Contrary to popular perception, the levels of migration to the United States are far from unprecedented.
The absolute numbers have never been higher. But put into relation to the overall population, the percentage share in 1910 (14.7) was higher than it is today (13.5). In 2015 some 43 million people were living in the United States who were born abroad.
The term foreign-born refers to people residing in the United States who were not U.S. citizens at birth. This includes naturalized citizens, lawful permanent residents (LPRs), certain legal nonimmigrants (like persons on student or work visas), refugees or asylum seekers and also persons illegally residing in the United States.
Visit the Migration Policy Institute for more information on all issues linked to migration.
