The Gini coefficient is used to measure income inequality across a population. It was developed by Corrado Gini, an Italian statistician, in 1912. It is measured on a scale of 0 to 1. Perfect inequality is represented by 1 and perfect equality is represented by 0. You can read about the Gini Coefficient – Definition, Calculation and India’s Rankings in the given link.
