in sociology and anthropology, a group of people who are united by ties of partnership and parenthood and consisting of a pair of adults and their socially recognized children. Typically, but not always, the adults in a nuclear family are married. Although such couples are most often a man and a woman, the definition of the nuclear family has expanded with the advent of same-sex marriage. Children in a nuclear family may be the couple's biological or adopted offspring.
