The Cook County Department of Corrections (CCDOC) is the largest single-site jail in the United States, holding approximately 9,000 inmates on any given day. The CCDOC is responsible for providing safe and secure detention for individuals charged with or convicted of crimes in Cook County, Illinois.
The CCDOC has been the subject of much controversy in recent years, with critics alleging that the jail is overcrowded, understaffed, and provides inadequate medical and mental health care to inmates. In 2017, a federal judge ordered the CCDOC to reduce its population by 1,000 inmates due to concerns about overcrowding. The CCDOC has since taken steps to reduce its population, including releasing inmates early and expanding its use of electronic monitoring.
