Small Area Labour Markets – Explanatory Notes
State/Territory data by Statistical Area Level 2
Local Government Area
(LGA) are presented in Tables 1 and 2, respectively, in the downloadable PDF, and in separate downloadable xlsx/csv files, both on the
SALM Estimates page.
For the States and the Northern Territory, estimates for the Capital City and the Rest of State area are also presented in Table 1 of the PDF.
There are around 2,300 SA2s and 540 LGAs in Australia. The SA2s are a geographical unit that are contained within the Statistical Area Level 4s in the Australian Bureau of Statistics’ (ABS) 2016 Australian Statistical Geography Standard (ASGS), upon which the ABS Labour Force Survey data are based. The SA2 estimates are then apportioned to the LGA level using population weights based on the latest available SA2 to LGA correspondence from the ABS.
The SA2 estimates are based on the Structure Preserving Estimation (SPREE) methodology, which allows the generation of small area unemployment, unemployment rate and labour force estimates. Given the level of disaggregation involved, the data are smoothed (i.e. averaged) over four quarters to reduce the variability, characteristic in the small area estimates.
The SA2 (and, once apportioned, the LGA) estimates are derived from three primary data sources:
• Current recipients of Youth Allowance (other), and current recipients of Newstart Allowance/JobSeeker Payment who are not on a zero rate of payment, by SA2.
• ABS Labour Force Survey data by ABS Statistical Area Level 4 (SA4). The ABS Labour Force Survey samples private and non-private dwellings (approximately 6,000 households) across Australia and covers about 0.32% of the population. More details about the methodology underpinning this survey are included in the ABS publication, Labour Force, Australia.
• Participation rate data at the SA2 level from the Census of Population and Housing (the latest SALM data use the 2016 Census, but estimates prior to the March quarter 2014 use 2011 Census benchmarks).
Unemployment estimates are produced by apportioning the level of unemployment at the SA4 level, as published by the ABS, across each of the SA2s within that region. This apportioning is based on the distribution of Centrelink Newstart/JobSeeker and Youth Allowance (other) beneficiaries at the SA2 level, benchmarked by ABS unemployment estimates by age, sex and marital status at the Greater Capital City Statistical Area (GCCSA) level.
Labour force estimates are produced by:
• taking the participation rate for each SA2 from the Census (in instances where an SA2 does not have a participation rate, the participation rate for the SA3 is used as a proxy),
• applying this to the latest available ABS estimated resident population (ERP) data for persons aged 15 and over for the SA2, to produce a labour force weighting for the SA2 within the SA4, and then
• allocating the total labour force for each ABS SA4 to the SA2s within that region according to the labour force weighting.
By using Census participation rates and the latest available ERP, the SA2 labour force estimates can adjust to changes in the distribution of population within an SA4 that have occurred since the last Census.
Unemployment rate estimates are produced by calculating the level of unemployment as a proportion of the labour force (consistent with ABS methodology).
As the reliability of estimates at the SA2 level are related to the size of the SA2, estimates are only published for SA2s that have a labour force of 100 or more as at the June quarter 2020. In addition, higher levels of caution should still be exercised when interpreting movements in the estimates for SA2s or LGAs with a labour force of less than 1,000.
While the underlying methodology used to produce the small area estimates in SALM is robust for the vast majority of areas, in a small number of cases it can result in figures that do not accurately reflect labour market conditions within the region. As this is the case for the SA2 and LGA of Aurukun, these figures are not published.
Due to both the methodology used and the significantly higher variability of the data disaggregated below the SA2 or LGA level, it is not possible to derive reliable unemployment and unemployment rate estimates for particular groups (e.g. males, females, youth) within an SA2 or LGA.
Derivation of Employment Estimates
The SA2 and LGA data in this publication are synthetic estimates based on ABS and Centrelink unemployment numbers and labour force data from the Labour Force Survey and the Census. As the production of SALM does not involve the use of any sources of, or attempt to estimate, the level of employment in an SA2, employment estimates should not be derived from these statistics. For more information, please email SALM@skillscommission.gov.au.
The smoothed SA2 and LGA estimates are the National Skills Commission’s official estimates of unemployment and the unemployment rate at those levels. It is recognised, however, that some advanced users may need access to the unsmoothed estimates, which are used to produce the official figures, and these are provided below. We recommend using extreme caution when interpreting quarter-to-quarter (or even year-to-year) changes in the unsmoothed series.

2011 ASGS SA2 and LGA Estimates
Due to the quarterly population rebenchmarking of regional ABS Labour Force Survey data, the more recent 2011 ASGS estimates (up to the March quarter 2019) will continue to be revised for a number of quarters going forward. Estimates for those SA2s that have not had a break in series are included in the data files available online. However, if users need to obtain the latest available 2011 ASGS SA2 or LGA estimates for areas that have had a break in series, please email SALM@skillscommission.gov.au.
