After years of being besieged by useless infographics, we almost forgot how arresting data can be when displayed compellingly. Rich Block Poor Block has been around since at least last month, but we just discovered the site ourselves via Upworthy, the Chris Hughes-backed aggregator founded by Eli Pariser and Peter Koechley, alums from MoveOn and The Onion.

The site showcases median household income collected from the American Community Survey from 2007 through 2011 along Google Maps. You can look up any neighborhood in America, but of course we checked out our own blocks first. Witness the income level drop as you move East from Park Slope to Prospect Heights to Crown Heights–or the red outlier of the Farragut Houses in Dumbo below.

In case you’re wondering: Union Square? Green as a valley.
