Suicide is the second leading cause of death among adolescents between the ages of 15 and 24 years. Adolescents who are sexual minorities experience elevated rates of suicide attempts.

Can a single conversation change minds on divisive social issues, such as same-sex marriage? A randomized placebo-controlled trial assessed whether gay (n = 22) or straight (n = 19) messengers were effective at encouraging voters (n = 972) to support same-sex marriage and whether attitude change persisted and spread to others in voters' social networks. The results, measured by an unrelated panel survey, show that both gay and straight canvassers produced large effects initially, but only gay canvassers' effects persisted in 3-week, 6-week, and 9-month follow-ups. We also find strong evidence of within-household transmission of opinion change, but only in the wake of conversations with gay canvassers. Contact with gay canvassers further caused substantial change in the ratings of gay men and lesbians more generally. These large, persistent, and contagious effects were confirmed by a follow-up experiment. Contact with minorities coupled with discussion of issues pertinent to them is capable of producing a cascade of opinion change.

Marriage benefits both individuals and societies, and is a fundamental determinant of health. Until recently same sex couples have been excluded from legally recognized marriage in the United States. Recent debate around legalization of same sex marriage has highlighted for anti-same sex marriage advocates and policy makers a concern that allowing same sex couples to marry will lead to a decrease in opposite sex marriages. Our objective is to model state trends in opposite sex marriage rates by implementation of same sex marriages and other same sex unions.

Extensive data available from more than 30 years of research reveal that children raised by gay and lesbian parents have demonstrated resilience with regard to social, psychological, and sexual health despite economic and legal disparities and social stigma. Many studies have demonstrated that children’s well-being is affected much more by their relationships with their parents, their parents' sense of competence and security, and the presence of social and economic support for the family than by the gender or the sexual orientation of their parents. Lack of opportunity for same-gender couples to marry adds to families' stress, which affects the health and welfare of all household members. Because marriage strengthens families and, in so doing, benefits children’s development, children should not be deprived of the opportunity for their parents to be married. Paths to parenthood that include assisted reproductive techniques, adoption, and foster parenting should focus on competency of the parents rather than their sexual orientation.

Recent legal cases before the Supreme Court of the United States were challenging federal definitions of marriage created by the Defense of Marriage Act and California’s voter approved Proposition 8 which limited marriage to different-sex couples only. Social science literature regarding child well-being was being used within these cases, and the American Sociological Association sought to provide a concise evaluation of the literature through an amicus curiae brief. The authors were tasked in the assistance of this legal brief by reviewing literature regarding the well-being of children raised within same-sex parent families. This article includes our assessment of the literature, focusing on those studies, reviews and books published within the past decade. We conclude that there is a clear consensus in the social science literature indicating that American children living within same-sex parent households fare just, as well as those children residing within different-sex parent households over a wide array of well-being measures: academic performance, cognitive development, social development, psychological health, early sexual activity, and substance abuse. Our assessment of the literature is based on credible and methodologically sound studies that compare well-being outcomes of children residing within same-sex and different-sex parent families. Differences that exist in child well-being are largely due to socioeconomic circumstances and family stability. We discuss challenges and opportunities for new research on the well-being of children in same-sex parent families.

While the US Supreme Court was considering two related cases involving the constitutionality of same-sex marriage, one major question informing that decision was whether scientific research had achieved consensus regarding how children of same-sex couples fare. Determining the extent of consensus has become a key aspect of how social science evidence and testimony is accepted by the courts. Here, we show how a method of analyzing temporal patterns in citation networks can be used to assess the state of social scientific literature as a means to inform just such a question. Patterns of clustering within these citation networks reveal whether and when consensus arises within a scientific field. We find that the literature on outcomes for children of same-sex parents is marked by scientific consensus that they experience “no differences” compared to children from other parental configurations.

The recent Supreme Court decision in Obergefell v. Hodges, which rejected as unconstitutional state bans on same-sex marriage, was a major milestone for the lesbian, gay, bisexual, and transgender (LGBT) civil rights movement. Soon after the decision, a dental hygienist, chatting with me on an airplane, mentioned that her gay niece was getting married. “How nice,” she said, “that this is now legal everywhere. In the past, gay people were so often treated very badly!” The idea that the acceptance of same-sex marriage as part of the fundamental right to marriage heralds the end of bad treatment of LGBT people . . .

Eleven years ago, Massachusetts became the first state in the country to give same-sex marriages full legal recognition. Today, same-sex marriage is legal, through legislative or judicial action or by popular vote, in more than 35 states and the District of Columbia. It is recognized by the federal government. And polls consistently show that it is supported by a clear majority of Americans. However, in Ohio, Kentucky, Michigan, and Tennessee, the Sixth Circuit Court of Appeals has ruled in favor of laws and constitutional amendments that define marriage as a union between a man and a woman only, denying recognition . . .

Some conservative groups argue that allowing same-sex couples to marry reduces the value of marriage to opposite-sex couples. This article examines how changes in U.S. legal recognition laws occurring between 1995 and 2010 designed to include same-sex couples have altered marriage rates in the United States. Using a difference-in-differences strategy that compares how marriage rates change after legal recognition in U.S. states that alter legal recognition versus states that do not, I find no evidence that allowing same-sex couples to marry reduces the opposite-sex marriage rate. Although the opposite-sex marriage rate is unaffected by same-sex couples marrying, it decreases when domestic partnerships are available to opposite-sex couples.

BACKGROUND: Living arrangements have changed markedly in recent decades, so we wanted to provide an up-to-date assessment of mortality as a function of marital status and cohabitation status in a complete population. METHODS: We studied mortality in a national cohort of 6.5 million Danes followed for 122.5 million person-years during 1982-2011, using continuously updated individual-level information on living arrangements, socio-demographic covariates and causes of deaths. Hazard ratios (HRs) estimated relative mortality in categories of marital status, cohabitation status and combinations thereof. RESULTS: HRs for overall mortality changed markedly over time, most notably for persons in same-sex marriage. In 2000-2011, opposite-sex married persons (reference, HR = 1) had consistently lower mortality than persons in other marital status categories in women (HRs 1.37-1.89) and men (HRs 1.37-1.66). Mortality was particularly high for same-sex married women (HR = 1.89), notably from suicide (HR = 6.40) and cancer (HR = 1.62), whereas rates for same-sex married men (HR = 1.38) were equal to or lower than those for unmarried, divorced and widowed men. Prior marriages (whether opposite-sex or same-sex) were associated with increased mortality in both women and men (HR = 1.16-1.45 per additional prior marriage). CONCLUSION: Our study provides a detailed account of living arrangements and their associations with mortality over three decades, thus yielding accurate and statistically powerful analyses of public health relevance to countries with marriage and cohabitation patterns comparable to Denmark’s. Of note, mortality among same-sex married men has declined markedly since the mid-1990s and is now at or below that of unmarried, divorced and widowed men, whereas same-sex married women emerge as the group of women with highest and, in recent years, even further increasing mortality.
