The number of interracial marriages in the U.S. has risen 20 percent since 2000 to about 4.5 million, according to the latest census figures. While still growing, that number is a marked drop-off from the 65 percent increase between 1990 and 2000.
About 8 percent of U.S. marriages are mixed-race, up from 7 percent in 2000.
The latest trend belies notions of the U.S. as a post-racial, assimilated society. Demographers cite a steady flow of recent immigration that has given Hispanics and Asians more ethnically similar partners to choose from while creating some social distance from whites due to cultural and language differences.
