Morality, Equality, or Locality: Analyzing the Determinants of Support for Same-sex Marriage

In this article, the authors develop a model in which they depict individuals’ support for same-sex marriage as a function of several clusters of independent variables, including symbolic politics, moral and religious attitudes and attachments, feelings toward gays and lesbians, women’s rights and gender roles, concern for minority and civil rights, demographic attributes, and the local context. Using data from the 2004 American National Election Studies survey and the U.S. Census, the authors find that attitudes toward same-sex marriage are a function of moral and religious considerations, attitudes toward gays and lesbians, and gender roles. They find little evidence that attitudes toward women’s rights and civil rights for African Americans affect attitudes toward same-sex marriage. Finally, they find that contextual effects are limited only to those respondents who reside in counties with a very high percentage of same-sex partnered couples.
