While ICE’s latest statistics for each detention facility appear to have corrected erroneous numbers posted two weeks ago, the list of detention facilities still appears incomplete. One obvious omission is that ICE is still not including the new Florida facility in the Everglades.

ICE does not release a snapshot count of the number of individuals currently detained in each facility. Nor does the agency release the facility’s contractual capacity. As TRAC discussed in a previous report, this lack of reporting makes it impossible to see how incomplete the list of facilities actually is or how many beds are currently available to ICE. If the public had the number currently detained at each facility, summing up these numbers should add exactly to ICE’s national total for the number currently detained. And summing up the contractual capacity for each will inform the public just how many beds ICE still has available but are currently unused.

While ICE has actively sought to expand the number of detention facilities including applying pressure to more state governors to agree to furnish beds. The latest release listed 179 detention facilities, while 201 were listed at the end of June. ICE adjusts its list based on whether the facility had “a population count of greater than or equal to 1 as the time of the data pull.”

The number monitored by the so-called “Alternatives-to-Detention” program has dropped slightly from 185,824 at the end of May to 182,799 actively enrolled in the program as of July 26, a trend continuing their consistent decline since President Trump took office. However, ICE officials have recently communicated that they intend to prioritize ankle monitors for use in the program. While overall numbers continued dropping, including significant declines in the usage of SmartLINK and wrist-worn technologies, the number of people assigned to wear ankle monitors rose to 25,670 at the end of July, compared to 21,569 at the end of May. According to the most recent update, ankle monitors were most often used by ICE’s Chicago office, with 3,259 people tracked using ankle-worn devices. The Washington, D.C. office showed the sharpest jump with 795 monitored via ankle monitors at the end of May compared to 2,339 now assigned to wear ankle monitors as of July 26, 2025.

*Note: TRAC Reports has adjusted its definition of criminal history. Previously, anyone recorded by ICE as having “Pending Criminal Charges” was identified as having a criminal history. From this update and going forward, detainees with pending charges will not be considered as having a criminal record.
