Which family structure typically includes children raised by one biological parent and extended family?

The family structure that includes children raised by one biological parent and extended family is often identified as multigenerational families. In multigenerational families, multiple generations live together or support each other, which frequently includes grandparents, aunts, uncles, and other relatives playing significant roles in the upbringing of the children. This family dynamic can provide a supportive environment, where the extended family offers emotional, financial, and practical assistance to the single biological parent.

In contrast, foster families are usually formed when a child is placed with caregivers who are not their biological parents, and blended families typically arise from the merging of two separate families due to remarriage or cohabitation, thus including stepsiblings. Single-parent families specifically denote households led by one parent without any implication of extended family members being involved in the child's upbringing, which is why they do not align with the description provided in the question.
