I need your help. I co-founded the Prison Policy Initiative to put the problem of mass incarceration — and the perverse incentives that fuel it — on the national agenda. Over the last 17 years, our campaigns have protected our democracy from the prison system and protected the poorest families in this country from the predatory prison telephone industry. Our reports untangle the statistics and recruit new allies.

But now, more than ever, we need your help to put data & compassion into the conversation.

Thank you.

The United States locks up more people, per capita, than any other nation. But grappling with why requires us to first consider the many types of correctional facilities and the reasons that 2.3 million people are confined there.
