United States immigration statistics

The 1850 United States census was the first federal U.S. census to query respondents about their "nativity"&mdash;i.e, where they were born, whether in the United States or outside of it&mdash;and is thus the first point at which solid statistics become available. The following chart, based on statistics from the U.S. Census from 1850 on, shows the numbers of non-native residents according to place of birth. Because an immigrant is counted in each census during his or her lifetime, the numbers reflect the cumulative population of living non-native residents.
