Up to 15 percent of opposite-sex married couples have partners of a different race or Hispanic origin, according to the U.S. Census Bureau. In a 2010 Census brief released yesterday, Households and Families: 2010, the bureau looked at the growth of interracial and interethnic married couples. That number has grown nationally by 28 percent over the decade -- from 7 percent in 2000 to 10 percent in 2010.
New Jersey is right around the national average, with 10 percent to 15 percent interracial and interethnic married couples making up opposite-sex married couple households.
A higher percentage of unmarried partners were interracial or interethnic than married couples. States with higher percentages of couples of a different race or Hispanic origin in 2010 – 25 percent or more -- were primarily located in the western and southwestern parts of the United States, along with Hawaii and Alaska.
