These statistics do not take into account the mixing of ancestries within the same "race"; e.g.
a marriage involving Indian and Japanese ancestries would not be classified as interracial due to the Census regarding both as the same category.
Likewise, since Hispanic is not a race but an ethnicity, Hispanic marriages with non-Hispanics are not registered as interracial if both partners are of the same race (i.e.
a Black Hispanic marrying a non-Hispanic Black partner).
Using the 2002 National Survey of Family Growth (Cycle VI), the likelihood of divorce for interracial couples to that of same-race couples was compared.
Comparisons across marriage cohorts revealed that, overall, interracial couples have higher rates of divorce, particularly for those that married during the late 1980s.
The study also observed a clear gender divide in racial preference with regards to marriage: Women of all the races which were studied revealed a strong preference for men of their own race for marriage, with the caveat that East Asian women only discriminated against Black and Hispanic men, and not against White men.
In terms of out-marriage, Hispanic males who identified as White had non-Hispanic wives more often than other Hispanic men.
However, a 2009 study a year later by Yaunting Zhang and Jennifer Van Hook on behalf of Journal of Marriage and Family using a larger sample size than the previous study produced different results with Asian female/White male marriages shown as the least likely to divorce of any marriage pairing.
This data comes from Table 3 Model 4 of the Zhang paper, which incorporates all controls into the model.
White husband, white wife pairings are used as a control.
The numbers are the relative rates at which interracial couples get divorced i.e.
