Gini coefficient – Wikipedia, the free encyclopedia.

The Gini coefficient is usually defined mathematically based on the Lorenz curve (below). It can be thought of as the ratio of the area that lies between the line of equality and the Lorenz curve (marked ‘A’ in the diagram) over the total area under the line of equality (marked ‘A’ and ‘B’ in the diagram); i.e., G=A/(A+B).
