Counties wtih Some Other Race Alone Population Ranked by Percent (Continental US and Alaska)

The percentage of people who self-classified themselves as "Some Other Race" is much higher along the southwestern United States. There could be a few reasons for this clustering of responses for "some other race." First of all, the American southwest is home to large swaths of Native American populations. They may still wish to refer to themselves as members of their original tribe, and thus mark the "Some Other Race" category (even instead of the Native American box). Additionally, the American West is known for being liberal, and marking "Some Other Race" category even if you fit into a different category could be a form of political statement.
