Measures for Justice in

California has long been at the forefront of criminal justice change and innovation. Over the last decade, California has passed a series of laws designed to reduce the number of people under correctional supervision by reclassifying a range of offenses to be eligible for less serious criminal penalties. At the same time, California has moved to increase transparency in its criminal justice system, launching the OpenJustice web portal in 2015 and passing the Open Justice Data Act in 2016.

It is in this spirit that Measures for Justice began working in the state, in November of 2017, collecting criminal justice data from all 58 counties. The goal is to be able to return to California cleaned data sets that can speak to how well reforms have been working and that can gauge, in general, where success stories are being written for replication elsewhere.

To address the challenges our criminal justice system is facing and identify knowledge and evidence-based best practices, we need data from all criminal justice stakeholders, at the county levels. I firmly believe in the mission, goal, and method of Measures for Justice and I welcome the transparency it brings to our criminal justice system!

County with county or city agency sharing data

California's criminal justice system is decentralized across the state's 58 counties. There is no one central repository for county-level data or single body that provides oversight of all criminal justice data collection. In addition, while California statutes explicitly allow Criminal Offender Record Information (CORI) to be shared with "bona fide research organizations," California Rules of Court are more ambiguous regarding the sharing of criminal court records. Taken together, data collection in this state is a challenge.

As we collect data from agencies across the state, we will begin the process of cleaning and coding the data to prepare it for our data portal.
