For decades in the US, the incarceration rate for African Americans has been much higher than for whites, a racial disparity
the US Attorney General Eric Holder has described as "shameful".
Mr Holder unveiled a policy shift that will mean the US locks up fewer people convicted of non-violent, drugs offences.
The state that locks up the highest percentage of black men is Wisconsin.
The national average is 6.7%, but in Wisconsin it's 12.8% -
more than three percentage points higher than the second-placed state, Oklahoma.
