The removal of the quota system with the Immigration and Nationality Act of 1965 opened the door to the third wave—a mix of people seeking family reunification, education and employment opportunities, and safety from war and persecution. Post-1965 MENA immigrants had a similar level of education to those in the second wave, but were far more numerous. And a much higher percentage was Muslim. Between 1980 and 2010, the size of the MENA immigrant population increased four-fold, from 223,000 to 861,000; and between 2010 and 2013 increased a further 18 percent, to 1,017,000.
