Mexican-Born Population in United States 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 since 1970, a decline following the 2007-09 recession, and an uptick that began again in 2023. This tool offers data both on the numerical size of the Mexican immigrant population and its share of the overall foreign-born population.
