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.
ANNUAL SEASONAL REANALYSIS
The annual seasonal reanalysis of the Labour Force series was conducted on estimates up to January 2014. The seasonally adjusted and trend estimates in this issue reflect adjustments made to the data as a result of this reanalysis. An exception is the aggregate hours worked series on which the annual reanalysis was conducted on estimates up to December 2013 and applied from January 2014, as noted in last month's issue.
While seasonal factors for the complete time series are estimated each month, they are reviewed annually at a more detailed level than is possible in the monthly processing cycle. The annual seasonal reanalysis takes into account each additional year's original data and assesses the appropriateness of seasonal adjustment parameters. An annual seasonal reanalysis does not normally result in significant changes to published estimates. Refer to the article on Annual Seasonal Reanalysis on page 6 of February issue Labour Force, Australia (cat. no. 6202.0) publication for more details.
CHANGES TO DATACUBES
The SuperTABLE datacubes released this month have had minor superficial changes to their titles, filenames and internal database ids. This is to better reflect the contents of the datacubes due to last months changes that were made as part of the 20 year rebenchmarking excercise and the change in geography to the Australian Statistical Geography Standard (ASGS). The typical three character naming convention has also been applied consistently to both the filename and internal database id. Redundant meta-information and RSE annotation cut-offs have also been removed from the datacubes. Comprehensive RSE cut-off values are provided in the Explanatory Notes
The data field names, recodes, and table structures inside the datacubes have remained unchanged in order to minimise any disruptions to user created templates and other automatic extraction tools.
This month, the RM1 datacube has been modified since the first version released last month. Previously, sub-totals and totals had been pre-calculated and included as items in the datacube, which would cause incorrect "double-counting" of estimates if data fields were removed from the table. This month, the sub-totals and totals are included as recodes built from the base level, so removing fields will no longer have any impact on the resulting estimates.
However, datacubes RM2 and RM3 still include pre-calculated sub-totals and totals. This is due to the 'median duration of job search' item which can't be aggregated from the base level. A series of recodes have been included to help users redefine the table structure without producing incorrect estimates, but care must be taken to keep all fields present in the table.
