As Congress haggles over comprehensive immigration reform, it's worth taking a look who America's immigrant population actually is. The following infographics, compiled and designed by the Pew Research Hispanic Center, illustrate findings from its analysis of the nation’s foreign-born population. The information is based on data from the U.S. Census Bureau’s 2011 American Community Survey, which counts both legal and undocumented immigrants.
The estimated 11.1 million undocumented immigrants make up less than a third of all foreign-born residents in America. Among them, roughly 40% to 50% entered the country legally and overstayed their visas, according to 2006 Pew estimates. The majority of undocumented immigrants have lived in the country for 10 years or longer.
