The Prison Policy Initiative works hard to organize all of the research about the criminal justice system so that you can find it and use it in your work. Can you help us grow this essential service?

Thank you for supporting an educated and informed movement.

Research Clearinghouse:

Beyond producing original research, the Prison Policy Initiative edits several databases to empower activists, journalists, and policymakers to shape effective criminal justice policy. This page contains links to virtually all the empirical criminal justice research available online, organized by category and publication date. If you know what you are looking for, you may also search the database. We also have an email newsletter (at right) for new research clearinghouse updates.
