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. With a lot of hard work and generous support from a small network of individual donors, 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.

Through the end of 2014, your contribution to our work will stretch twice as far thanks to a match commitment from a small group of other donors like you.

I thank you for your investment in our work towards a more just tomorrow.
—Peter

Census Bureau releases group quarters data

by Peter Wagner, April 22, 2011  

The Census Bureau released the Advance Group Quarters yesterday — earlier than expected — and many have been eagerly awaiting this data so that they can identify prison populations in the redistricting data and avoid prison-based gerrymandering.

The Prison Policy Initiative, in partnership with Demos, issued a press release about the Advance Group Quarters File yesterday. A copy of the press release can be found below.

Late last night, the Prison Policy Initiative finished translating the Bureau’s data in to some user-friendlier formats, including:

  • A national shapefile with all of the group quarters data
  • Block level tables of the correctional facilities searchable by county
  • Google maps of the blocks that contain facilities
  • Connecting the new census data to a database of annotations of each of the 5,393 blocks that contain some kind of correctional facility.

These tools are available at http://www.prisonersofthecensus.org/data/. Our next conference call workshop to discuss how to use this data to avoid prison-based gerrymandering will be at 10am eastern on Tuesday April 26.

    Where can I find information about how many correctional facilities are present in each state? Is there a place on the internet where lists of correctional facilities by state is published (other than wikipedia)? Please e-mail me if you have any information on this.
