Rich Blocks, Poor Blocks is an interactive map (created by Christopher Persaud, a data reporter for a bank website) showing the average income for every neighborhood in America. Type in your address, press search, and there you have it: Your city, shaded by income, according to data from an annual survey conducted by the Census Bureau. The greenest blocks–Census blocks, that is, not city blocks–signify the richest areas, typically bringing in an average household income of $100,000 or more a year. The reddest blocks are the poorest, with annual income somewhere around $20,000. All the rest get some shade of red or green, depending where they fall.
