s,
for example, when an observer tries to estimate the dollar level of
Russian or Japanese military expenditures.
Note: the numbers for GDP and other economic data can 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. For statistical series
on GDP and other economic variables, see the Handbook of International
Economic Statistics available from the same sources as The World
Factbook.

GDP-composition by sector: This entry gives the percentage
contribution of agriculture, industry, and services to total GDP.

GDP-per capita: 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.

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 Gazetteer of
Conventional Names, Third Edition, August 1988, US Board on Geographic
Names and on other sources.

Geographic names: This information is presented in Appendix H:
Cross-Reference List of Geographic Names which indicates where various
geographic names-including alternate names, former names, political or
geographical portions of larger entities, and the location of all US
Foreign Service Posts-can be found in The World Factbook. Spellings
are normally, but not always, those approved by the US Board on
Geographic Names (BGN). Alternate names are included in parentheses,
while additional information is included in brackets.

Geography: This category includes the entries dealing with the natural
environment and the effects of human activity.

information of significance not included elsewhere.

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 uses GDP rather than GNP to measure
national production.

Government: This category includes the entries dealing with the system
