Over 145,000 US children separated from parents since Trump’s ICE surge, study estimates
About 36% of children whose parents were detained were younger than six, Brookings Institution study found
More than 145,000 US children have likely experienced a parent being detained by immigration authorities since the start of Donald Trump’s second presidency, according to a new report published by a reputed US thinkthank.
The report, released Monday by the Brookings Institution, estimates that about 146,635 children who are US citizens have had a parent detained during the mass deportation campaign the Trump administration embarked on after he retook office in early January. The study further found that of those children, more than 22,000 experienced the detention of all of their co-resident parents.
Roughly 36% were younger than six years old, underscoring a hardline immigration enforcement strategy that has drawn widespread criticism from civil rights and immigrant advocacy groups.
The Brookings Institution’s report also found that the largest share of US citizen children with a detained parent are linked to Mexico, accounting for nearly 54%, while children with parents from Guatemala and Honduras together make up more than 25%.
Washington DC and Texas have had the highest share of American children with an affected parent, with more than five per 1,000 facing parental immigration detention, according to the report.
Brookings researchers noted that the US Department of Homeland Security (DHS) reported 18,277 detainees with US citizen children in fiscal year 2025 – but said the figure is “almost certainly a substantial undercount”.
Earlier in May, a Guardian investigation had found that the arrest of about 18,400 parents had affected as many as 32,000 children in the first seven months of 2025 alone. That figure included at least 12,000 US citizen children.
The investigation also found that the Trump administration had arrested about 2,300 parents and deported about 1,400 parents each month in 2025 – nearly double the monthly deportation rate recorded in 2024 during the end of Joe Biden’s presidency.
Brookings researchers pointed to anecdotal evidence suggesting that many immigrants are either not asked whether they have children or choose not to disclose that information out of fear. Instead, they relied on demographic data from the Detention Data Project, matching detainees’ characteristics – including country or region of origin and marital status – with similar undocumented individuals identified in the American Community Survey (ACS), a nationally representative household survey.
Roughly 13 million adults in the United States are undocumented or hold only limited legal protections. As a result, more than 4.6 million US citizen children live with at least one parent vulnerable to deportation – and about 2.5 million could face the detention of all parents in their household.
“For both logistical and political reasons, the administration will not achieve its stated goal of removing every unauthorized immigrant from the United States,” researchers said. “At a minimum, DHS should collect and publicly report accurate data on the number of parents facing detention or deportation, as well as the number of US citizen children who leave the country following a parent’s removal.”
Researched as added: “As immigration enforcement expands, ensuring that affected children have access to basic supports and protections should be understood not as optional, but as a necessary governmental responsibility tied to the foreseeable consequences of family separation and displacement.”
In a statement to the Guardian, a DHS spokesperson argued that “being in detention is a choice”.
“ICE does not separate families,” the spokesperson said. “Parents are asked if they want to be removed with their children or ICE will place the children with a safe person the parent designates. This is consistent with past administration’s immigration enforcement.”
The spokesperson added, among other things, that “parents can take control of their departure” from the US with the CBP Home app “and reserve the chance to come back the right legal way”.
In March, a report by the Women’s Refugee Commission (WRC) and Physicians for Human Rights (PHR) found that the Trump administration deported many immigrant parents without asking whether they had children or allowing them to decide if their children would accompany them.
2.5 million is hard to ignore, no matter which side you are on.
Reading that roughly 36% were younger than six years old, underscoring a hardline immigration enforcement strategy that has drawn widespread criticism from civil rights and immigrant advocacy groups — hard to argue with the logic there.
Earlier in May, a Guardian investigation had found that the arrest of about 18,400 parents had affected as many as 32,000 children in the first seven months of 2025 alone. Meanwhile brookings researchers pointed to anecdotal evidence suggesting that many immigrants are either not asked whether they have children or choose not to disclose that information out of fear.
Think about it: washington DC and Texas have had the highest share of American children with an affected parent, with more than five per 1,000 facing parental immigration detention, according to the report. That speaks volumes.
The detail about about 36% of children whose parents were detained were younger than six, Brookings Institution study is something people should sit with.
Considering earlier in May, a Guardian investigation had found that the arrest of about 18,400 parents had affected as many as 32,000 children in the first seven months of 2025 alone, it raises some real questions about what happens next.
Joe Biden has been vocal about this, good to see them staying on it.

Joe Biden has been pushing this agenda for a while now.

In other words brookings researchers pointed to anecdotal evidence suggesting that many immigrants are either not asked whether they have children or choose not to disclose that information out of fear. Curious to see how this develops.
When you look at washington DC and Texas have had the highest share of American children with an affected parent, with more than five per 1,000 facing parental immigration detention, according to the report, the implications are hard to ignore.
13 million is hard to ignore, no matter which side you are on.
