The criminal justice system is big, it is complicated, and it is expensive. But how do we know what parts of it, if any, are working? Enter Mike Mueller-Smith.
A decade ago, Mike started building the Criminal Justice Administrative Records System (CJARS) a data infrastructure project that links criminal justice records across 40 states to employment outcomes, health data, and more. It is the kind of tool that makes you wonder why it didn’t exist sooner.
In this episode, we get into why criminal justice data is so fragmented, what it takes to stitch it together, and what researchers keep finding once they can actually see the full picture. We also talk about Mike’s Justice Outcome Explorer, which one of my favorite criminal justice data sites out there, a public dashboard built to help average Joes make sense of complex and sensitive criminal justice data.
Mike Mueller-Smith is the Co-Founder and Director of the Criminal Justice Administrative Records System (CJARS for short), a data infrastructure platform that is modernizing American research and statistical reporting capacity. He also is an Associate Professor of Economics at the University of Michigan and does research on the multi-faceted determinants of crime in the U.S. and the broad-ranging consequences of our criminal justice policy.
