It would be interesting to see the county with the highest white-black mixed race %.
I would say the counties along the "Black Belt" from Mississippi to North Carolina would have highest rates of black-white mix.
Doubt it. Mississippi has one of the lowest percentages of mixed-race people, and there's still widespread disapproval of black-white dating and marriage throughout much of the South. Things have changed a lot in the last 40 years, but they haven't changed that much.
Exactly. Of the top 50 counties with the highest percentages of mixed-race people, less than half (24) even are over 1% black.
