The number of children in Immigration and Customs Enforcement detention on a given day has skyrocketed, jumping more than sixfold since the start of the second Trump administration. The Marshall Project analyzed data obtained by the Deportation Data Project and found that ICE held around 170 children on an average day under Trump, showing the sixfold increase in children in ICE detention facilities. During the last 16 months of the Biden administration, ICE held around 25 children a day.

The Marshall Project’s analysis found that on some days, ICE held 400 children or more. The data covers September 2023 to mid-October 2025, meaning it does not include the surge of arrests from recent immigration enforcement operations in Minnesota. Nor does the data include children in the custody of the Border Patrol or the Office of Refugee Resettlement, where children are held without a guardian.

The Dilley Immigration Processing Center in Texas is the main facility for family detention. U.S. Rep. Joaquin Castro spent two-and-a-half hours inside Dilley on Wednesday, visiting parents and children. He said that the 1,100 detainees housed at the facility included a 2-month-old infant. “They are literally being treated as prisoners,” said Castro, a Democrat from San Antonio, in a live-streamed video. “This is a monstrous machine.”

In 2021, Biden largely halted the practice of family detention, and the Dilley facility, which had mostly housed families, closed in 2024. But the Trump administration revived the practice last year, and the facility, which is located about 75 miles outside of San Antonio, reopened.

The detainment of children by ICE has led to protests in recent weeks, both inside and outside Dilley. On Wednesday, state police used pepper spray on people protesting outside.

Immigration attorney Eric Lee was visiting clients at the facility on Saturday when staff abruptly told him to leave. Outside, he could hear a large group of children and women detained inside chanting, “Let us out.” Lee said he later learned that families inside the detention center had gotten news that people across the country were protesting the detainment of 5-year-old Liam Conejo Ramos, whose story went viral amid the backlash against the Trump administration’s recent immigration enforcement surge in Minnesota.
