Tomasz Stepinski, a professor of geography at the University of Cincinnati, and his postdoctoral researcher Anna Dmowska who is now at Adam Mickiewicz University in Poznan, Poland, have produced a map of the United States that shows how the racial makeup of neighborhoods changed between 1990 and 2010. Users can zoom in to focus on a particular state, city, or even neighborhood. The maps are so detailed that information can be found for any 30-square-meter area in the country.
Professor Stepinski says that “people don’t realize that the United States is a diverse country but at the same time is still very segregated.”
