Over the past 40 years, most poor neighborhoods in the U.S. have only gotten poorer. Now, a series of new maps by Justin Palmer, a designer at Github, details exactly where these neighborhoods are—and just how much worse off they’ve gotten.
Each map tracks how the poverty rate in census tracts within 10 miles of a major U.S. city has changed between 1970 and 2010. Green arrows represent a decline in poverty; red arrows indicate an increase. Longer arrows show greater change, and thick arrows mean the area has a high population density.
