What is the 'Gini Index?
​
The Gini index or Gini coefficient is a statistical measure of distribution developed by the Italian statistician Corrado Gini in 1912.
It is often used as a gauge of economic inequality, measuring income distribution among a population. The coefficient ranges from 0 (or 0%) to 1 (or 100%), with 0 representing perfect equality and 1 representing perfect inequality. Values over 1 are theoretically possible due to negative income or wealth.
​
A country in which every resident has the same income would have an income Gini coefficient of 0. A country in one resident earned all the income, while everyone else earned nothing, would have an income Gini coefficient of 1.
