The Gini index is the most widely used measure of inequality. It looks at the distribution of a nation’s income or wealth, where 0 represents complete equality and 100 total inequality.
Using the most recent figures, South Africa, Namibia and Haiti are among the most unequal countries in terms of income distribution – based on the Gini index estimates from the World Bank – while Ukraine, Slovenia and Norway rank as the most equal nations in the world.

The ratio takes the richest 10% of the population’s share of gross national income (GNI) and divides it by the poorest 40% of the population’s share. This measure has become popular as more income inequality research focuses on the growing divide between the richest and poorest in society.
