MAIN STRUCTURE OF THE AUSTRALIAN STANDARD GEOGRAPHICAL CLASSIFICATION (ASGC)

PURPOSE

The Main Structure of the ASGC is used to collect and disseminate a broad range of ABS social, demographic and economic statistics Although the Main Structure is the most widely used and has broad application, the other structures are equally important to their own purposes

THE STRUCTURE

The Main Structure has five hierarchical levels at Population Census times, comprising in ascending order: CDs-SLAs-SSDs-SDs-S/Ts In non-census years, CDs are undefined and the Main Structure thus has only four levels of hierarchy

In this structure, CDs aggregate to form SLAs, SLAs aggregate to form SSDs and this aggregation principle continues up the remaining hierarchical levels At each hierarchical level, the component spatial units (e.g SLAs) collectively cover all of Australia without gaps or overlaps
