Opinion of the Court
(quoting Meyer, supra, at 399). Under the laws of the several States, some of marriage’s protections for children and families are material. But marriage also confers more profound benefits. By giving recognition and legal structure to their parents’ relationship, marriage allows children “to understand the integrity and closeness of their own family and its concord with other families in their community and in their daily lives.” Windsor, supra, at ___ (slip op., at 23). Marriage also affords the permanency and stability important to children’s best interests. See Brief for Scholars of the Constitutional Rights of Children as Amici Curiae 22–27.
As all parties agree, many same-sex couples provide loving and nurturing homes to their children, whether biological or adopted. And hundreds of thousands of children are presently being raised by such couples. See Brief for Gary J. Gates as Amicus Curiae 4. Most States have allowed gays and lesbians to adopt, either as individuals or as couples, and many adopted and foster children have same-sex parents, see id., at 5. This provides powerful confirmation from the law itself that gays and lesbians can create loving, supportive families.
Excluding same-sex couples from marriage thus conflicts with a central premise of the right to marry. Without the recognition, stability, and predictability marriage offers, their children suffer the stigma of knowing their families are somehow lesser. They also suffer the significant material costs of being raised by unmarried parents, relegated through no fault of their own to a more difficult and uncertain family life. The marriage laws at issue here thus harm and humiliate the children of same-sex couples. See Windsor, supra, at ___ (slip op., at 23).
