LEARN MORE ABOUT .idBetween 2021 and 2031, the age structure forecasts for Mount Druitt indicate a 16.1% decrease in males under working age, a 54.3% increase in males of retirement age, and a 1.2% decrease in males 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 Blacktown City Council 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.
