How have the activities of U.S. Immigration and Customs Enforcement (ICE) changed in northern Utah since President Donald Trump took office?Significantly. In northern Utah, ICE is averaging more than 10 arrests per day since Trump’s second inauguration, more than 300 per month. That’s nearly three times ICE’s arrest count during the last two years of the Biden administration, when ICE averaged 2.5 arrests per day, or 76 per month.That’s one of the conclusions we can draw from the Deportation Data Project, which released new data on the subject late last month. The DDP, from the University of California, Berkeley, is a well-regarded research project that relies on federal Freedom of Information Act public records requests to track every immigration-related arrest, detention, and deportation that ICE undertakes. These records span from October 2022 through Aug. 5, 2026. The Salt Lake Tribune recently analyzed data in and around southern Utah and found that arrests had increased, even for those immigrants with no criminal records, and even as officials promised to target their operations to “the worst of the worst” offenders. Naturally, many readers wondered: Could the same approach be taken with the data from the Salt Lake Valley and the more populated northern half of the state?You asked, we listened. Here’s what we found.Arrests up in northern UtahGet Top Stories newsletter. The day’s biggest stories every morning, delivered right to your inbox.Rather than focusing on Salt Lake County or the populated Wasatch Front, we defined northern Utah broadly, including cities appearing in the DDP data from these counties: Box Elder, Cache, Carbon, Duchesne, Davis, Juab, Morgan, Rich, Salt Lake, Summit, Tooele, Uintah, Utah, Wasatch, and Weber. The goal here was to capture urban, suburban, and rural operations from the Salt Lake City ICE office.Just as we saw in southern Utah, ICE arrests have increased significantly during the Trump administration and have continued to rise in recent months. The most recent data dump from DDP saw a new high in northern Utah arrests in June, when there were 496 arrests, or more than 16 per day. Arrests have increased more than fourfold since Trump took office on Jan. 20, 2025, compared to the final 27 months of the Biden administration, the dates for which we have data. Overall, there have been more than 6,100 arrests in the area by ICE in the last 1.5 years.Arrests by cityWith the new arrest data, we can get a more accurate picture of which cities in particular ICE is impacting most. West Valley City has seen more ICE arrests than any other Utah city, with more than 1,100 over the past 20 months. Salt Lake City, Utah’s most populated city, ranks No. 2, while Spanish Fork in Utah County has seen 767 arrests, despite a population of just 50,000.(The city in which the arrest occurred is manually entered by ICE agents and is therefore prone to misspellings, but we tried to capture all that we could.)Who is being arrested?We also wanted to see if arrests had changed since White House border czar Tom Homan announced that ICE would prioritize targeted operations against national security and public safety threats on Jan. 29, 2026. Since that pledge, arrests have significantly increased, not decreased, from an average of 278 per month before the announcement to 405 per month after. The administration has also frequently highlighted ICE’s arrests and deportations of “the worst of the worst” — those who have been convicted of serious crimes.The most recent data released by ICE via the DDP does not contain information on whether immigrants arrested had faced charges for misdemeanors, felonies, or aggravated felonies, as previous releases had. However, the information on whether those who were arrested had been convicted of a crime, or merely had committed an immigration-based civil offense, remains in the data.Here’s that breakdown for northern Utah arrests:The data shows that immigrants arrested by ICE under Trump are less likely to have criminal convictions than those arrested by ICE under Biden, but are more likely to have charges pending against them. This field is recorded at the time of an immigrant’s arrest, so the increase in arresting those with pending charges is not just an artifact of Biden ICE arrestees having more time to work through the judicial system. Instead, it appears to indicate Trump’s ICE is quicker to arrest immigration violators while they have been charged, but before they have been convicted, of another crime.In recent months — since Homan’s targeted operations pledge — a slightly larger percentage of ICE arrestees have no criminal record at all, beyond the immigration offenses recorded by ICE. (Overstaying a visa is a civil offense, not a criminal one.) That percentage was 17.5% of arrestees before Homan’s pledge, and 26.3% after. We’ll continue tracking how ICE arrests change in the months and years to come. Keep an eye on Tribune reporting for more information.
