22 Percent

That's the number of African-American men who married a woman who was not black in 2008. Another data point: "Among all married African-Americans in 2008, 13 percent of men and 6 percent of women had a nonblack spouse. This compares with nearly half of American-born Asians choosing non-Asian spouses."
