However, a growing literature describing the challenges faced by interracial couples (e.g., Chito Childs, 2005; Dalmage, 2000; Killian, 2003; Lewis & Yancey, 1995; Root, 2001) suggests that crossing racial lines still violates enduring norms of who should and should not marry whom (Killian). Demographic evidence further supports this hypothesis.
For example, Bramlett and Mosher (2002) found that 41% of interracial couples divorced by the 10th year of marriage compared to only 31% of same-race couples. Their findings imply that, although entering an interracial marriage tends to carry less social stigma, these relationships are less likely to remain intact.
