Households without children
About this topic
Households without children includes couple-only households and lone person households, grouped by life stage. In this topic, life stage is based on the age of the household reference person rather than on the ages of all people in the dwelling.
This topic is useful for understanding the mix of younger adult, mid-life, and older households and the different housing and service needs they may have. It works best alongside household size, age structure, and dwelling type.
Interpretation notes
- This is a derived subset of couple-only and lone-person households, not a summary of all household types.
- The life-stage labels are based on the age of the household reference person, so they simplify the ages of everyone else in the household.
