Understanding AEDC community boundaries
AEDC geographic boundaries are defined for the whole country to ensure that the data is reported in the most useful way possible, but still align with commonly understood geography, such as suburbs. Those boundaries enable AEDC results to be reported at four different geographic levels: Local Community, Community, State/Territory and National.

To enable trend analysis over all three cycles and allow accurate comparison of AEDC and socio-demographic data from the Australian Bureau of Statistics (ABS), the AEDC geography was updated in order to match the new Australian Statistical Geography Standard (ASGS) released by the ABS in 2011. Revised boundaries were used for the 2015 collection and applied retrospectively to the 2009 and 2012 collections.
