Gini coefficient - measure of statistical dispersion of income distribution

Wikipedia: Gini coefficient - "Wealthy countries such as Sweden can show a low Gini coefficient for disposable income of 0.31 thereby appearing equal, yet have very high Gini coefficient for wealth of 0.79 to 0.86 thereby suggesting an extremely unequal wealth distribution in its society."

The Gini coefficient (sometimes expressed as a Gini ratio or a normalized Gini index) (/dʒini/ jee-nee) is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents, and is the most commonly used measure of inequality.

The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income). A Gini coefficient of zero expresses perfect equality, where all values are the same (for example, where everyone has an exactly equal income).

The Gini Coefficient: Calculating the Gini Coefficient

Graphical representation of the Gini coefficient The graph shows that the Gini coefficient is equal to the area marked A divided by the sum of the areas marked A and B, that is, Gini = A / (A + B). It is also equal to 2A and to 1 - 2B due to the fact that A + B = 0.5 (since the axes scale from 0 to 1).
