The U.S. Hispanic population reached a record 59.9 million in 2018, up from 2017. Population growth among Latinos has slowed since the 2000s.
More than 40 million people living in the U.S. were born in another country, accounting for about one-fifth of the world’s migrants in 2017.
Recently arrived immigrants have markedly different education, income and other characteristics from those who have been in the U.S. for longer.
In 2016, the 20 U.S. metro areas with the most unauthorized immigrants were home to 6.5 million of them, or 61% of the estimated total.

About 250,000 babies were born to unauthorized immigrant parents in the United States in 2016, the latest year for which information is available, according to a new Pew Research Center analysis of government data about illegal immigration. This represents a 36% decrease from a peak of about 390,000 in 2007.
Lawful immigrants account for three-quarters of the foreign-born population in the U.S. – 33.8 million people out of 44.7 million people in 2015.
Despite its slowing growth rate, the U.S. Hispanic population continues to expand, reaching a record 58.6 million in 2017.
While 67% of lawful immigrants eligible for naturalization had applied for and obtained U.S. citizenship by 2015, this share was only 42% among Mexicans.
