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.

Graph showing the state prison incarceration rate for the United States from 1925 to 2012 and the incarceration rates for 5 select states from 1978-2012. The graph shows that the diversity between the states is almost as dramatic -- and sometimes contrary to -- the larger national trend.

Data Source: For detailed sourcing, see http://www.prisonpolicy.org/reports/overtime.html#select50. (Graph: Peter Wagner, 2014)

This graph originally appeared in Tracking State Prison Growth in 50 States.
