OVERVIEW
The ABS re-benchmarks Labour Force data once a quarter (ahead of the release of February, May, August and November issues) to ensure the estimates are based on the most up to date population benchmarks. This publication presents the estimates up to January 2018 based on the revised population benchmarks.
Revisions to original data resulting from rebenchmarking are usually confined to the previous 22 months. However, last quarter the ABS rebenchmarked 76 months of data: from July 2011 to June 2016 (the 60 months between the 2011 and 2016 Censuses) to accommodate the preliminary rebasing of population data to the 2016 Census; and thereafter from August 2016 to October 2017 (16 months) as is standard practice. In this issue the ABS has only rebenchmarked those months where population data has been revised, from July 2017 to January 2018 (7 months).
Incorporating the latest revised population benchmarks has resulted in minor revisions across the Labour Force series. Whilst the population benchmarks were only revised from July 2017 to January 2018, minor revisions to seasonally adjusted and trend estimates will also occur throughout the time series due to concurrent seasonal adjustment.
Detailed information on the extent of revisions resulting from rebenchmarking can be derived by comparing the data released in this issue and the data released in the January 2018 issue of Labour Force, Australia (cat. no. 6202.0) on 15 February 2018.
Further information on the process of rebenchmarking the period between the 2011 and 2016 Censuses, can be found in the article "Major Rebenchmarking of Labour Force Series" in the October 2017 issue of Labour Force, Australia - Rebenchmarked Estimates (cat. no. 6202.0.55.003).
The ABS will continue with the regular quarterly rebenchmarking, as per the process outlined in the article ‘Rebenchmarking of Labour Force Series’, published in the February 2015 issue of Labour Force, Australia (cat. no. 6202.0). However, as noted in the article "Refocusing 6202.0.55.003 towards major rebenchmarking", published in this release, this publication is being refocused from a quarterly release to a periodic release, used to communicate the outcomes of major bebenchmarking processes.
Users of this rebenchmarking product are encouraged to compare data with that included in the previous release of Labour Force, Australia (cat. no. 6202.0). However, these rebenchmarked estimates are produced for information only, and should not be considered a replacement for the estimates in Labour Force, Australia (cat. no. 6202.0).
