Whanganui District

Household size

32% of the Whanganui District's households contained only one person, compared with 22.9% in the New Zealand, with the most dominant household size being 2 persons per household in 2013.

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.

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 Whanganui District'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, 5 March 2013 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, 5 March 2013)?'
