The ranking was is based on data from the International Monetary Fund.
The magazine ranked the world’s countries according to their gross domestic product (GDP) based on purchasing power parity (PPP) per capita.
The PPP takes into account the relative cost of living and the inflation rates of the countries to compare living standards among the different nations.
Most of the countries populating the top of this ranking are under authoritarian regimes where corruption is rampant. This a big deterrent to foreign investors, even if some of those countries have huge amounts of natural resources.
The GDP per capita listed represents the amount of wealth produced and is expressed in international dollars.
