U.S. Foreign-Born Population Hits Record 15.8% Following Surge Under Biden Administration

New data reveals the immigrant population grew by 8.3 million over four years, with immigration becoming the sole driver of U.S. population growth for the first time.

The foreign-born population in the U.S. reached 53.5 million in January 2025, making up 15.8% of the total population—a record high since tracking began.
Between 2021 and 2025, the immigrant population increased by 8.3 million, with 5.4 million attributed to illegal immigration, according to new Census Bureau estimates.
Immigration accounted for all U.S. population growth from 2022 to 2023, as birthrates among American women fell to record lows, particularly among younger age groups.
Approximately 20% of the U.S. workforce is now foreign-born, and immigrants and their descendants are projected to drive all future labor force growth in the coming decades.
The Biden administration's immigration policies, including expanded legal pathways and border management changes, have been credited with accelerating this demographic shift, sparking debates about economic and social impacts.
