Gross domestic product (GDP) per capita (per person) is calculated as GDP in absolute values divided on size of countries population for the corresponding period of time.

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.

Population, as referred to the System of National Accounts 1993, is the annual average number of persons present in the economic territory of a country, including institutional population.

Absolute values or Common currency (US$) estimates are computed by the secretariat using purchasing power parities (PPPs), which are the rates of currency conversion that equalise the purchasing power of different currencies. PPPs, and not exchange rates, should be used in international comparisons of GDP and its components.
