Same-sex marriage

== Studies ==
The [[American Anthropological Association]] stated on 26 February 2004:{{blockquote|text=The results of more than a century of anthropological research on households, kinship relationships, and families, across cultures and through time, provide no support whatsoever for the view that either civilization or viable social orders depend upon marriage as an exclusively heterosexual institution. Rather, anthropological research supports the conclusion that a vast array of family types, including families built upon same-sex partnerships, can contribute to stable and humane societies.<ref name="aaa">{{Cite web |last=American Anthropological Association |author-link=American Anthropological Association |year=2004 |title=Statement on Marriage and the Family |url=http://www.aaanet.org/issues/policy-advocacy/Statement-on-Marriage-and-the-family.cfm |url-status=live |archive-url=https://web.archive.org/web/20150912104755/http://www.aaanet.org/issues/policy-advocacy/Statement-on-Marriage-and-the-Family.cfm |archive-date=12 September 2015 |access-date=18 September 2015}}</ref>}}

The overall socio-economic and health effects of legal access to same-sex marriage around the world have been summarized by Badgett and co-authors. <ref>{{Cite journal |doi = 10.1002/pam.22587|title = A review of the effects of legal access to same-sex marriage |journal = Journal of Policy Analysis and Management|year = 2024|last1=Badgett|first1=M.V. Lee|last2=Carpenter|first2=Christopher S.|last3=Lee|first3=Maxine J.|last4=Sansone|first4 = Dario|doi-access=free}}</ref> The review found that sexual minority individuals took-up legal marriage when it became available to them (but at lower rates than different-sex couples). There is instead no evidence that same-sex marriage legalization affected different-sex marriages. On the health side, same-sex marriage legalization increased health insurance coverage for individuals in same-sex couples (in the US), and it led to improvements in sexual health among men who have sex with men, while there is mixed evidence on mental health effects among sexual minorities. In addition, the study found mixed evidence on a range of downstream social outcomes such as attitudes toward LGBTQ+ people and employment choices of sexual minorities.

===Health===

{{as of|2006}}, the data of current psychological and other social science studies on same-sex marriage in comparison to mixed-sex marriage indicate that same-sex and mixed-sex relationships do not differ in their essential psychosocial dimensions; that a parent's sexual orientation is unrelated to their ability to provide a healthy and nurturing family environment; and that marriage bestows substantial psychological, social, and health benefits. Same-sex parents and carers and their children are likely to benefit in numerous ways from legal recognition of their families, and providing such recognition through marriage will bestow greater benefit than civil unions or domestic partnerships.<ref name="aap2006" /><ref name="autogenerated4">Herek, Gregory M.
