DOJ Releases New Numbers: One-in-Five Federal Prisoners Are Foreign Born, Most Illegal Aliens

{snip}

A total of 58,766 known or suspected aliens were in in DOJ custody at the end of FY 2017, including 39,455 persons in BOP custody and 19,311 in USMS custody.

Of this total, 37,557 people had been confirmed by U.S. Immigration and Customs Enforcement (ICE) to be aliens (i.e., non-citizens and non-nationals), while 21,209 foreign-born people were still under investigation by ICE to determine alienage.

Among the 37,557 confirmed aliens, 35,334 people (94 percent) were unlawfully present. These numbers include a 92 percent unlawful rate among 24,476 confirmed aliens in BOP custody and a 97 percent unlawful rate among 13,081 confirmed aliens in USMS custody.

This report does not include data on the foreign-born or alien populations in state prisons and local jails because state and local facilities do not routinely provide DHS or DOJ with comprehensive information about their inmates and detainees. This limitation is noteworthy because state and local facilities account for approximately 90 percent of the total U.S. incarcerated population. DHS and DOJ are working to develop a reliable methodology for estimating the status of state and local incarcerated populations in future reports.

Illegal alien incarceration costs American taxpayers nearly $2 billion each year.
