what it says on the tin, in 1865 Mississippi and South Carolina were already slave majority (55% and 57%) while Alabama, Florida, Georgia, and Louisiana all had slave populations over 40% (45%, 44%, 44% and 47%) this doesn't cover any free black populations, any ways with-out freedom and the mass movement of blacks out of the slave to the north and west starting in the 1870s, would more of the south become black or even slave majority? would all of the CSA over all become black majority? if so how long might that take? if not why not?
