Household size
About this topic
Household size shows how many people live in each household. It is a basic but important measure of family life, dwelling use, and the way people share housing.
This topic helps indicate demand for different dwelling sizes and can reflect life-cycle patterns, cultural norms, and affordability pressures. It is best read with household type, age structure, and dwelling type, because changes in household size can happen for very different reasons.
Interpretation notes
- This counts the number of people usually resident in the dwelling, so it describes shared living arrangements rather than dwelling size.
- Household size should be read with bedrooms or dwelling structure before drawing conclusions about crowding or housing suitability.
