The United States incarcerates more individuals per capita than any other country in the world. Without the ability to compare performance and identify trends at all levels of the system, injustices may become more prevalent and become accepted as the status quo.  Formed 2011, Measures for Justice (MFJ) is committed to bringing transparency to the criminal justice system by collecting, cleaning, and coding criminal justice data at the county level to publish on a free data portal and use data patterns to facilitate discussions about the justice system. MFJ’s founding goal was to create a series of measures to gauge the performance of the criminal justice system at the county-level. Its approach was designed to be collaborative, encouraging justice practitioners at the county-level to provide feedback on MFJ’s measures, data, and contextual information throughout the process to advance three criminal justice system goals: fair process, public safety, and fiscal responsibility. The Bureau of Justice Assistance (BJA) recruited MFJ to refine its justice system series of measures and undertake a pilot program to gather the corresponding data elements to support those measures as part of a BJA National Training and Technical Assistance Center (NTTAC) engagement.
