The goal of the Safety and Justice Challenge is not only to reduce jail populations, but to do so safely—and this has been a pillar of the initiative since its inception in 2015. While previous briefs have highlighted the substantial reductions made in jail populations across SJC sites, this report provides an initial look at SJC’s decarceration strategies through a safety lens. More specifically, it explores how aggregate crime rates and returns to custody among people released from jail changed after the launch of SJC and the implementation of its decarceration strategies in sites through 2019. Overall, the findings suggest that decarceration strategies can indeed be crafted and implemented responsibly, without compromising public safety. In fact, public safety outcomes across SJC sites and in most individual sites remained relatively constant before and after the implementation of decarceration reforms.
