This from TRAC (published March 25 with ICE figures up through March 8):

The Trump administration continues to conceal most concrete details about its immigration enforcement activities – including where arrests are taking place, and who is being targeted and deported.…

Despite deploying staff from other agencies to assist in enforcement activities and ordering active-duty military to facilitate removals at the border, daily removals have failed to reach even the levels achieved by the previous administration. Indeed, President Trump’s removal record is growing worse with time rather than improving….

During the initial period at the end of January (January 26-31), ICE book-ins following arrests jumped to a daily average of 1,126. However, ICE was not able to sustain this level so that in the following period ICE book-ins following arrests fell to just 724 per day. This was 4.7 percent below Biden’s daily arrests of 759 during FY 2024….

Trump’s daily removals during the period of January 26-February 8 averaged just 693. This is 6.5 percent below the higher daily average of 742 under former President Biden. Now with an additional four weeks (28 days) added to the monitoring period, Trump’s daily removals for the period January 26 through March 8 averaged only 661 removals each day. This number is not only below its initial removal rate, but 10.9 percentage points lower than Biden’s daily average of 742.

However, the number of persons in detention, about 46,000, is higher than at any time during the Biden administration, per TRAC.
