Unauthorized Immigrant Population: National and State Trends 2010

This statistical analysis of the undocumented population updates previous annual reports published by the Pew Research Center. At 11.2 million in 2010, Pew's estimate of the national total of undocumented immigrants remains largely unchanged from 2009. During the previous two years (2007-2009), however, the number had declined from a high of 12 million in 2007. At the same time, the 2010 numbers show significant variations among the states. The decline in unauthorized numbers was especially great in New York and Florida, while increases occurred in Texas and Louisiana. New Jersey had an estimated 550,000 unauthorized immigrants in 2010, including 400,000 in the workforce, representing 8.6% of the total state workforce: the 4th highest percentage in the country.
