2012•procon.orgThis report provides estimates of the size of the unauthorized immigrant population residing
in the United States as of January 2011 by period of entry, region and country of origin, state
of residence, age, and sex. The estimates were obtained using the “residual” methodology
employed for previous estimates of the unauthorized population (see Hoefer, Rytina, and

This report provides estimates of the size of the unauthorized immigrant population residing in the United States as of January 2011 by period of entry, region and country of origin, state of residence, age, and sex. The estimates were obtained using the “residual” methodology employed for previous estimates of the unauthorized population (see Hoefer, Rytina, and Baker, 2011). The unauthorized immigrant population is the remainder or “residual” after the legally resident foreign-born population—legal permanent residents (LPRs), naturalized citizens, asylees, refugees, and nonimmigrants—is subtracted from the total foreign-born population. Data to estimate the legally resident population were obtained primarily from the Department of Homeland Security (DHS), whereas the American Community Survey (ACS) of the US Census Bureau was the source for estimates of the total foreign-born population.
The 2011 unauthorized estimates should not be compared with DHS estimates previously released for 2005–2010. Updates to population estimates used to weight the ACS had a substantial impact on changes in estimates of the foreign-born population between 2010 and 2011. The 2011 unauthorized estimates are derived from the 2010 ACS, which uses population estimates based on the 2010 Census. The 2005–2010 unauthorized estimates, however, are derived from the 2004-2009 ACS population estimates which are based on the 2000 Census. The Census Bureau urges caution in comparing population estimates that use different Census base years (US Census Bureau, 2011). According to the Pew Hispanic Center, the estimated 1.5 million person increase in the foreign-born population between the 2009 and 2010 ACS surveys would have been only 0.6 million if the 2009 ACS estimates had been based on the 2010 Census (Passel and Cohn, 2012). DHS has revised the 2010 unauthorized estimate using a foreign-born population estimate based on the most recent Census in order to provide an indication of the short term trend in the size of the unauthorized immigrant population (see METHODOLOGY AND DATA).
