DHS reported a total of 58,766 "known or suspected" aliens in the custody of federal authorities. According to the Federal Bureau of Prisons, there are 184,379 total federal inmates, meaning that almost 32 percent of all federal inmates are aliens. The number of aliens in federal custody has risen since the last report: At that time, the Justice Department estimated that there were 42,000 aliens, representing 24 percent of the federal prison population.
Of the 58,766 "known or suspected" aliens, ICE could confirm that 37,557 (64 percent) are confirmed aliens, defined as meaning that they are non-citizens and foreign-born. From that group of 37,557 ICE-confirmed aliens, an astonishing 35,334 (94 percent) were illegally residing in the United States.
