Data from the monthly Labour Force Survey are released in two stages. The Labour Force, Australia, Detailed - Electronic Delivery (cat. no. 6291.0.55.001) and Labour Force, Australia, Detailed, Quarterly (cat. no. 6291.0.55.003) are part of the second release, and include detailed data not contained in the Labour Force, Australia (cat. no. 6202.0) product set, which is released one week earlier.
The Labour Force, Australia, Detailed - Electronic Delivery (cat. no. 6291.0.55.001) is released monthly. Labour Force, Australia, Detailed, Quarterly (cat. no. 6291.0.55.003) includes data only collected in February, May, August and November (including industry and occupation).
Since these products are based on the same data as the Labour Force, Australia (cat. no. 6202.0) publication, the 6202.0 Labour Force, Australia Explanatory Notes are relevant to both releases.
REBENCHMARKING OF AGGREGATE HOURS WORKED SERIES
The annual rebenchmarking of the aggregate hours worked series was conducted in July. This has resulted in some minor historical revisions to the aggregate hours worked data. For further detail on the methodology see Information Paper: Expansion of Hours Worked Estimates from the Labour Force Survey, Australia, 2009 (ABS cat. no. 6290.0.55.001).
PHASE-IN OF NEW LABOUR FORCE SAMPLE
Phase-in of a new sample design, as well as expanding the roll out of the offer of online self completion of the Labour Force Survey, commenced in May 2013 and have continued in July.
The phase-in of a new survey sample has resulted in a short term increase in the standard errors associated with Labour Force data. Standard errors on month-to-month movement estimates are predicted to increase by approximately 10% during this period but will only have a marginal impact on the quality of level estimates. For further details, refer to the article on page 10 of the May 2013 issue of this publication and the Information Paper: Labour Force Survey Sample Design, May 2013 (ABS cat. no. 6269.0).
The simultaneous introduction of two rotation groups per month between May and August 2013 has resulted in a lower proportion of the sample matched between months. In July 2013, the new sample for more remote, less populated areas and non-private dwellings was also introduced for New South Wales, Victoria, Queensland, South Australia and Western Australia.
STANDARD ERROR MODEL
The model underlying standard errors associated with labour force data has been updated to reflect that the labour force sample is now based more than 50 per cent on the 2011 sample. Updated standard errors are published in the Standard Errors section of this issue, and in the Labour Force Standard Errors, Data Cube, May 2013 (ABS cat. no. 6298.0.55.001).
