The Prison Policy Initiative organized this website to be the starting point for anyone interested in learning more about the problem of prison gerrymandering.

The website's navigation menu is designed to give you an overview of prison gerrymandering: the problem and the solutions. Separately, the menu provides some starting places to take action in your community or at the national level.

The downside to producing so much information is that it can be difficult to find a particular piece of information that speaks to your specific need. This page provides an alternative introduction to the dozens of state-by-state and district-by-district reports, hundreds of articles and fact sheets, and thousands of communications with elected officials spread across both this topical website and our main organizational website.
