query: What does GDP stand for?
passage: Gross domestic product
Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a period of time, often annually GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing differences in living standards between nations.
passage: List of countries by GDP sector composition
The figures are based on nominal GDP and GDP (PPP) estimates and sector composition ratios provided by the CIA World Factbook at market or government official exchange rates with figures in trillions of United States dollars.
