providing legal protections for same-sex couples). Polls consistently show continually rising support for the recognition of same-sex marriage in all developed democracies and in many developing countries.
Scientific studies show that the financial, psychological, and physical well-being of gay people is enhanced by marriage, and that the children of same-sex parents benefit from being raised by married same-sex couples within a marital union that is recognized by law and supported by societal institutions. At the same time, no harm is done to the institution of marriage among heterosexuals. Social science research indicates that the exclusion of same-sex couples from marriage stigmatizes and invites public discrimination against gay and lesbian people, with research repudiating the notion that either civilization or viable social orders depend upon restricting marriage to heterosexuals. Same-sex marriage can provide those in committed same-sex relationships with relevant government services and make financial demands on them comparable to that required of those in opposite-sex marriages, and also gives them legal protections such as inheritance and hospital visitation rights. Opposition is often based on religious teachings, such as the view that marriage is meant to be between men and women, and that procreation is the natural goal of marriage.[Catechism of the Catholic Church, § 2357-9](_blank)
cf. Catechism of the Catholic Church, 2351, 2391, 2396 Other forms of opposition are based on claims such as that homosexuality is unnatural and abnormal, that the recognition of same-sex unions will promote homosexuality in society, and that children are better off when raised by opposite-sex couples. These claims are refuted by scientific studies, which show that homosexuality is a natural and normal variation in human sexuality, that sexual orientation

prohibited homosexual relations, and the Hebrews were warned not to "follow the acts of the land of Egypt or the acts of the land of Canaan" (Lev. 18:22, 20:13). The Sifra clarifies what these ambiguous "acts" were, and that they included marriage between same-sex couples: "A man would marry a man and a woman a woman, a man would marry a woman and her daughter, and a woman would be married to two men."

International court rulings
European Court of Human Rights
In 2010, the European Court of Human Rights
The European Court of Human Rights (ECtHR), also known as the Strasbourg Court, is an international court of the Council of Europe which interprets the European Convention on Human Rights (ECHR). The court hears applications alleging that a co ...
(ECHR) ruled in '' Schalk and Kopf v Austria'', a case involving an Austrian same-sex couple who were denied the right to marry. The court found, by a vote of 4 to 3, that their human rights had not been violated. The court further stated that same-sex unions are not protected under art. 12 of ECHR ("Right to marry"), which exclusively protects the right to marry of opposite-sex couples (without regard if the sex of the partners is the result of birth or of sex change), but they are protected under art. 8 of ECHR ("Right to respect for private and family life") and art. 14 ("Prohibition of discrimination").
Article 12 of the European Convention on Human Rights Article 12 of the European Convention on Human Rights (ECHR) provides for two constituent rights: the right to marry and the right to found a family. With an explicit reference to ‘national laws governing the exercise of this right’, Article 12 ...
states that: "Men and women of marriageable age have the right to marry and to found a family, according to the national laws governing the exercise of this right", not limiting marriage to those in a heterosexual relationship. However, the ECHR stated in ''Schalk and Kopf v Austria'' that this provision was intended to limit marriage to heterosexual relationships, as it used the term "men and women" instead of "everyone". Nevertheless, the court accepted and is considering cases concerning same-sex marriage recognition, e.g. ''Andersen v Poland''. In 2021, the court ruled in '' Fedotova and Others v. Russia''—followed by later judgements concerning other member states—that countries must provide some sort of legal recognition to same-sex couples, although not necessarily marriage.

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. 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
, 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.[Herek, Gregory M. "Legal recognition of same-sex relationships in the United States: A social science perspective." ''American Psychologist,'' Vol 61(6), September 2006, pp. 607–21.] Studies in the United States have correlated legalization of same-sex marriage to lower rates of HIV infection, psychiatric disorders, and suicide rate in the LGBT population.
Issues
While few societies have recognized same-sex unions as marriages, the historical and anthropological record reveals a large range of attitudes towards same-sex unions ranging from praise, through full acceptance and integration, sympathetic toleration, indifference, prohibition and discrimination, to persecution and physical annihilation. Opponents of same-sex marriages have argued that same-sex marriage, while doing good for the couples that participate in them and the children they are raising, undermines a right of children to be raised by their biological mother and father. Some supporters of same-sex marriages take the view that the government should have no role in regulating personal relationships, while others argue that same-sex marriages would provide social benefits to same-sex couples. The debate regarding same-sex marriages includes debate based upon social viewpoints as well as debate based on majority rules, religious convictions, economic arguments, health-related concerns, and a variety of other issues.
Parenting
Scientific literature indicates that parents' financial, psychological and physical well-being is enhanced by marriage and that children benefit from being raised by two parents within a legally recognized union (either a mixed-sex or same-sex union). As a result, professional scientific associations have argued for same-sex marriage to be legally recognized as it will be beneficial to the children of same-sex parents or carers.
Scientific research has been generally consistent in showing that lesbian and gay parents are as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as children reared by heterosexual parents. According to scientific literature reviews, there is no evidence to the contrary.

of children by those couples with the exception of Ecuador and a third of states in Mexico, though such restrictions have been ruled unconstitutional in Mexico. In addition, Bolivia, Croatia and Israel, which do not recognize same-sex marriage, nonetheless permit joint adoption by same-sex couples. Some additional states do not recognize same-sex marriage but allow stepchild adoption by couples in civil unions, namely the Czech Republic and San Marino.
Transgender and intersex people
The legal status of same-sex marriage may have implications for the marriages of couples in which one or both parties are transgender

The opposite of ''transgender'' is ''cisgender'', which describes perso ...

Intersex people are those born with any of several sex characteristics, including chromosome patterns, gonads, or genitals that, according to the Office of the United Nations High Commissioner for Human Rights, "do not fit typical binar ...
individuals may be prohibited from marrying partners of the "opposite" sex or permitted to marry partners of the "same" sex due to legal distinctions. In any legal jurisdiction where marriages are defined without distinction of a requirement of a male and female, these complications do not occur. In addition, some legal jurisdictions recognize a legal and official change of gender, which would allow a transgender male or female to be legally married in accordance with an adopted gender identity.
In the United Kingdom, the '' Gender Recognition Act 2004'' allows a person who has lived in their chosen gender for at least two years to receive a gender recognition certificate officially recognizing their new gender. Because in the United Kingdom marriages were until recently only for mixed-sex couples and civil partnerships are only for same-sex couples, a person had to dissolve their civil partnership before obtaining a gender recognition certificate, and the same was formerly true for marriages in England and Wales, and still is in other territories. Such people are then free to enter or re-enter civil partnerships or marriages in accordance with their newly recognized gender identity. In Austria, a similar provision requiring transsexual people to divorce before having their legal sex marker corrected was found to be unconstitutional in 2006. In Quebec, prior to the legalization of same-sex marriage, only unmarried people could apply for legal change of gender. With the advent of same-sex marriage, this restriction was dropped. A similar provision including sterilization also existed in Sweden, but was phased out in 2013. In the United States, transgender and intersex marriages was subject to legal complications. As definitions and enforcement of marriage are defined by the states, these complications vary from state to state, as some of them prohibit legal changes of gender.

'', couples in same-sex marriages could only obtain a divorce in jurisdictions that recognized same-sex marriages, with some exceptions.
Judicial and legislative
There are differing positions regarding the manner in which same-sex marriage has been introduced into democratic jurisdictions. A " majority rules" position holds that same-sex marriage is valid, or void and illegal, based upon whether it has been accepted by a simple majority of voters or of their elected representatives.[ archived here.]

view holds that the institution can be validly created through the ruling of an impartial judiciary carefully examining the questioning and finding that the right to marry regardless of the gender of the participants is guaranteed under the civil rights laws of the jurisdiction.
Public opinion
Numerous polls and studies on the issue have been conducted. A trend of increasing support for same-sex marriage has been revealed across many countries of the world, often driven in large part by a generational difference in support. Polling that was conducted in developed democracies in this century shows a majority of people in support of same-sex marriage. Support for same-sex marriage has increased across every age group, political ideology, religion, gender, race and region of various developed countries in the world.
Various detailed polls and studies on same-sex marriage that were conducted in several countries show that support for same-sex marriage significantly increases with higher levels of education and is also significantly stronger among younger generations, with a clear trend of continually increasing support.

Countries with the greatest absolute difference are placed to the left in the following chart. Countries without a significant generational difference are placed to the right.
A 2016 survey by the Varkey Foundation found similarly high support of same-sex marriage (63%) among 18–21-year-olds in an online survey of 18 countries around the world.
(The sampling error is approx. 4% for Nigeria and 3% for the other countries. Because of legal constraints, the question on same-sex marriage was not asked in the survey countries of Russia and Indonesia.)
