    • … Gini coefficient is commonly used as a measure of inequality of income or wealth.[1] For OECD countries, in the late 2000s, considering the effect of taxes and transfer payments, the income Gini coefficient ranged between 0.24 to 0.49, with Slovenia the lowest and Chile the highest.[2] The countries in Africa had the highest pre-tax Gini coefficients in 2008-2009, with South Africa the world's highest at 0.7.[3][4] The global income inequality Gini coefficient in 2005, for all human beings taken together, has been estimated to be between 0.61 and 0.68 by various sources.[5][6]

      There are some issues in interpreting a Gini coefficient. The same value may result from many different distribution curves. The demographic structure should be taken into account. Countries with an aging population, or with a baby boom, experience an increasing pre-tax Gini coefficient even if real income distribution for working adults remain constant. Scholars have devised over a dozen variants of the Gini coefficient.[7][8][9]
