Measures for Justice

Amy Bach


Measures for Justice (MFJ) was founded in 2011 to develop a data-driven set of performance measures to assess and compare the criminal justice process from arrest to post-conviction on a county-by-county basis. The data set comprises measures that address three broad categories: Fiscal Responsibility, Fair Process, and Public Safety.

MFJ’s mission is o use data to measure and understand county-level criminal justice system performance.

Measures for Justice aims to fix systemic problems in the criminal justice system by shining a light on criminal justice ‘performance’ through county-level comparative data. In 2014 PSF made a $3 million bet on a $1 million organization founded by Amy Bach, an Echoing Green Fellow. MFJ has cleaned and coded data from 300 counties across six states, and launched a data portal in the spring of 2017. MFJ has grown from two employees to 30, and has used PSF’s initial funding to leverage an additional $13 million in support, most recently from the Laura and John Arnold Foundation,, MacArthur Foundation, and the Chan Zuckerberg Initiative.
