What are SA1s, SA2s and SA3s?
When viewing datasets on the map you can see the data displayed at three different levels SA3, SA2, SA1. SA1 is the most granular of these and is the area upon which all calculations in Community Insight Australia are built.
SA1s have a population of between 200 and 800, with an average of around 400 people. Most of the data generated from the ABS Census is available at SA1 level. SA1s are referred to by number only. Their numbers are extensions of SA2 numbers.
SA2s are similar in size to suburbs, and are called by suburb names. This is the smallest granularity Centrelink data is available.
SA3s are regions. Most of our health data has a granularity of SA3. |
