Executive summary
As of January 2025, the U.S. foreign‑born (immigrant) population was reported at 53.3 million, a record high, though government and independent tabulations show the number fell through mid‑2025 to about 51.9 million as surveys and analysts tracked departures and removals [1] [2]. Estimates of the unauthorized subset vary widely — from roughly 14–15 million in some academic tabulations to advocacy and advocacy‑aligned groups claiming higher totals — reflecting deep methodological disagreements across sources [2] [3].
1. What the headline numbers say: a peak, then a decline
Government survey tabulations and major research centers reported that the immigrant population reached 53.3 million in January 2025, equal to roughly 15.8–16 percent of the U.S. population, before falling by more than a million to about 51.9 million by June or mid‑2025 according to Pew and related summaries [1] [2]. Some analyses of the same Current Population Survey (CPS) raw data showed even larger declines between January and July 2025 — a 2.2 million drop reported by the Center for Immigration Studies (CIS) based on CPS figures — though that magnitude has been disputed by other experts [4].
2. Why the totals diverge: surveys, methods and political context
Differences in counts stem from how surveys are weighted, which data streams are used, and whether analysts adjust for people who avoid government surveys; the January 2025 CPS was reweighted to reflect recent migration, producing the 53.3 million peak, and later months show lower counts that may reflect real departures or methodological artifacts [5] [4]. Economists and demographers caution that the steep CPS decline likely overstates the true outflow because respondents may be less willing to engage with government surveys amid heightened enforcement and data‑sharing concerns, a point raised by PIIE and other skeptics [6].
3. The unauthorized population: contested estimates
Estimates of people in the U.S. without lawful status vary widely: some academic and government‑linked tabulations put the unauthorized population at roughly 14–15 million in recent analyses, while advocacy and restrictionist groups publish higher figures — for example FAIR estimated about 18.6 million in early‑to‑mid 2025 — reflecting divergent methods, assumptions about arrivals, and inclusion of recent parolees or guestworkers [2] [3]. These disputes matter because headline immigrant totals (53.3M, 51.9M) include everyone foreign‑born, regardless of legal status, whereas policy debates often hinge on estimates of the unauthorized subset [1] [3].
4. What official projections and fiscal analyses add
The Congressional Budget Office and Federal Reserve Bank analysts have incorporated new enforcement policies and flows into projections that reduce net migration expectations for 2025 and beyond; CBO notes administrative actions and legislation that lower projected immigrant counts and has adjusted population growth projections accordingly [7]. The San Francisco Fed estimated net migration in 2025 would be far lower than 2024, nearer to roughly half a million, which would blunt labor‑force growth compared with previous projections [8].
5. How to read the numbers: a cautious conclusion
The best, directly reported baseline is that roughly 53.3 million foreign‑born people lived in the United States in January 2025, with most mainstream analyses agreeing the mid‑2025 total had fallen to about 51.9 million — but the scale and cause of that decline remain debated, with some analysts arguing survey nonresponse and enforcement fears exaggerate outflow figures while others point to real rises in departures and removals [1] [2] [6]. Claims about the exact size of the unauthorized population are even more contested, so any single figure should be treated as an estimate contingent on the method used [3].
