Roughly..
If Black Americans are close to 40 million..
50% or less will be males, so 20 million brehs..
Those born after 1965-1985 will be the older generation that were there from the start to the 2nd generation born 1980s till today..if one in 5 brehs spits even casually, then were talking millions.
Those with serious rapper ambitions and dreams would be 1 in 10 perhaps, so close to 2 million. And this is minus the females..
