About
World Prisons exists because basic facts about prisons — how big they are, who runs them, how to write to someone inside — are scattered across hundreds of websites and harder to find than they should be. We pull them into one place.
Who it's for
- Families looking up visiting times or mailing addresses.
- Researchers comparing systems internationally.
- Journalists checking population and overcrowding figures.
- Advocates documenting conditions across multiple jurisdictions.
What's next
- Expand from 10 to 100+ countries.
- Add facility-by-facility data for the 20+ largest systems.
- AI-powered semantic search across conditions reports.
- Comparison tools for systems and individual facilities.
- A submission system for verified corrections from staff, families, and advocates.
