In the first post in this series, I explored the large gap between the incarceration rates of Minnesota and Wisconsin. In the second, I discussed racial disparities in the incarcerated populations of the two states. The disparities in both states are wide, although Wisconsin’s are somewhat larger. In this entry, I add a third state, Indiana, to the statistical comparisons. As another medium-sized midwestern state, one might expect that Indiana would have criminal-justice numbers that are similar to Minnesota’s and Wisconsin’s. Indiana’s numbers, however, point to a criminal-justice sustem that is much larger and harsher than those of its northern neighbors.

As detailed in the table that appears after the jump, Indiana’s imprisonment rate (about 460 per 100,000) easily outstrips Wisconsin’s (387) and dwarfs Minnesota’s (178). Perhaps even more surprisingly, Indiana’s probation population also exceeds Minnesota’s. My Minnesota-Wisconsin comparison suggested that Wisconsin imprisons many defendants who would get probation in Minnesota, leading to a much smaller probation population in the former than the latter. But Indiana seems to incarcerate the same way that Wisconsin does, without any accompanying reduction in the probation numbers.

For that reason, Indiana’s total supervised population of 167,872 is the largest of the three states (although Minnesota, with the smallest overall population of three, still has a somewhat larger per capita supervised population, thanks to its enormous per capita probation number).

Indiana also leads the way in crime.
