Time series estimates of payroll jobs by sub-state regions, Statistical Area 4 (SA4) and Statistical Area 3 (SA3), are presented as index values through to the week ending 2 January 2021 in Table 5 of the Data downloads.
SA4 regions are specifically designed to reflect labour markets within each state and territory within population limits. In regional areas, SA4s tend to have lower populations (100,000 to 300,000), while in metropolitan areas, SA4s tend to have larger populations (300,000 to 500,000).
SA3 regions generally have populations between 30,000 and 130,000 persons. They are often the functional areas of regional towns and cities with a population in excess of 20,000, or clusters of related suburbs around urban commercial and transport hubs within the major urban areas.
