Population: Australian population

Australian population

National state and territory population published by the Australian Bureau of Statistics (ABS) contains the latest, quarterly estimated residential population (ERP) nationally and by state and territory. Data presented is based on the results of 2016 Census of Population and Housing.

ERPs are based on Census counts by place of usual residence (excluding short-term overseas visitors), to which the estimated Census net undercount and the number of Australian residents estimated to have been temporarily overseas on Census night are added. Estimates are revised annually in June and are finalised following Census. Estimates post-Census are obtained by adding natural increase and net overseas migration to the ERP at the beginning of each period.

National state and territory population data are also used in the following dashboard menu options: Australian population - age and sex and Australian population projections.
