DATA:

DOJ 2011
2.3 M people in prison
2.1 M men
208,300 women: 9%
Black men: 35.4%
White men: 32.9%
Hispanic men: 17.9%

US Ethnic Population
Black:men: ~6%
White men: ~33%
Hispanic men: ~8%

Prisoners per US Ethnic Population
Black men: 35.4/ 6 = 5.9
White men 32.9/ 40 = 0.82
Hispanic men 17.9/ 7 = 2.6

Data Analysis: Ratios
Black men to White men: 5.9/ 0.82 = 7.2
Black men to Hispanic men: 5.9/ 2.6 = 2.3
Hispanic men to White men: 2.6/ 0.82 = 3.2

In other words, based on their percent of the total US population, Black men are 7 times more likely to be in prison than White men. They are about 2 times as likely to be in prison as Hispanic men. Hispanic men  are about 3 times as likely to be in prison as White men.

One obvious explanation is based on the relatively low percentage of women (of any ethnicity) in prison. Women have approximately 10% of the testosterone of men [], and this is close to their portion in the prison population (9%).
