LINCOLN, Neb. (AP) — A report from the U.S. Census Bureau says Nebraska’s foreign-born population ranks among the youngest in the nation.

The bureau released the American Community Survey Thursday, listing the median age of people living in Nebraska but born in another country as 36.5. That makes the state’s immigrant population the sixth-youngest in the country. The national average age is 42.6.

The survey includes statistics from 2010 to 2014.

David Drozd, research coordinator for the Center for Public Affairs Research at the University of Nebraska at Omaha, evaluated the data and says that Iowa has the third-lowest average age of foreign-born residents, trailing North Dakota and South Dakota.

Drozd says having a higher concentration of younger residents keeps the state’s birth rates strong.
