Since the passage of the landmark Immigration and Nationality Amendments of 1965, New York's foreign-born population has more than doubled to 3 milliona population that would comprise the third largest city in the U.S., bested by just New York City and Los Angeles. The surge in the foreign-born has been accompanied by a decline in the share of immigrants from Europe, from 64 percent in 1970 to just 16 percent in 2011. Latin America is now the largest area of origin, comprising nearly one-third of the city's foreign-born, followed by Asia (28 percent), and the nonhispanic Caribbean (19 percent). Africa accounts for 4 percent. New York arguably boasts the most diverse population of any major city in the world because of the fl ow of immigrants from across the globe.
