摘要

This report provides estimates of the size of the unauthorized immigrant population residing in the United States as of January 2010 by period of entry, region and country of origin, state of residence, age, and gender. The estimates were obtained using the residual methodology employed for estimates of the unauthorized population in 2009. The unauthorized resident population is the remainder or residual after estimates of the legally resident foreign-born populationlegal permanent residents (LPRs), naturalized citizens, asylees, refugees, and nonimmigrantsare subtracted from estimates of the total foreign-born population. Data to estimate the legally resident population were obtained primarily from the Department of Homeland Security (DHS) while the American Community Survey (ACS) of the U.S. Census Bureau was the source for estimates of the total foreign-born population.
