Final answer:
In Japan, a stem household typically includes the parents and one of their married children with their spouse and children. This contrasts with a nuclear family, which consists of only the parents and their children.
Step-by-step explanation:
In Japan, a stem household typically includes the parents and one of their married children—with spouse and children—living together. This family structure is a variation of the extended family, which broadly consists of at least one parent and child as well as other relatives, such as grandparents, aunts, uncles, and cousins. The stem household contrasts with a nuclear family, comprised of only the parents and their immediate children within the same household. Considering global family dynamics, we observe that the majority of U.S. children live in two-parent households, yet this structure does not necessarily depict the entire spectrum of family arrangements present in society due to the prevalence of other forms such as single-parent households, cohabiting parents, and extended family living arrangements.
