State Prison Admission Trends 1925-1982

Pamela E. Oliver

July 11, 2011

These graphs are calculated from National Prison Statistics data compiled by Patrick A. Langan for his 1991 report "Race of Prisoners Admitted to State and Federal Institutions, 1926-86," United States Department of Justice. Washington, DC: Bureau of Justice Statistics and distributed through the Inter-University Consortium for Political and Social Research at the University of Michigan. I have corrected some obvious errors in these data which could be identified from numbers that were orders of magnitude wrong and have interpolated where data from adjacent years made interpolation reasonable.

In this era, disparity ratios exceeding 100 arise from very small Black populations for which the rates are highly unstable.
