Population growth is important to measure. It can aid in the development of plans and policies for individual cities or counties. It can also help develop the country as a whole ensuring that there is enough capacity to meet the housing needs of the population.
Average household sizes can be a reflection of personal or cultural preferences or economic choices. Anticipating changes in the size and composition of households is important for many housing-related issues and associated policies, including the needs of elderly single-person households, intergenerational housing options, and housing types to meet all life cycles. Broadly, the changing composition of households may create a demand for the design and price of new housing types.
