What is the effect of the Black prison rate on the Black unemployment rate

Well, some times you go looking for a good story but you are glad you did not find one. I recently speculated that the huge incarceration rate in the US would affect the Black unemployment rate.

Well it does affect the rate but only in a small way. We can estimate that the rate would be only about 1.5% higher due to the incarceration rate. In other words the rate would move from 15.2% to 16.7% due to people in jail.
