National Infrastructure

A modern country deserves a modern criminal justice system powered by comprehensive, accurate, and readily available data. To get there, we need to improve the way states collect, record, and release their data. Often this means developing and implementing data standards. This is how we do it:


MFJ does not lobby for specific policies, but we do work with policymakers, researchers, and others to improve statewide data policies. We do this by assessing a state’s legal and technological infrastructure for criminal justice data and providing guidance on best practices for collecting and standardizing criminal justice data, as well as on ensuring these data are accessible to researchers and the general public.

Creating a Standard National Set of Police Measures

Measures for Justice has been working for three years to develop a national set of police measures with input from community leaders and police departments. Now we are finally in a position to test, refine and pilot these measures in two communities, the West Sacramento Police Department in California and the Rochester Police Department in New York.

State of the Data

Coming soon is a comprehensive overview of what criminal justice data looks like state by state including what the existing criminal justice data laws are, which agencies collect criminal justice data, and whether states have taken any recent steps to improve their data infrastructure or access to the data. The microsite also includes a compendium of best practices and model legislation.

Data Standards

Another way to support criminal justice data infrastructure is to develop and implement data standards. Data standards, which include rules for recording and describing data, are important because they ensure consistency in both format and meaning, both of which are essential for sharing, integrating, and interpreting data within and across jurisdictions.

National Open Court Data Standards (NODS)

In 2019, MFJ worked with the National Center for State Courts (NCSC) to develop the National Open Court Data Standards (NODS). NODS include both business and technical court data standards to support the creation, sharing, and integration of court data by ensuring a clear understanding of what court data represent and how court data can be shared in a user-friendly format.

Justice Counts

Made possible by the support of the U.S. Department of Justice’s Bureau of Justice Assistance and led by The Council of State Governments Justice Center, MFJ is currently working on a 3-year effort to improve the availability and utility of criminal justice data. MFJ is leading the first phase of this effort, convening practitioners, researchers, and other stakeholders in law enforcement, courts, prosecution, indigent defense, jails, prisons, and community corrections to organize available data for each state and establish a set of key metrics that can drive budget and policy decisions.
