ProPublica has an interesting online tool for you to give a whirl. Type in the zip code of your county (or parish) and it will tell you how it stands in terms of income inequality compared to other US counties. You can find it here. Just for information's sake, the county I live in, Cleveland, in Oklahoma shows 47 percent have more income inequality. That's about right. Oklahoma is in the middle on a lot of things. But just for grins I typed in a New Orleans address. Results: 99 percent of US counties have more income equality than Orleans Parish, LA. It does not get more stark than that. There is some discussion about the tool and its accuracy in the comments below.
