Institutional corrections refers to those persons housed in secure correctional facilities.
There are many different types of correctional facilities, operated by different government entities. Local jails are operated by county or municipal authorities, and typically hold offenders for short periods ranging from a single day to a year.
Private correctional facilities also operate under contracts for a wide variety of local, state, and federal agencies. Other correctional facilities are operated by special jurisdictions, including the U.S. Armed Forces, U.S. territories, and federal agencies, such as Immigrations and Customs Enforcement (ICE).
