A geography professor at the University of Cincinnati repurposed NASA maps to show the changing racial diversity of every neighborhood in the continental United States.
Tomasz Stepinski, who previously served as a longtime researcher at the Lunar and Planetary Institute in Houston, Texas, applied NASA mapmaking techniques to 20 years of data collected by the U.S. Census Bureau to build one of the most detailed racial-diversity maps ever created.
The zoomable map shows at a glance how the racial composition of neighborhoods changed between 1990 and 2010.
