Since 1965, when Congress overhauled the nation’s immigration law, the Hispanic population in America has jumped from just under 10 million to more than 50 million in recent years, including about 9.6 million illegal immigrants from Latin America as of 2008, according to the report.
But, according to a new study, the era of mass migration from Mexico appears, for the moment, to be over. Apprehensions of unauthorized border crossers were at the lowest point in decades last year. Legal entries also dropped from 219,000 in 2002 to 139,000 in 2010.
