Click to find out what income inequality is like in your community

ProPublica has a good rundown on a much-discussed study by the Congressional Budget Office showing that over the past three decades the income of the highest-paid Americans has soared while the income of others has grown much more modestly.

Now they’ve taken it to the next level with an online app which allows you to compare income inequality among 818 of the largest counties in America.

The app uses the Gini index, a statistical measure that ranges from zero (a community in which every citizen has precisely the same income) to one (the opposite extreme, in which one person receives literally all of the income).

Check out your county’s income inequality here. You can also access the raw data for yourself through the 2010 Census’ American Community Survey.
