Here's something people from South Florida (and people looking to move to South Florida) will find interesting.
It's called RichBlocksPoorBlocks.com
It's an interactive map that shows how rich or poor every neighborhood in America is.
You type in an address, city, and/or state, and the site zooms to the location. It shows a color-coded map of neighborhood income.
Here's Miami, Ft. Lauderdale, and West Palm Beach for example.
