped pyramid, where the mid-section bulges and the base and top are narrower. The large proportion of working-age people can create a “demographic bonus” if it is educated and productively employed.
- A mature distribution has fairly balanced proportions of the population in the child, working-age, and elderly age groups and will gradually form an inverted triangle population pyramid as population growth continues to fall or ceases and the proportion of older people increases. Low fertility, low mortality, and high life expectancy - made possible by the availability of advanced healthcare, family planning, sanitation, and education - lead to aging populations in industrialized countries.

Petroleum

See entries under Refined petroleum products.

Weights and Measures

This information is presented in Appendix G: Weights and Measures and includes mathematical notations (mathematical powers and names), metric interrelationships (prefix; symbol; length, weight, or capacity; area; volume), and standard conversion factors.

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.

Environmental agreements

This information is presented in Appendix C: Selected International Environmental Agreements, which includes the name, abbreviation, date opened for signature, date entered into force, objective, and parties by category.

Date of information

In general, information available as of January in a given year is used in the preparation of the printed edition.

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.

Reference maps

This section includes world and regional maps.

Diplomatic representation

The US Government has diplomatic relations with 190 independent states, including 188 of the 193 UN members (excluded UN members are Bhutan, Cuba, Iran, North Korea, and the US itself). In addition, the US has diplomatic relations with 2 independent states that are not in the UN, the Holy See and Kosovo, as well as with the EU.

Money figures

All money figures are expressed in contemporaneous US dollars unless otherwise indicated.

Personal Names - Spelling

The romanization of personal names in the Factbook normally follows the same transliteration system used by the US Board on Geographic Names for spelling place names. At times, however, a foreign leader expressly indicates a preference for, or the media or official documents regularly use, a romanized spelling that differs from the transliteration derived from the US Government standard. In such cases, the Factbook uses the alternative spelling.

Petroleum products

See entries under Refined petroleum products.

Gross national product

Abbreviations

This information is included in Appendix A: Abbreviations, which includes all abbreviations and acronyms used in the Factbook, with their expansions.

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.
