Housing
Dwelling type
About this topic
Dwelling type shows the structure of dwellings, such as separate houses, medium density housing, and higher density housing. It is a core measure of built form and residential density within an area.
This topic helps explain the housing role of an area and the kinds of households it may attract. It is best read with household size, household type, tenure, and age structure, because built form and population characteristics are closely related.
Interpretation notes
- Dwelling structure describes the physical form of dwellings counted on Census night rather than tenure, housing condition, or household makeup.
- It is strongest when read alongside household size and tenure, because structure alone does not show who lives there.
