For example, a study by the Centre for Behaviour and Evolution, Newcastle University confirmed that women show a tendency to marry up in socio-economic status; this reduces the probability of marriage of low SES men.
Anti-miscegenation laws discouraging marriages between Whites and non-Whites were affecting Asian immigrants and their spouses from the late 17th to early 20th century.
The table shows that among whites who out-married in 2008, there were different patterns by gender in the race of their spouses.
More than a quarter of white men (26.9%) married an Asian woman, and about 6.9% married a black woman.
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.
