According to their most recent update, Immigration and Customs Enforcement (ICE) currently detain 46,269 people as of March 9, 2025, the highest number of detainees since October 2019, when ICE detained 49,419 individuals. But this is still below detention levels during the first Trump administration before the COVID-19 pandemic. Since the last detention report two weeks ago when detention levels were reported as 43,759, ICE has been increasing the number of detainees by around 400 each day.
ICE has also begun releasing detention numbers for two facilities located at Guantanamo Bay. According to the statistics, a facility entitled JTF Camp Six has an average daily population of 9 individuals while another center called Migrant Ops Center Main holds an average of 4 detainees per day. This seemingly contradicts reporting from the press indicating that dozens of people have been flown to and then detained at Guantanamo two different times over the past few months.
A bit of math makes some sense out of what can appear to be a discrepancy upon first reading. Average daily population is calculated based on the average population during all days in the fiscal year to that point (e.g. January 20 was the 112th day of fiscal year 2025). If detainees are only held at a location for a limited number of days before the facility is emptied out, as is consistent with media reporting, the average daily population may be much lower than the real number of individuals detained at that center on any given day.
