Central Coast Council area

Household size

In 2011, 27% of households in the Central Coast Council area contained only one person, compared with 28% in Regional TAS, with the most dominant household size being 2 persons per household.

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 can also be influenced by a lack (or abundance) of affordable housing. Overseas migrants and indigenous persons often have a tradition of living with extended family members which significantly affects household size.

Household size in Australia has declined since the 1970s but between 2006 and 2011, the average household size remained stable for the nation as a whole.

An increasing household size in an area may indicate a lack of affordable housing opportunities for young people, an increase in the birth rate or an increase in family formation in the area. A declining household size may indicate children leaving the area when they leave home, an increase in retirees settling in the area, or an attraction of young singles and couples to the area.

For greater insight, the Central Coast Council area's Household Size data should be viewed in conjunction with Household Summary, Age Structure, Dwelling Type, 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, 9 August 2011 in this dwelling', and 'Where does the person usually live?', and 'Are there any persons who usually live in this dwelling who were absent on Census Night (Tuesday, 9 August 2011)?'
