The countries are ranked by the World Bank and the International Monetary Fund (IMF).
They are ranked according to their Gross Domestic Product (GDP), based on purchasing power parity 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. The GDP per capita listed represents the amount of wealth produced by the countries in 2015, in dollars.
These are the 10 poorest countries in the world:
1. Central African Republic - GDP per capita $639
