Immigration and Customs Enforcement (ICE) detention numbers have seen a dramatic uptick since early 2023, with figures more than doubling during the transition from President Biden’s administration to President Trump’s second term. Recent data from TRAC Reports, which monitors U.S. immigration enforcement statistics, reveals detention populations have surged from approximately 20,500 individuals in January 2023 to over 56,000 by mid-June 2025.
The most significant increase has occurred among non-criminal immigration violators, who represent the largest segment of detainees. This category has expanded from roughly 11,200 individuals at the start of 2023 to more than 26,000 by mid-2025. While detentions of individuals with criminal charges or convictions have also increased, the substantial growth in non-criminal detentions reflects a marked shift in enforcement priorities under the Trump administration.
During Biden’s presidency, total detention figures maintained relatively stable levels, fluctuating between 20,000 and 40,000 individuals. However, since Trump’s return to office, particularly from January 2025 onward, ICE has rapidly expanded its detention operations. The last two weeks of available data alone showed an increase of more than 5,000 detainees.
This current trend mirrors patterns seen during Trump’s first term, when detention levels consistently exceeded 50,000, reaching peak numbers in mid-2019. The present trajectory suggests these historical highs may be matched or surpassed in the coming months.
Breaking down the latest figures from June 15, 2025, the detention population comprises approximately 15,964 individuals with criminal convictions, 14,263 with pending criminal charges, and 26,170 classified as other immigration violators. This represents a 175% increase in total detentions compared to January 2023 levels.
The rapid expansion aligns with Trump’s campaign promises to intensify immigration enforcement efforts. The administration’s approach has particularly focused on individuals without criminal records, as evidenced by the substantial growth in the “Other Immigration Violator” category.
The data demonstrates a clear contrast between the two
administrations’ enforcement strategies. While the Biden
administration maintained more moderate detention levels with less emphasis on non-criminal violations, the Trump administration has pursued a more aggressive approach to immigration enforcement across all categories.
The weekly totals tracked by TRAC Reports show a consistent upward trend since Trump’s return to office, with the steepest increases occurring in recent months. This pattern indicates a significant policy shift in how immigration enforcement is being prioritized and implemented at the federal level.
The current surge in detentions represents one of the most substantial increases in ICE custody numbers in recent years. The rapid growth, particularly in non-criminal detentions, signals a return to the more stringent immigration enforcement policies characteristic of Trump’s first term.
This shift in enforcement priorities is reflected not only in the overall numbers but also in the changing composition of the detained population, with non-criminal immigration violators now comprising a larger proportion of those in ICE custody than at any point during the Biden administration. The data suggests this trend may continue as the administration pursues its stated immigration policy objectives.
