A new study from the Pew Research Center found that one in 12 new marriages are between interracial couples, climbing to 4.8 million couples.
Interracial unions account for about 8.5 percent of total marriages in the U.S., up from 3 percent in 1980.
In all, more than 15 percent of new marriages in 2010 were interracial.
"The rise in interracial marriage indicates that race relations have improved over the past quarter century," Daniel Lichter, a sociology professor at Cornell University told The Associated Press.
"Mixed-race children have blurred America's color line. They often interact with others on either side of the racial divide and frequently serve as brokers between friends and family members of different racial backgrounds," he said. "But America still has a long way to go."
The study shows an increase in Asian and Hispanic immigrants is one factor. Also African Americans are now more likely to marry whites.
The study says interracial unions and the mixed-race children they produce are changing typical notions of race.
