In 2020 and 2021, with support from the John D. and Catherine T. MacArthur Foundation’s Safety and Justice Challenge Research Consortium, the Urban Institute conducted in-depth process and impact evaluations of Durham County, North Carolina’s Misdemeanor Diversion Program (MDP). The findings of the impact evaluation are detailed in this report. Our evaluation found that from March 2014 to February 2020, law enforcement officers in Durham County referred fewer than one-quarter of all people eligible for diversion to the MDP, though when they did, the program had positive impacts.
