Northern Beaches Council area
Overseas born - Household size
In the Northern Beaches Council area, 30.1% of people [Toggles].[COIIDDisplayLabel] were found in households with 2 persons.
The size of households in general follows the life-cycle of families. Households are usually small at the stage of relationship formation (early marriage), and then increase in size with the advent of children. They later reduce in size again as these children reach adulthood and leave home.
Household size may differ significantly for overseas-born populations. Some cultural groups may be affected by the availability of affordable housing, and may have a preference for living in larger households with extended family members. On the other hand recent arrivals in student housing may have mainly 1 and 2 person households.
A comparison with Dwelling Type and Number of Bedrooms data may indicate whether overcrowding is an issue for overseas-born populations. Please note however that multiple overseas-born people in a household will be counted multiple times in this topic.
Household size should be viewed in conjunction with Household Type, Age Structure, Household Income and Language Spoken at Home.
Derived from the three Census questions:
'Name of each person including visitors who spent the night of Tuesday, 10 August 2021 in this dwelling', and 'Where does the person usually live?', and 'Name of each person who usually lives in this dwelling but was away on Tuesday, 10 August 2021.'
