Maybe we’re not as diverse as we think we are.

John Paul DeWitt of CensusScope.org and the University of Michigan collaborated to pull together the data, and have a list of the top 10 most segregated cities in America. Despite what you may think, they’re not all in the South either.

But which city takes the cake? It’s Milwaukee, where 90 percent of African-Americans live in the inner city. Read Salon’s article to see what other urban areas made it onto the list.
