Allegheny County is committed to allocating criminal justice resources in a systematic way, utilizing evaluation and evidence-based programming to better understand the costs and benefits of various programs. To further this goal, Allegheny County partnered with the Vera Institute of Justice to implement a system of cost–benefit analysis throughout its criminal justice system. The cost analysis includes the cost of an arrest, the cost per day of incarceration or detention, and the cost per day of supervision, including adult and juvenile caseloads, in Allegheny County.
What can we learn from calculating costs in the criminal justice system?
Understanding the drivers of costs within these systems (e.g., changes in population served, changes in operating costs, or both) allows analysts to value the benefits of current and proposed programs. This information is also valuable for policy-makers who can compare the benefits and costs of programs to make informed management, budget and program decisions.
