"'Profile of the Foreign-Born Population in the United States: 2000', Current Population Reports, P23-206, presents data on a wide range of geographic, demographic, social, economic, and housing characteristics for the foreign-born population of the United States. Data for the native population are included for comparison. The data in this report for 2000 are from the March 2000 Current Population Survey (CPS) and do not include information from Census 2000 or the Census 2000 Supplementary Survey. Data for 1990 and earlier years, which are included for historical comparison, are from the decennial censuses of population. Detailed tables showing data for 2000 are presented in 'Profile of the Foreign-Born Population of the United States: 2000', PPL-145, issued in 2001. Detailed tables showing data on the foreign-born population from decennial censuses are presented in 'Historical Census Statistics on the Foreign-Born Population of the United States: 1850 to 1990', Population Division Working Paper, No. 29, issued in 1999. The reference date for data from the 1990 census is April 1. For data from the CPS, the reference dates vary depending on when the housing unit first came into the survey and on the topic. Housing units (and their occupants) in the CPS are in for 4 months, out for 8 months, and then in again for 4 months. Thus housing units in the March 2000 CPS are about equally distributed among those that first came into the survey from December 1998 to March 1999 and from December 1999 to March 2000. While data on some characteristics, including age, are updated, data on other characteristics, including length of residence in the United States and citizenship status of the foreignborn population, are not. The core of this report is 22 sections presenting information on various topics for the foreign-born population. These sections are preceded by Highlights and are followed by References and five appendixes: (A) Foreign Born and Other Terms: Definitions and Concepts, (B) Source and Accuracy of Estimates, (C) Comparison of Population Universes, (D) Nativity Questions on the Current Population Survey, and (E) Related Reports and Information."
