Projection

Values for 2050 come from the UN World Population Prospects 2024 medium scenario. They depend on assumptions about fertility, mortality, and migration and are not forecasts guaranteed to occur.

What to notice in 2050

Still a gently tapering column; growth continues, yet the bands above 75 are much broader than in 2026. Read the full analysis of Australia’s pyramid.

Australia age structure in 2050

In 2050, children under 15 are projected to make up 15.7% of the population, people aged 15–64 60.4%, and people aged 65 or older 23.9%. On these shares the structure is classed as older; see the guide to constrictive population pyramids.

The total age dependency ratio is projected to be 65.4 (26.0 children and 39.5 people aged 65+ per 100 aged 15–64). The largest five-year groups are 35–39, 30–34, 25–29, which together account for 19.3% of the population.

Fertility is projected to be 1.64 births per woman and life expectancy at birth 87.2 years. The population is projected to change by +0.65% during the year.

Australia in 2050 compared with 2026

Between 2026 and 2050, the medium scenario has Australia’s population growing by 19% and the median age rising by 3.5 years. The table sets the two years side by side; percentage-point differences compare shares, not counts.
