One of D.C.'s unspoken truths is the burgeoning income equality gap. This divide can be broken down by neighborhood, and usually extends to crime, as the bulk of the city's homicides take place on its eastern end. Now, the Rich Blocks, Poor Blocks web tool allows you to visualize the gap.
Using data from 2006 to 2010, the map allows D.C. residents to see how they live as compared to those who live anywhere from a few blocks to a few miles away. The map isn't exclusive to D.C.; you can find one for pretty much every city in the U.S.
However, D.C. is far more divided than most of the other cities.
