List of countries by GDP

There are three lists of countries of the world sorted by their gross domestic product (GDP) (the value of all final goods and services produced within a nation in a given year). The GDP dollar estimates given on this page are derived from Purchasing Power Parity (PPP) calculations. Using a PPP basis is arguably more useful when comparing generalized differences in living standards on the whole between nations because PPP takes into account the relative cost of living and the inflation rates of the countries, rather than using just exchange rates which may distort the real differences in income.
