What does racial identity mean in twenty-first-century America? Some say we live in a “postracial” world, and increasing numbers of Americans have multiethnic backgrounds. We academics recognize that race is a social construction, yet Americans remain attached to traditional racial categories. In 2008, approximately 15% of all marriages in the United States were interracial, and beginning with the 2000 census, Americans have been allowed to check more than one racial category. Yet 97% of Americans in 2010 reported only one race. We are proud of electing our first “black president” even though his mother was white and he grew up barely knowing his African father.
