Understanding the Detention System
Immigration detention operates as a decentralized, multi-jurisdictional network characterized by varying operational standards, opaque contracting mechanisms, and heavy reliance on private industry and local municipalities. As of February 2026, ICE holds 68,289 individuals in physical custody, with 73.6% having no criminal conviction.
This hub provides the tools and knowledge needed for rigorous oversight, litigation, and advocacy.
