For purposes of defining interracial marriages, Hispanic is counted as a race by many in the demographic field. While Hispanics and Asians remained the most likely, as in previous decades, to marry someone of a different race, the biggest jump in share since 2008 occurred among blacks, who historically have been the most segregated.
