Trends in Wisconsin Imprisonment 2000-2014: Net Growth by Offense Group and Admission Types
This report examines the mix of offenses and admission types for prison admissions, prison releases, and numbers in prison 2000-2014. Wisconsin imprisonment rates declined slightly after the mid-2000s, but have risen since 2014. A detailed investigation of patterns of movement into and out of prison by offense and admission type (new sentence vs. revocation) shows that the decline after 2007 was small and the seeds of the rebound after 2012 in incarceration were present in the earlier trends. A steep decline in prison admissions for drug sentences and a decline in prison admissions for revocations after 2007 masked continuing slow rises in imprisonment from new commitments for other offenses, especially rape and murder. After 2012, a rise in revocations across offense groups and a rise in new commitments for drug offenses and several other categories of offenses led to a rise in the total imprisonment rate. The patterns by offense and admission type suggest that changes in violent crime rates and in sentence lengths within offense category play relatively little role in these trends. Total imprisonment trends are products of complex processes affecting different groups differently. Policy recommendations emphasize the drug war, sex offenders, and revocations for technical violations as the areas having the largest numerical impact on trends in imprisonment in Wisconsin. An appendix gives additional details about offenses and admission types. The report itself includes seven color graphs which show trends in imprisonment by offense and category of admission and the appendix includes another 22 color graphs that show the trends for each offense and the offense trends by admission type. The graphs attached to the report are printed two to a page. Alternate files include a separate copy of just the graphs printed one to a page for improved legibility, a copy of the text with no graphs and a shorter version without the appendix.Update 6/12/17 corrects an incorrect sentence about the proportion of rape offenders who entered on a revocation; includes two new graphs, one on the admission status of those in prison and admitted to prison by offense and another showing the offense mix of those in prison and admitted to prison; and adds tables to the appendix. An available spreadsheet provides the frequency data that are the basis of the graphs and tables.
