Wellington Region

Service age groups

the Wellington Region had a lower proportion of pre-schoolers and a lower proportion of people at post retirement age than North Island in 2018.

The Age Structure of the population is the most widely used component of the Census. It is an indicator of an area’s residential role and function and how it is likely to change in the future. the Wellington Region's age demographics are indicative of the area’s era of settlement and provide key insights into the level of demand for services and facilities (as most services and facilities are age-specific).

Service age groups divide the population into age categories that reflect typical life-stages. They indicate the level of demand for services that target people at different stages in life and how that demand is changing.

To get a more complete picture of the Wellington Region's demographic characteristics, the Wellington Region's Age Structure should be viewed in conjunction with Family and Household type data.
