Migrant worker

A report by the Center for Migration Studies, a MacArthur grantee, finds that the undocumented immigrant population in the United States has fallen below 11 million, continuing a nearly decade-long decline that has potential to reshape the debate over reforming the nation’s immigration system. The report also shows that naturalized citizen populations in almost every U.S. state are growing, and the legally resident foreign-born population from Mexico has grown faster than the undocumented population from the country since 1980.
