“The number of unauthorized immigrants living in the U.S.—11.3 million in 2013—has stabilized since the end of the Great Recession in 2009, 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. In 2013, adult unauthorized immigrants had lived in the U.S. for a median time of nearly 13 years, up from 7.5 years in 2003.”
