Peter Wagner, Executive Director
I need your help. For more than a decade, the Prison Policy Initiative has been at the forefront of the movement to expose how mass incarceration undermines our national welfare. We've won major civil rights victories in local governments, state legislatures and even the Supreme Court. But our long-term viability depends on people like you investing in our work.

Can you stand up for smart and effective justice policy by joining our small network of donors today? You can make a one-time gift, or even become one of our sustaining monthly donors.

I thank you for investing in our work towards a more just tomorrow.

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.
