How many immigrants has ICE arrested and detained so far this year? Here's what we know.
By Lauren FitzPatrick


The Transactional Records Access Clearinghouse also maintains a database of immigration violations and detentions among its collection of giant government datasets. Many of TRAC’s data tools can be customized on its website. This collective of researchers at Syracuse University behind TRAC has long relied on the Freedom of Information Act to produce its rich data. But that also means a lag in when data is provided, so any ICE enforcement in Chicago this week won’t immediately show up in TRAC’s datasets or in those made public by the Deportation Data Project. TRAC sums up its purpose: “to provide the American people — and institutions of oversight such as Congress, news organizations, public interest groups, businesses, scholars, and lawyers — with comprehensive information about staffing, spending, and enforcement activities of the federal government. On a day-to-day basis, what are the agencies and prosecutors actually doing?” Nationally, the number of ICE detentions is up 69% this year over 2024 as 25,003 more people were detained from mid-January until the end of August. Of those detained in 2024, 37% were arrested by ICE and 63% by Customs and Border Protection. This year, 76% have been arrested by ICE and 24% by Customs and Border Protection.
