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.
Several studies have found that a factor which significantly affects an individual's choices with regards to marriage is socio-economic status ("SES")-- the measure of a person's income, education, social class, profession, etc.
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.
Gurung & Duong (1999) compiled a study relating to mixed-ethnic relationships ("MER"s) and same-ethnic relationships ("SER"s), concluding that individuals part of "MER"s generally do not view themselves differently from same-ethnic couples.
In Social Trends in America and Strategic Approaches to the Negro Problem (1948), Swedish economist Gunnar Myrdal ranked the social areas where restrictions were imposed on the freedom of Black Americans by Southern White Americans through racial segregation, from the least to the most important: basic public facility access, social equality, jobs, courts and police, politics and marriage.
This ranking scheme illustrates the manner in which the barriers against desegregation fell: Of less importance was the segregation in basic public facilities, which was abolished with the Civil Rights Act of 1964.
The most tenacious form of legal segregation, the banning of interracial marriage, was not fully lifted until the last anti-miscegenation laws were struck down in 1967 by the Supreme Court ruling in the landmark Loving v. Social enterprise research conducted on behalf of the Columbia Business School (2005–2007) showed that regional differences within the United States in how interracial relationships are perceived have persisted: Daters of both sexes from south of the Mason–Dixon line were found to have much stronger same-race preferences than northern daters did.
Interracial marriage in the United States has been fully legal in all U. states since the 1967 Supreme Court decision that deemed anti-miscegenation laws unconstitutional, with many states choosing to legalize interracial marriage at earlier dates.
Multiracial Americans numbered 9.0 million in 2010, or 2.9% of the total population, but 5.6% of the population under age 18.
The differing ages of individuals, culminating in the generation divides, have traditionally played a large role in how mixed ethnic couples are perceived in American society.
Interracial marriages have typically been highlighted through two points of view in the United States: Egalitarianism and cultural conservatism.
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 authors found that gender plays a significant role in interracial divorce dynamics: According to the adjusted models predicting divorce as of the 10th year of marriage, interracial marriages that are the most vulnerable involve White females and non-White males relative to White/White couples.
