The 1850 United States census was the first federal U.S. census to query about the "nativity" of citizens—where they were born, either in the United States or outside of it—and is thus the first point at which solid statistics become available. From the U.S. Census , this chart shows the place of birth of the non-native population. Note that the same immigrant will be counted in each census during which they lived, so the numbers are of the cumulative number of living non-native citizens.
