Estimated Resident Population
About this topic
Estimated Resident Population (ERP) is the Australian Bureau of Statistics' official measure of the usually resident population for an area. It updates Census counts using births, deaths and migration, so it is the preferred time-series population measure for annual trend analysis.
This page shows annual total ERP for persons in the selected local government area only. Benchmark lines, suburb views and sex splits are intentionally out of scope for this first release.
