Household composition refers to the makeup of a household, including the number of people living together and their relationships to one another. This can include families, single individuals, or groups of unrelated people sharing a living space. Common types of household compositions are nuclear families, extended families, and single-person households. Understanding household composition is important for various reasons, such as planning for community services, housing needs, and social policies. It can also influence economic factors, like income levels and spending patterns, as different household types may have distinct financial behaviors and needs.
