About this Topic

BJS collects data on both noncitizens held in state or federal prison or local jail, and on persons held by the U.S. Immigration and Customs Enforcement (ICE). Note - there is an important difference between the terms noncitizens and inmates held by or for ICE. See Terms and Definitions for more information. 

U.S. Immigration and Customs Enforcement detainees - BJS obtains yearend prison counts of persons detained by U.S. Immigration and Customs Enforcement (ICE), formerly the U.S. Immigration and Naturalization Service, an agency within the Department of Homeland Security. The Annual Survey of Jails also collects jail counts persons held for ICE. ICE inmates may be held for immigration violations in federal, state, and locally operated prisons and jails, privately-operated facilities under exclusive contract, and ICE-operated facilities.
