General Practitioner Catchment (GPC)

Developed by the Australian Government Department of Health and Aged Care as custom aggregations of the Australian Bureau of Statistics (ABS) Australian Statistical Geography Standard (ASGS) 2021 Statistical Area Level 1 (SA1), Statistical Area Level 2 (SA2), Statistical Area Level 3 (SA3), and Urban Centre and Locality (UCL) geographies. The GP catchment areas give a more accurate picture of where patients access their health services.

Statistical Area Level 2 (SA2)

SA2s are geographic units used in the Australian Statistical Geography Standard (ASGS). Built from SA1s, they are designed to represent communities with shared social and economic interactions. There are 2,473 SA2s across Australia, including special codes for populations without fixed locations. SA2s are commonly used for publishing non-Census ABS statistics such as health and population estimates, and they form the basis for SA3s and other regional structures like Significant Urban Areas and Tourism Regions.
