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.

National data


State-level criminal justice data (all states)


Data specific to only one state:


Population data (for calculating incarceration rates, etc.)
