Regional population by age and sex, 2024

All population estimates are as at 30 June 2024.

The median age is the age at which half the population is older and half is younger.

The sex ratio is the number of males per 100 females.

Any reference to capital city refers to Greater Capital City Statistical Area (GCCSA), and any reference to area refers to Statistical Area Level 2 (SA2).

Capital cities

People aged 20 to 44 years made up 38% of the combined capital city population, compared with 30% of the population in the rest of Australia.
People aged 55 years and over made up a smaller proportion of the population in capital cities (26%) than in the rest of Australia (34%).
The sex ratio in the combined capital cities was 98.4 males per 100 females, compared with 99.0 for the rest of Australia, indicating a higher share of females in the capitals.

Interactive maps

The following maps display the proportion of the population aged 0 to 14 years, 15 to 64 years, and 65 years and over for SA2s. Additional data, including median age and sex ratio, can be viewed by clicking on a region of interest.

All SA2 maps, and similar maps for Local Government Areas (LGAs), are also available at Regional population by age and sex 2024: Age distribution.

Population aged 0 to 14 years, SA2s

This interactive map displays the proportion of the population aged 0 to 14 years for SA2s as at 30 June 2024. The population is divided into six data classes:

22.0% or more (dark red)
20.0% to less than 22.0% (light red)
18.0% to less than 20.0% (dark orange)
16.0% to less than 18.0% (light orange)
Less than 16.0% (yellow)
No population (grey).

The map shows that the SA2s with the highest proportions of population aged 0 to 14 years were largely in the outer suburbs of capital cities or regional areas including:

Northern Peninsula (33.2%) and Palm Island (32.1%) in northern Queensland, which both had a high proportion of Aboriginal and/or Torres Strait Islander people
Tarneit (West) - Mount Cottrell (32.5%), Cobblebank - Strathtulloh (32.4%) and Tarneit - North (32.1%), all in Melbourne’s outer west.

The areas with the lowest proportions in this age group were:

Acton (1.8%) in Canberra, which contained the Australian National University
inner-city Melbourne CBD - North (2.1%), Melbourne CBD - West (2.6%) and Melbourne CBD - East (3.0%)
Chippendale in inner Sydney (2.8%).
