Comments
Statistical Areas Level 1 (SA1s) are designed to maximise the spatial detail available for Census data. Most SA1s have a population of between 200 to 800 persons with an average population of approximately 400 persons. This is to optimise the balance between spatial detail and the ability to cross classify Census variables without the resulting counts becoming too small for use.
SA1s aim to separate out areas with different geographic characteristics within Suburb and Locality boundaries. In rural areas they often combine related Locality boundaries.
SA1s are aggregations of Mesh Blocks.
SA1s are identified by an 11-digit fully hierarchical code. The SA1 identifier is a 2-digit code, assigned within an SA2.
