Foreign-born population in the United States, 1850-2018
The foreign-born population residing in the U.S. reached a record 44.8 million, or 13.7% of the U.S. population, in 2018. This immigrant population has more than quadrupled since the 1960s, when the 1965 Immigration and Naturalization Act took effect. Though growth has begun to slow in recent years, the number of immigrants living in the United States is projected to almost double by 2065.
