This report is based primarily on two data sources: the Pew Research Center’s analysis of demographic data about new marriages in 2008 from the U.S. Census Bureau’s American Community Survey (ACS) and the Pew Research Center’s analysis of its own data from a nationwide telephone survey conducted from October 28 through November 30, 2009 among a nationally representative sample of 2,884 adults. A record 14.6% of all new marriages in the U.S in 2008 were between spouses of a different race or ethnicity from one another, according to a Pew Research Center analysis of new census data. Of all newlyweds in 2008, 9% of whites, 16% of blacks, 26% of Hispanics and 31% of Asians married outside their race/ethnicity. Patterns also varied by region (intermarriage is most common in the West) and by gender. (Author abstract)
