The Poorest Countries in the World

There are two standard methods of measuring the wealth of countries and how rich or poor its inhabitants are. The measure most often used is Gross Domestic Product (GDP), which represents the size of a country’s economy. A refinement of this is per-capita GDP, which is a measure of the average welfare and affluence, or poverty, of residents of a country. However, GDP and per-capita GDP are less useful when comparing economies across national boundaries – which one must do to determine the poorest countries in the world – because GDP is expressed in a country’s local currency.
The measure that most economists prefer is GDP at purchasing power parity. GDP (PPP) compares 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 countries, rather than using just exchange rates, which may distort the real differences in income.
