In 1967, when miscegenation laws were overturned in the United States, 3% of all newlyweds were married to someone of a different race or ethnicity. Since then, intermarriage rates have steadily climbed. By 1980, the share of intermarried newlyweds had about doubled to 7%. And by 2015 the number had risen to 17%.
All told, more than 670,000 newlyweds in 2015 had recently entered into a marriage with someone of a different race or ethnicity. By comparison, in 1980, the first year for which detailed data are available, about 230,000 newlyweds had done so.
The long-term annual growth in newlyweds marrying someone of a different race or ethnicity has led to dramatic increases in the overall number of people who are presently intermarried – including both those who recently married and those who did so years, or even decades, earlier. In 2015, that number stood at 11 million – 10% of all married people. The share has tripled since 1980, when 3% of married people – about 3 million altogether – had a spouse of a different race or ethnicity.
