Adoption of children is widespread across cultures, sometimes constituted legally, but more often through informal structures of support and sponsorship. There were an estimated 1.5 million adopted children under 18 in the United States in 2019, about 1 out of every 50 children, and adoption is increasing, especially among same-sex couples. In 2019, 43.3 percent of children of same-sex couples were adopted or stepchildren.
Across cultures, informal adoption and foster care have long been practiced to strengthen families and provide opportunities for young people. Anthropological studies in West Africa, Oceania, Latin America, and in minority communities in North America document the prevalence of these practices, as well as their benefits and risks. In general, cultures that see social relationships as open and fluid are able to provide a greater range of opportunities to children. One common form of informal adoption relocates children from rural birth families to relatives living in urban areas, where they have more opportunities for education, employment, and career training. Sometimes informal fostering helps to provide caretaking for shorter periods of time. A family may send an older child to temporarily live with a relative or even a friend who has a new infant or is facing a family crisis. These relationships may be mutually beneficial, allowing older children to meet new people and develop a wider network of friends and relatives. Historically, adoptive ties have played a major role in family security and in creating stronger social ties between families, some of which may provide future educational, work, and career opportunities.
