Today's maps are provided by Devinn Jani, who used 2010 U.S. Census data to give a portrait of racial distribution amongst the United States' population. Note that the scales aren't the same on all of the maps—each map has a different variance of representative data—so be mindful when comparing images as they each represent different statistical ranges.
Asian Population by County
Non-Hispanic White Population by County
Latino Population by County
African-American Population by County
Native American Population by County
You can see larger versions of the maps here. The website of the U.S. Census is, naturally, a good source of population data, so check it out here for more information.
