The U.S. Census Bureau reported today that 11.4 million married-couple households, or 21 percent of all married-couple households in America in 2011, had at least one spouse born in another country. About 13 percent (7.3 million) of households had two foreign-born spouses, and 7 percent (4.1 million) had one native-born and one foreign-born spouse.
These statistics come from Married-Couple Households by Nativity Status: 2011, a brief that analyzes data from the Census Bureau's American Community Survey.
"The number of mixed-nativity married-couple households corresponds with the increase in immigration to the United States over the last several decades," said Elizabeth Grieco, chief of the Census Bureau's Foreign-Born Population Branch. "As the immigrant population has grown, so has the chance that a native-born person will meet and marry a foreign-born spouse."
