U.S. Immigrant Population and Share over Time, 1850-Present

This chart displays both the number of immigrants residing in the United States and their share of the total U.S. population over time.

Notes: 

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.
