In 2010, high-income countries - that accounted for only 16 per cent of the world’s population - were estimated to generate 55 per cent of global income.1 Low-income countries created just above one per cent of global income even though they contained 72 per cent of global population. An average gross domestic product (GDP) per capita of $ 2,014 in sub-Saharan Africa in 2010 stood out against regional GDPs per capita of $ 27,640 in the European Union and $ 41,399 in North America. One way of measuring international inequality is to examine the Gini coefficient of per capita incomes of countries.
