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.
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.
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.
Public approval of interracial marriage rose from around 5% in the 1950s to around 80% in the 2000s.
The proportion of interracial marriages is markedly different depending on the ethnicity and gender of the spouses.
Interracial marriage in the United States has been legal in all U. states since the 1967 Supreme Court decision Loving v.
