Pew Research: A Slight Increase in the Number of Unauthorized Immigrants in the U.S. in 2012 Relative to 2009

"The sharp decline in the U.S. population of unauthorized immigrants that accompanied the 2007-2009 recession has bottomed out, and the number may be rising again. As of March 2012, 11.7 million unauthorized immigrants were living in the United States, according to a new preliminary Pew Research Center estimate based on U.S. government data."
