Has the foreign-born share of the US population reached a record high?
Core argument: The U.S. foreign-born population rose by 8.3 million from January 2021 to January 2025, a larger four-year increase than any other four-year period in American history and larger than the 7.9 million increase over the prior 12 years.
The numerical increase of 8.3 million in the last four years is larger than in any four-year period in American history. The 8.3 million increase in the four years from January 2021 to January 2025 is also larger than the 7.9 million increase in the 12 years prior. At 53.3 million and 15.8 percent of the population, the foreign-born population is higher now than at any time in American history. The number of immigrants has increased more than five-fold since 1970, and nearly three-fold since 1990, and by more than two-thirds since 2000. As a share of the population, even in 1890 (14.8%) and 1910 (14.7%) during what is often called the “Great Wave” of immigration, the foreign-born were a smaller share of the population than they are today.
