San Francisco referred over 16,000 individuals between 2008 and 2018 through the Collaborative Courts and Pretrial Diversion programs; overall one quarter of filed criminal cases were referred to diversion. People who were referred to diversion programs had longer criminal justice histories than those whose cases were not referred, but were otherwise demographically similar. Referred cases had lower conviction rates than nondiverted cases, but referred individuals had higher rates of subsequent criminal justice contact, on average. Individuals who were re-arrested after a diversion referral were typically arrested on less severe offenses than the original offenses. While this paper does not present causal estimates of the effects of diversion programs, future research will estimate the impacts of a referral to diversion on case outcomes and subsequent criminal justice contact, among other outcomes.
