Same-sex marriage and the family

Concerns regarding same-sex marriage and the family are at the forefront of the controversies over legalization of same-sex marriage. In the United States, an estimated 1 million to 9 million children have at least one lesbian or gay parent. Concern for these children and others to come are the basis for both opposition to and support for marriage for LGBT couples.

Scientific research has been 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 published in prestigious peer-reviewed journals and statements of mainstream professional associations, there is no evidence to the contrary. The American Psychological Association reports that some studies suggest parenting skills of gays and lesbians might be "superior." Biblarz and Stacey state that while research has found that families headed by (at least) two parents are generally best for children, outcomes of more than two parents (as in some cooperative stepfamilies, intergenerational families, and coparenting alliances among lesbians and gay men) have not yet been studied.

As noted by Professor Judith Stacey of New York University: “Rarely is there as much consensus in any area of social science as in the case of gay parenting, which is why the American Academy of Pediatrics and all of the major professional organizations with expertise in child welfare have issued reports and resolutions in support of gay and lesbian parental rights”. Among these mainstream organizations in the United States are the American Psychiatric Association, the National Association of Social Workers, Child Welfare League of America, the American Bar Association, the North American Council on Adoptable Children, the American Academy of Pediatrics, the American Psychoanalytic Association and the American Academy of Family Physicians.
