According to the latest data from Immigration and Customs Enforcement (ICE), twelve immigrant
detention facilities in the United States currently have an average daily population of over 1,000
detainees each. These facilities are mainly located in the U.S. South and Southwest, including five
facilities in Texas, two in Louisiana, and one each in Arizona, California, Georgia, and Mississippi,
as well as one in Pennsylvania.
The top five facilities with the highest average daily population (ADP) include the South Texas Family
Residential Center in Dilley, Texas, at 1,868 followed by the South Texas ICE Processing Center
located in nearby Pearsall at 1,659. Private contractors run these two facilities, as well as Stewart
Detention Center in Georgia, which has the fourth highest ADP currently of 1,514. The facility with
the third highest ADP (1,594) is Adams County Detention Center in Mississippi while Winn Correctional
Center in Louisiana has the fifth highest ADP (1,483). These two facilities are publicly owned but
have a contract with ICE to provide beds for civil immigrant detention.
The remaining facilities with an ADP of at least 1,000 include Eloy Federal Contract Facility in
Arizona (1,400), Otay Mesa Detention Center in California (1,211), Karnes County Immigration
Processing Center in Texas (1,206), Moshannon Valley Processing Center in Pennsylvania (1,189),
Montgomery ICE Processing Center in Texas (1,181), Port Isabel SPC in Texas (1,103), and Jackson
Parish Correctional Center in Louisiana (1,055). An entire list of the ADP of ICE’s facilities updated
through the end of December can be found on TRAC’s website
A note on the data. Although ICE’s published detention data provides national totals of its detained
population on a given day, ICE’s data on individual detention facilities reports “average daily
population” (ADP) for a fiscal year. ADP does not represent the total number of migrants currently
detained in the facility, but rather an average of the daily population since the start of the fiscal
year. As a result, changes in a facility’s ADP numbers tend to moderate any month-to-month changes
particularly as statistics reflect averages across more months as the fiscal year goes by. This then
can produce a marked change when figures at the end of a fiscal year are compared with those for the
first month of a new fiscal year. For instance, the overall growth in ICE’s detained population toward
the end of FY 2023 and early months of FY 2024 meant that the ADP for the South Texas Family
Residential Facility leapt from 1,099 on September 30, 2023, to 2,046 on October 10. Since October is
the first month of a new fiscal year, the ADP on October 10 more closely represents the real detained
population whereas fluctuations late in the fiscal year in September are smoothed out by a full year’s
worth of data. Readers should be cautious not to confuse ADP with currently detained totals.
The total number of detained immigrants currently stands at 37,131. TRAC recently reported on the
growing total number of detainees
as well as
growing lengths of detention
stays of detained migrants.
