In fiscal year 2023, ICE detained about 272,000 people, and 33% were held in facilities run by private contractors. Planning documents tracked more than 6,000 beds in the nationwide detention capacity system, and public reporting followed 1,000+ detainee transports in a sample year. Across oversight snapshots and court reporting, detainee harm claims, legal access barriers, and health strain appear repeatedly across facilities.
