Philadelphia formed its Criminal Justice Advisory Board (CJAB) in 2008 as a collaborative council composed of local criminal justice and social services stakeholders. By conducting periodic system assessments and developing performance indicators to determine progress in meeting collective goals, CJAB members use their program and policy expertise to take a systematic approach to addressing a broad range of criminal justice issues.
Among the CJAB’s successes, recent collaborative efforts among criminal justice, health and community partners have led to better use of data and the implementation of innovative practices to reduce Philadelphia’s jail population. In just a few short years, Philadelphia successfully reduced its jail population by roughly 41 percent (from 8,082 in July 2015 to approximately 4,700 as of February 2020).
Collaboration and coordinated efforts among CJAB members have not only helped drive down Philadelphia’s jail population, but also helped shift the culture within local agencies around data collection and usage. This case study highlights some of the initiatives and practices that Philadelphia has implemented to better coordinate, evaluate and share its criminal justice data to serve vulnerable residents.
Data-Driven Justice (DDJ) is a project of the National Association of Counties (NACo) and Arnold Ventures that aims to support local jurisdictions in using data to better align resources to respond to people experiencing a behavioral health crisis, particularly those who are frequent utilizers of justice, health and human services systems.
