Mexican-Born Population Over Time, 1850-Present

Since 1980, immigrants from Mexico have been the largest national-origin group in the United States. This line chart traces the growth of this 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, legal permanent residents, certain legal non-immigrants (e.g., refugees and persons on student or work visas), and persons illegally residing in the United States.
