The Gini Coefficient is a way to measure equity and is derived from the Lorenz curve.
The Gini coefficient is defined graphically as a ratio of two surfaces involving the summation of all vertical deviations between the Lorenz curve and the perfect equality line (A) divided by the difference between the perfect equality and perfect inequality lines (A+B).
The Lorenz Curve is a graphical representation of the proportionality of a distribution. It represents a probability distribution of statistical values, and is often associated with income distribution calculations and commonly used in the analysis of inequality.

It has lost its position mainly to the Microsoft Internet Information Services (IIS) since March 2006 and to the .NET platform used by some large blog providers, but it still serves roughly around 50% servers worldwide.
