America’s most diverse counties. Source: Atlantic Cities blog.
San Jose, according to the calculations of Jed Kolko, is the most racially diverse metropolitan region in the country: 35% white, 31% Asian, 28% Hispanic, 3% multi-racial and 2% black. New York ranks second. The map above displays diversity for counties across the United States, with greater “diversity” characterized by smaller percentages for the largest ethnic group.
By this definition, the West and the South are the most diverse regions in the country, due to the presence of large minorities of Hispanics in the West and African-Americans in the South. The least diverse part of the country is New England, which, coincidentally, is one of the most liberal. Draw your own conclusions as to what that means.
