A household is a group of people living together in a single dwelling, such as a house or apartment. This group can include families, roommates, or individuals who share living expenses and responsibilities. Households can vary in size and composition, ranging from a single person to large families. Households are important units in society, as they often share resources like food, utilities, and space. They can also influence economic factors, such as spending and saving habits. Understanding households helps in studying demographics, social structures, and community needs, impacting areas like education, healthcare, and urban planning.
