From 2009 to 2012, the population of unauthorized immigrants rose in seven states and fell in 14. Losses in 13 states were due to drops in the number of unauthorized immigrants from Mexico.
The number of unauthorized immigrants living in the United States has stabilized since the end of the Great Recession and shows no sign of rising, according to new Pew Research Center estimates. The marked slowdown in new arrivals means that those who remain are more likely to be long-term residents, and to live with their U.S.-born children.
