Population

Understanding South Australia's growing, changing population


The population of South Australia continues to grow and its composition is changing. The state government prepares population projections every five years, following the release of the Census of Population and Housing published by the Australian Bureau of Statistics (ABS).

Population projections help us to understand the most likely future size, age structure and distribution of the population of the state. These projections are fundamental to urban, transport and infrastructure planning.

For more information about population projections email DPTI.PDPlanningInformation@sa.gov.au.



Our future population

The state government provides population projections at several geographic levels which are updated every five years. These projections follow the release of final figures from the most recent Census of Population and Housing published by the Australian Bureau of Statistics (ABS).
