Population and dwellings

reset

The Census usual resident population of Aldinga - Port Willunga in 2021 was 2,553, living in 1,433 dwellings with an average household size of 2.20.

There are a number of different ways of measuring the population of an area, all of which give an insight into the size of the place and its rate of growth over different time periods. The Census counts people where they are on the night of the Census (Enumerated population) and also by where they usually live (Usual residence). Both these populations are useful and form the basis for a range of characteristics collected in the Census.

However, the most accurate count of the total population is Estimated Resident Population, which factors in an estimate of those missed in the Census and those who were overseas on Census night. It is usually higher than either Census count, and is also updated annually after the Census, providing preliminary estimates for up to 5 years.

This page provides the three population counts for Aldinga - Port Willunga at the last Census, with comparisons to previous Census years for the Census counts only.
