^^ infact the AA growth rates were lower than the whites, so this MIRACULOUS growth rate was not at all. The AA growth rate can't be above average if their percentage of population dropped from 19% to 12.6%
You're confusing natural growth rate and overall growth rate.
Overall growth rate includes European migration to the United States and natural increase.
African-Americans could only rely upon their natural increase since importation of enslaved Africans ceased in 1807. Even in that circumstance, their population growth relative to White America was quite high.
