Population projections

According to the latest available projections (which are based on several combinations of assumptions reflecting past trends in births, deaths and migration), the total population of Australia is likely to have increased to between 22.3 and 23.3 million by 2021.

The projected population will increase at a declining rate. The average annual growth rate is predicted to be between 0.5 and 0.8 during 2011—2021. Without overseas migration, the projected total population should peak at about 23.3 million in 2041, and then start to decline marginally.

Age distribution

The projected population will age progressively due to the increasing proportion of the elderly and the decreasing proportion of children . In brief, the number of persons aged under 15 is projected to be between 3.7 and 4.1 million in 2031; the population of working age (15-64 years) is projected to increase to between 14.4 and 15.0 million in 2031; and the number of persons aged 65 years or more is projected to increase to between 2.94 and 2.98 million in 2031. The projections also show significant increases in the number of persons aged 80 years or more.
