Class Inequality Increase

The Gini coefficient is a statistical measure frequently used by economists to represent the inequality of a distribution. Named after Italian statistician Corrado Gini, it is based on the differences between people in terms of income, wealth, or other measures of living standards. It provides a numerical indicator, typically ranging from 0 (perfect equality) to 1 (maximum inequality). The coefficient is formally defined as one-half of the average difference in a quantity between every pair of individuals, relative to the population's mean for that quantity.

The World Inequality Database (WID) is an open-access database that provides extensive historical and comparative data on the distribution of income and wealth, both within and between countries. Maintained by a network of international researchers, it aims to democratize access to economic data and inform public debate on inequality.

While assessing income differences between individuals is straightforward, quantifying inequality across an entire society requires specialized statistical tools. Among the various methods available, the rich/poor ratio and the Gini coefficient are two of the most commonly used measures to summarize and compare income distributions within populations.
