Disparity ratio of Expected Black prison admission to actual white prison admission	3.6
*Expected Black Prison Admission Rate from black arrest rate if Prison/Arrest ratio equaled whites'

** Percent of total black-white difference due to prison/arrest ratio, i.e. for offense, difference between actual black imprisonment rate and that expected from arrests if the prison/arrest ratio were the same as for whites, divided by the total black-white difference in imprisonment (641.1).

*** Percent of total black-white difference attributed to differences in arrest rates, i.e., for offence, total difference minus that attributed to differences in the prison/arrest ratio, divided by the total black-white difference in imprisonment (641.1). These last two columns partition 100% of the total difference between blacks and whites in per capita imprisonment rates.
