U.S. Immigrant Population Change by Decade, 1850-2024

The net change is determined by increases resulting from new immigration and decreases resulting from immigrant mortality or emigration. The chart also displays changes for the 2014–24 decade.
Notes
1. The term "immigrants" (also known as the foreign born) refers to people residing in the United States who were not U.S. citizens at birth. This population includes naturalized citizens, lawful permanent residents (LPRs), certain legal nonimmigrants (e.g., persons on student or work visas), those admitted under refugee or asylee status, and persons illegally residing in the United States.
2. The U.S. Census Bureau experienced significant challenges collecting data in 2020 due to the COVID-19 pandemic and released only a small number of data points from its 2020 American Community Survey (ACS), which it called “experimental.” This data tool does not include estimates from the 2020 ACS.
