The Census Bureau’s monthly Current Population Survey indicates that the number of migrants declined by 1.6 million since Trump took office, with the total foreign-born population falling by 2.2 million. The bureau estimates that the illegal migrant population in the US now stands at 14.2 million.
The true illegal population remaining in the US is unknown. FAIR estimated in March 2025 that the figure could stand at 18.6 million. The Center for Immigration Studies (CIS) put the figure at 15.8 million, representing a 50% increase since 2021. The total foreign-born population reached 53.3 million in January 2025, according to most estimates, with illegal migrants composing around 29% of that figure.
Under Biden, new arrivals were averaging 120,000 per month, but over the last six months, America has seen the illegal population declining by 270,000 on a monthly basis. “The best evidence we have is that the illegal population is now falling at a rate that even exceeds the massive growth that we had in Biden’s four years,” CIS research director Steven A. Camarota said. Camarota indicated that if the current trend persists, the nation could see the total foreign-born population decline for the first time in nearly 100 years.
“It’s likely that this represents a savings in money for the taxpayer,” he said. “It will take pressure off schools and hospitals and other services. It’s likely it will potentially create job opportunities for Americans.”
Less than a year ago, cities were scrambling for housing solutions for migrants. State and city budgets had toppled, and the number of arrivals steadily soared to the point where it was absolutely fiscally impossible for any local, state, or even the federal government to adequately maintain the illegal population.
The open border policy was absolutely treasonous. This authorized invasion cannot be solved overnight. Some estimates believe it could take over a decade to deport everyone who entered under Biden-Kamala-Schwab, with some estimates believing it will take 30 years. Again, no one knows exactly who or how many people entered the borders, and this effort could halt under a new administration.
