There are 4 black head coaches in the NBA of 32 teams so 4/32 or 12.5%

Remarkably close to the 13% black population of the US.

Kudos to the NBA for racial mirroring.

"Remarkably close to the 13% black population of the US." That's assuming the black pop. is, indeed, 13%. It seems like that number has been locked in for decades. Given how the demographics are changing in advertising, I suspect the real number is a good bit higher.
