This data was obtained via Freedom of Information Act request by the Immigrant Legal Resource Center, and shared with the National Immigrant Justice Center (NIJC) for analysis. The set of 10 lists includes data on types of contracts, demographics, medical care providers, and inspections history for more than 1,000 federal facilities that detain immigrants, including county jails, Bureau of Prisons facilities, Office of Refugee Resettlement (ORR) centers, hospitals, and hotels (more on those down below). Customs and Border Patrol facilities are not included in the data. NIJC redacted location information (except for states) for ORR shelters to protect the safety of the children held in those centers. DHS compiled the data between November 4 and 6, 2017.
