EXPLAINER: Trump’s ICE Dragnet Has Hauled Parents Away From 146,635 American Children

Brookings estimates 146,635 U.S. citizen children have had a parent taken into ICE custody since Trump returned to office—and more than 22,000 have had every parent in their household hauled away.

STRIP AWAY the official euphemisms and the math is brutal. The Trump administration has booked roughly 400,000 people—almost all adults—into ICE detention after interior arrests since January 20, 2025, and in doing so it has put an estimated 146,635 American citizen children through the detention of at least one parent. That is the central finding of a report released Monday by the Brookings Institution, the venerable Washington think tank, authored by Maria Cancian of Georgetown, Nissi Cantu, Lanikque Howard of the University of Wisconsin–Madison, and Tara Watson, who runs Brookings’ Center for Economic Security and Opportunity. More than 22,000 of those children, the authors calculate, have lost every co-resident parent in their household to detention. About 36% are younger than six.

The administration would rather you not have a number. It prefers the passive voice and the soothing imprecision of “enforcement actions” and “removals,” language designed to give the impression that nothing has been done by anyone in particular. The Department of Homeland Security does publish its own count of detained parents of U.S. citizen children—18,277 in fiscal year 2025—and Brookings, with the restraint of professional academics, calls that figure “almost certainly a substantial undercount.” The reason is mundane and damning. The ICE Detained Parent Directive, issued in July 2025, still requires officers to ask people in custody whether they have children. In practice the question is often skipped, and when it is asked, parents with American kids at home have every incentive to keep quiet, since admitting to a child can mean inviting the state into that child’s life. A regime that does not want to know how many children it is separating from their parents will, with admirable efficiency, fail to find out.

Brookings did the work the government has declined to do. The researchers took the demographic profile of the roughly 400,000 adults booked into ICE detention from interior arrests between January 20, 2025 and April 9, 2026—country of origin, age, sex, marital status—and matched it against the population of likely undocumented adults in the Census Bureau’s American Community Survey, the largest rolling household poll in the country. The arithmetic falls out cleanly. About 27% of detainees turn out to be the live-in parent of a minor child. About 20% have an American citizen child at home. Run those rates across 400,000 arrests and you get roughly 205,000 children with a detained parent, of whom about 145,000 are U.S. citizens. Even a charitable extrapolation from DHS’s own anemic numbers produces about 60,000 affected citizen children. Whatever the precise figure, the floor is tens of thousands, and the floor is itself an indictment.

The composition of the affected families deserves a moment. Almost 54% of these American children have a detained parent from Mexico. Another 25% or so are tied to Guatemala and Honduras, two Central American countries long shaped by U.S. policy, regional instability, violence, poverty, and migration pressures Washington has never been able to bomb, bribe, outsource, or sermonize out of existence. Geographically, Washington, DC, and Texas top the list, with more than five children per 1,000 having a parent caught in the enforcement net. That is roughly one kid per elementary school classroom, give or take a sniffle.

What happens after the cuffs go on is, almost by design, a mystery. ICE, the Brookings authors note plainly, “does not directly involve itself in safeguarding the well-being of a detainee’s children” and refers a case to child protective services only when a child happens to be physically present at the arrest and no other adult is available to take them. The rest are absorbed by informal networks: a neighbor, an aunt, a church friend, the “family preparedness plan” that immigrant advocates now urge undocumented parents to draw up the way other parents draw up wills. A small share end up in foster care. Some American children are simply put on planes with deported parents and sent to countries they have never lived in. How many? The federal government does not publish that data. It has chosen not to ask.

The fate of the parents is somewhat better documented, thanks to outside journalism. A ProPublica investigation tracked ICE arrests of mothers of U.S. citizen children over the administration’s first seven months and found that 60% had already been removed from the country and another 17% were still in custody when the study closed. Detention, for the typical detained mother of an American child, functions as the runway to deportation rather than a brief administrative pause before a hearing.

The detention apparatus is being expanded, and aggressively so: the One Big Beautiful Bill Act, a piece of legislation whose name should embarrass a fourth-grader, dedicates $45 billion to building out detention facilities. About 60,000 people are held in ICE custody on any given day at the moment, with the ceiling poised to rise. Brookings counts roughly 13 million adults in the country who are undocumented or hold some kind of partial legal status, and they live with about 4.6 million U.S. citizen children. Around 2.5 million of those children could, in a worst-case scenario, see every parent in their household detained. The 145,000 separations on the books are a down payment on a much larger plan.

The standard defense—the law is the law, and the parents in question knew the risk—is the boilerplate of regimes that want to do cruel things without admitting they enjoy them. The law in question is being enforced selectively and theatrically, by masked agents in unmarked vehicles, with courthouse arrests, workplace raids, and explicit political targets. The children are American citizens. They chose nothing. They are, by the Fourteenth Amendment and every reasonable definition, ours.

The deepest scandal Brookings exposes is administrative. A serious government, faced with separating tens of thousands of its own citizen children from their parents, would at the very least keep a count. This one will not. DHS does not. ICE does not. Child welfare agencies, the report notes, often cannot or will not record that a case began with a federal arrest, sometimes because they fear flagging the family will make things worse, sometimes because their data systems were never built for the question. The vacuum is not innocent. You cannot be held to account for a harm you have refused to measure, and the refusal to measure is itself the policy.

Call this what it is: family separation at industrial scale, administered by a government that has mistaken a missing data field for a moral alibi. These children were orphaned by process, disappeared into the paperwork, and treated as clerical residue by the very country that owes them protection. The forms may hide them for now. History has a longer memory than ICE, and it keeps better records.

A Quick Ask: Because Independent Journalism Does Not Fund Itself.

Press freedom does not survive on vibes. It survives because readers decide the work is worth protecting. The Developer is independent, ad-free, and reader-funded—which means your support goes directly into the reporting, not into some billionaire’s pocket, corporate boardroom, or cowardly institution waiting for permission to fold. If my work helps you stay informed, consider upgrading to paid: $8/month or $80/year. If upgrading isn’t possible right now, sharing The Developer with someone who needs to read it matters just as much. Help keep independent journalism alive, loud, and impossible to buy.
