Case Study

Measures for Justice: National Data Portal

The Measures for Justice data portal, launched in 2017, and offered unprecedented transparency into local justice systems by collecting and analyzing criminal justice data and presenting them at the county level. The portal allows users to review and compare performance data of their local criminal justice system broken down by defendant and case characteristics such as race, sex, and offense severity.

As the Measures for Justice Director of Technology, I built a team of engineers and designers from 2015 to 2020 to conceptualize and deliver the National Data Portal. This project was a huge undertaking by a small team of engineers and researchers who believed in an idea that everyone else said was impossible. Our hard work resulted in coverage in The New York Times, The Marshall Project, Salon and many others and established Measures for Justice as the leader in the criminal justice transparency space.

“It’s a sad reality that in today’s America there is no easy way to access the most basic criminal justice data from across the country. Better access to criminal justice data is important for informing efforts to make our communities safer and our criminal justice system fairer—after all, you can’t solve a problem if you don’t have the facts. We’re thrilled to be supporting Measures for Justice’s work.”

For each state measured users are able to select their county and see how their local criminal justice system is performing across our performance measures.

The national data portal had a significant impact on the criminal justice reform movement by providing transparency into local justice systems. The following video shows how people are using our data.

Since 2020, I worked to help Measures for Justice shift to a new model of partnering more closely with county practitioners and their communities to allow greater transparency and impact through Measures for Justice Commons.
