Gini Index of Income Inequality

The Gini Index is a measure of income inequality ranging from 0 to 1. A value of 0 represents perfect income equality (everyone has the same income); a value of 1 represents complete inequality (one person has all the income and others have none). Warehouse data is updated twice a year and is as up to date as the data source when published.
