Fifty years after passage of the landmark law that rewrote U.S. immigration policy, nearly 59 million immigrants have arrived in the United States, pushing the country’s foreign-born share to a near record 14%. For the past half-century, these modern-era immigrants and their descendants have accounted for just over half the nation’s population growth and have reshaped its racial and ethnic composition.
Looking ahead, new Pew Research Center U.S. population projections show that if current demographic trends continue, future immigrants and their descendants will be an even bigger source of population growth. Between 2015 and 2065, they are projected to account for 88% of the U.S. population increase, or 103 million people, as the nation grows to 441 million.
As a result of its changed makeup and rapid growth, new immigration since 1965 has altered the nation’s racial and ethnic composition. In 1965, 84% of Americans were non-Hispanic whites. By 2015, that share had declined to 62%. Meanwhile, the Hispanic share of the U.S. population rose from 4% in 1965 to 18% in 2015. Asians also saw their share rise, from less than 1% in 1965 to 6% in 2015.
The Pew Research analysis shows that without any post-1965 immigration, the nation’s racial and ethnic composition would be very different today: 75% white, 14% black, 8% Hispanic and less than 1% Asian.
