Gross domestic product of countires in the world.

Countries of the world sorted by their gross domestic product (GDP) to values ​​of purchasing power parity (PPP), the sum of all goods and services produced by a country in a year, in relation to purchasing power parity (PPP .) This is an economic indicator introduced in the early nineties by the International Monetary Fund in a realistic way to compare living standards across countries, taking into account the per capita gross domestic product in terms of cost of living in each country.

The PPP is one of the most appropriate for comparing living standards that the gross domestic product per capita, as it takes into account changes in prices. This indicator eliminates money illusion linked to changes in exchange rates, so that an appreciation or depreciation of a currency will not change the purchasing power parity of a country, since the inhabitants of this country receive their wages and make purchases in the same currency. Ie, allows the exchange rates between currencies are such as to allow a coin has the same purchasing power anywhere in the world.
