The only information I could find on this is a relatively old study and I can't find any modern information on it. The subject pool was also relatively low because of the low level of interracial dating between the two. However research indicated that 50% less likely to divorce than White Male White Female, while White Female and Black Male are more than 3 times more likely to divorce than the closest runner up.
I tried to look into why, but none of the research I found gave me a substantial reason why and it seems it hasn't been properly researched and only guesswork has been done about it.
