Mississippi actually has the highest percentage of black people in the country.
Stats like that are why I get a bit squeamish when people write off ever visiting the state. White people here are, by and large, pretty racist, but the Mississippi Delta is one of the most interesting places in the country to visit. Birthplace of the blues, and food that tastes better than anything I've eaten. Stop by Clarksdale, MS and eat at Morgan Freeman's restaurant (and see the crossroads where Robert Johnson allegedly sold his soul to the devil to learn the blues); take a drive around the cotton fields; talk to older black people about their history here.
Whenever people trash Mississippi, they really mean "white Mississippi," which has been nothing but a blight on the country. But black Mississippi is a treasure that's created some beautiful contributions to America.
