Statistical Areas Level 4 (SA4)
Statistical Areas 4 (SA4) are geographical areas that are made up of neighbouring Statistical Areas Level 3 (SA3s).
SA4s generally have a population of between 100,000 and 500,000. In regional areas, SA4s tend to have populations closer to the minimum (100,000 - 300,000). In metropolitan areas, the SA4s tend to have larger populations (300,000 - 500,000). There are 107 SA4 regions covering the whole of Australia without gaps or overlaps.
SA4s are named according to the areas they represent:
where a SA4 represents a labour market of a major city it is named after that city (e.g., Bendigo)
where a SA4 represents an employment centre within a larger city it is generally named to reflect both the larger city and the employment centre or part of the city that it represents (e.g., Melbourne - Inner South; Sydney – Blacktown)
where a SA4 represents a collection of labour markets in regional areas it is named using either a description of that part of the State and Territory or after one or more well-known regional areas that it closely replicates (e.g., Latrobe – Gippsland)
where this name does not identify it within Australia, it is generally preceded by the State and Territory name (e.g., Western Australia - Wheat Belt; Queensland – Outback)
The Other Territories of Jervis Bay, Cocos (Keeling) Islands, Christmas Island and Norfolk Island are together represented by a single SA4 in the 2016 ASGS.
