Although the anti-miscegenation laws have been revoked by the Warren Court in 1967, the social stigma related to black interracial marriages still exists in today's society although to a much lesser degree. Research by Tucker and Mitchell-Kerman from 1990 has shown that black Americans intermarry far less than any other non-White group and in 2010, only 17.1% of black Americans married interracially, a rate far lower than the rates for Hispanics and Asians. Black interracial marriages in particular engender problems associated with racist attitudes and perceived relational inappropriateness. There is also a sharp gender imbalance to Black interracial marriages: In 2008, 22% of all black male newlyweds married interracially while only 9% of black female newlyweds married outside their race, making them one of the least likely of any race or gender to marry outside their race and the least likely to get married at all.
