2010 Group Quarters Shapefile

To make the Census Bureau's Advance Group Quarters Summary File easier for redistricting professionals and advocates to use, the Prison Policy Initiative contracted with demographer and redistricting consultant Bill Cooper to produce a point shapefile with the group quarters counts for each block in the country.

The shapefile can be accessed here and a description of each field is below.

Please note that each block that contains a correctional facility contains a link to that block's entry in our database of annotations and that we accept additional annotations via that same link.

URL_FILE
Any block that contains a population counted in a correctional facility includes a URL to that block's entry in the Prison Policy Initiative's database of annotations of facilities.

We recommend accessing this database from the web or via HTML PopUps in ArcGIS rather than importing it directly into your local database.
