From Pew Research:

One-in-six newlyweds (17%) were married to someone of a different race or ethnicity in 2015. This reflects a steady increase in intermarriage since 1967, when just 3% of newlyweds were intermarried, according to a 2017 Pew Research Center analysis.

While Asian (29%) and Hispanic (27%) newlyweds are most likely to intermarry in the U.S., the most dramatic increases in intermarriage have occurred among black newlyweds, 18% of whom married someone of a different race or ethnicity, up from 5% in 1980. About one-in-ten white newlyweds (11%) are married to someone of a different race or ethnicity.

Among both Gen Zers and Millennials, 53% say people of different races marrying each other is a good thing for our society, compared with 41% of Gen Xers, 30% of Boomers and 20% of those in the Silent Generation, according to the Center’s 2019 report.
