I need your help. For 14 years, the Prison Policy Initiative has been at the forefront of the movement to keep the prison system from exerting undue influence on our electoral process. Our work has changed how our democracy works in 4 states and hundreds of local governments. We've even won at the Supreme Court, but our long-term viability depends on people like you investing in our work.

Can you stand up for democracy by joining our small network of donors today? You can make a one-time gift, or become a monthly donor. Gifts recieved in 2015 will be automatically matched by other donors.

I thank you for investing in our work for a more just tomorrow.

Group quarters data with prison locations now available in Google Earth

by Leah Sakala, December 14, 2011  

I was just working on a research project in which we needed to identify which state legislative districts had prisons in them. The state had released Google Earth files of its district maps, but getting the prison location data in the same format seemed like a tricky task without using expensive and complex GIS software. Luckily we’ve identified a simple solution: plugging the data from our Correctional Facilities Locator 2010 (a national database of correctional facilities counted by the 2010 census) directly into Google Earth.

By adding the relevant state’s Locator 2010 map file as a “Network Link” in Google Earth, I was able to quickly and efficiently pinpoint the locations of all correctional facilities in each state legislative district. Furthermore, each correctional facility entry includes the Census Bureau’s 2010 reported facility population and, when available, the name and type of the facility. Also, for every census block there is a link to detailed demographic information including race and age data for all incarcerated people counted in that block, providing the information necessary for in-depth analyses.

We’ve written up detailed instructions on how you can use this straightforward Google Earth method as well.
