How vacant houses trace the boundaries of Baltimore’s black neighborhoods.
The map on the left shows one very tiny dot for each person living in Baltimore. White people are blue dots, blacks are green, Asians are red and Hispanics yellow.The map on the right shows the locations of Baltimore City’s 15,928 vacant buildings. Slide between the two maps and you’ll immediately notice that the wedge of white Baltimore, jutting down from the Northwest to the city center, is largely free of vacant buildings. But in the black neighborhoods on either side, empty buildings are endemic.
