Statistical Area Level 2 (SA2) Overview
SA2s have been designed as a replacement for Statistical Local Areas (SLAs), though 2011 Census data will still be made available for SLAs in 2012. They are built from whole SA1s and aim to roughly represent a population of between 3,000 and 25,000 persons.
SA2 vs. SLA
Example: Geelong, VIC
- 12 x Statistical Local Area (SLA) in 2006
- 20 x Statistical Area Level 2 (SA2) in 2011
Designed to represent suburbs and localities
Aim: average 10,000 persons (2,000 min, 25,000 max)
Expected growth and major developments included in design
Much better granularity in populated areas
2,214 SA2s versus 1,426 SLAs
Mesh Blocks now fit cleanly within SA1s with no overlaps.
Unlike 2006, where MBs were an experimental geography and had no relationship to any other geography
- Will not aggregate to LGAs like in 2006
- Potentially less granularity for some remote areas
