NOTES: Data for 1970, 1980, and 1990 are based on the U.S. resident population, enumerated from the decennial censuses. Prior to 1994, the decennial census was the sole source for the foreign-born population. Starting in 1994, data are for the U.S. civilian noninstitutionalized population from the Current Population Survey, March Supplements, which began collecting data on nativity, citizenship, year-of-entry, and parental nativity of respondents. Because of theses changes, the data in this table slightly understate the growth in the foreign-born population in the years after 1994. See Appendix II, Foreign-born persons. Estimates for foreign-born persons include immigrants (legal permanent residents), temporary migrants (e.g., students, visiting scientists), humanitarian migrants (e.g., refugees), and unauthorized migrants (people illegally residing in the United States).
