Gini coefficient

The Gini coefficient is a key ratio of income distribution in a country. The Gini coefficient is calculated from the lorentz curve and indicates how unequally incomes are distributed in a country.

A Gini coefficient of 0 % indicates a completely equal distribution of income in a country. A Gini coefficient of 100 % indicates a completely uneven income distribution in a country. The Gini coefficient can be used to compare the uniformity of income distribution across countries.
