The 13 Least Equal U.S. Cities
Income inequality is on the rise in the United States. Currently, the top 5 percent of U.S. households earn 22 percent of the aggregate income. Economists determine income equality by using the Gini index, which is measured on a scale ranging from 0 (total equality) to 1 (total inequality). These are the 13 U.S. metropolitan areas (pop. 300,000 or greater) with the highest estimated Gini measures, according to the U.S. Census Bureau's 2009 Current Population Survey. Also listed for each city are its 2009 median household incomes, as well as the share of income that goes to the top 5 percent of households.
