Income inequality is often measured by the Gini index, named for Italian statistician Corrado Gini, who developed it in 1912. It measures income distribution on a scale of zero to one, with zero meaning everyone has the same income and one indicating that a single person has all the income. The higher the number, the greater the amount of income inequality.

Here's a state-by-state look at the Gini rating measurements by household in 1979 compared with 2012, the latest year for which figures are available from the U.S. Census Bureau. The "increase" column represents the percentage increase in income inequality.
