Gross Domestic Product per Capita estimates are compiled according to the 1993 version of the System of National Accounts (SNA 1993) for all countries, except Turkey for which the 1968 SNA is still used. Common currency (US$) estimates are computed using purchasing power parities. Purchasing power parity (PPP) is the relative cost of the same representative basket of goods when valued at the domestic prices of two different countries. In other words, PPPs 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 real income.
