More than one-in-six new marriages these days (15%) take place between people from different race or ethnic groups, according to a report from the Pew Research Center’s Social & Demographic Trends project that uses data from the Census Bureau’s American Community Survey. Among all marriages, 8.4% are intermarriages. Patterns vary widely by race and ethnic group, the report finds, and within each group they vary by gender. The report examines similarities and differences between couples who “marry out” and couples who “marry in,” analyzes regional differences in patterns of intermarriage, and uses Pew Research Center public opinion surveys to explore society’s changing attitudes towards couples who marry outside their race or ethnic group.
