Immigrant Populations

About 275,000 babies were born to unauthorized-immigrant parents in 2014, a decline from 330,000 in 2009.

Long-term growth in total U.S. births has been driven by the foreign born, who accounted for 23% of all babies born in 2014.

But the U.S. and Europe are quite different when it comes to their migrant populations’ origin countries.

The UK has the fifth-largest immigrant population in the world, at 8.5 million.

Apprehensions of children and their families at the U.S.-Mexico border since October 2015 have more than doubled from a year ago and now outnumber apprehensions of unaccompanied children, a figure that also increased this year.

The immigrant population in Texas has grown rapidly in recent decades, reaching 4.5 million in 2014. That puts Texas in a tie with New York for the second largest state immigrant population by size.

Nearly six-in-ten U.S. Hispanics are Millennials or younger, making them the youngest major racial or ethnic group in the United States. In 2014, the median age of Hispanics was just 28 years.

There were a record 42.2 million immigrants living in the U.S. in 2014, making up 13.2% of the nation’s population.

This change comes after a period in which net migration of Mexicans to the U.S. had fallen to lows not seen since the 1940s.

In 2015, more than 1.8 million people crossed the European Union’s borders illegally, up from 280,000 detections of illegal border crossings in 2014.
