Analyzing Poll Data On Interracial Marriage Equality

In 1948, the California Supreme Court ruled in Perez v Sharp that the state's prohibition on interracial marriages was invalid. That was the first state Supreme Court decision to strike down an anti-miscegenation statute. 10 years later a national poll of Americans by Gallup in September 1958 showed that 94% of respondents disapproved of "marriages between blacks and whites." The United States Supreme Court did not invalidate all remaining laws banning interracial marriage (which were still on the books in 16 states) until 1967, and a year later a mere 20 percent of respondents approved of interracial marriages (73 percent disapproved) in a June 1968 Gallup poll. It was not until the mid-1990s that a majority of poll respondents said that they approved of interracial marriage equality.

In 2004, the Massachusetts Supreme Court decision Goodridge v. Department of Public Health went into effect, legalizing marriages between same-sex couples on May 17. At the time 42% of Americans approved of marriage equality, with 55 percent disapproving of civil marriages between same-sex couples. As I noted yesterday, it is only in 2011 that Gallup has shown majority support for marriage equality nationwide, even though there are only 5 states and the District of Columbia where the practice is legal.
