Population and age structure

Between 2016 and 2026, the age structure forecasts for the Shire of Serpentine-Jarrahdale indicate a 62.6% increase in population under working age, a 71.0% increase in population of retirement age, and a 72.4% increase in population of working age.

Knowledge of how the age structure of the population is changing is essential for planning age-based facilities and services, such as child care, recreation and aged care.

The forecast age groups of the Shire of Serpentine-Jarrahdale is a function of the current age of the population (people aging each year, being born and dying) as well as the age of people migrating into and out of the area. This in turn is driven by location (fringe, city centre, regional or rural) the existing housing stock (separate dwellings, medium or high density), the amount and type of new residential development (same as existing stock, or diversifying) and where the area is in a cycle of change. We call this the area’s residential role and function. You can learn more about this in the section household and suburb life cycles.
