CHANGES THIS MONTH
Changes to civilian population benchmarks are not uniform across age groups. The largest change was to the 65 years and over age group, with an average absolute revision of 23,800 persons. Benchmarks for those aged 25 to 34 years were revised by an average absolute change of 19,100 persons; those aged 35 to 44 years were revised by an average absolute change of 17,600 persons; those aged 45 to 54 years were revised by an average absolute change of 12,100 persons.
Employed persons, in trend terms, have been revised by an average absolute change of 31,200 persons. The revision to the employed persons estimates, is larger than the revision to the civilian population, due to age compositional effects. The largest revision to employed persons estimate was an increase of 81,200 persons for the September 2006 estimate.
Unemployed persons, in trend terms, have been revised by an average absolute change of 2,000 persons.
The unemployment rate, in trend terms, has been revised by an average absolute change of 0.01 percentage points.
The participation rate has been revised by an average absolute change of 0.105 percentage points. This is due to the age composition effects referred to earlier.
The ABS has introduced several other changes to detailed original data at the unit record level. These changes include:
Additional to implementation of revised population benchmarks and classifications as detailed above, annual reanalysis of seasonal factors has been conducted on all seasonally adjusted LFS series.
LFS STATISTICAL REGION BOUNDARIES
LFS Statistical Region boundaries are revised at each sample redesign to align with the Australian Standard Geographical Classification (ASGC) (cat.no.1216.0). From the February 2009 issues of Labour Force, Australia, Detailed- Electronic Delivery (cat.no.6291.0.55.001) and Labour Force, Australia, Detailed, Quarterly (cat.no.6291.0.55.003), regional estimates are produced based on the 2006 LFS Statistical Regions. Additionally, LFS estimates are revised back to November 2007 based on these new regions. For further details, see Information Paper: Regional Labour Force Statistics (cat.no.6262.0).
INDUSTRY AND OCCUPATION CLASSIFICATIONS
From the February 2009 issue of Labour Force, Australia, Detailed, Quarterly (cat.no.6291.0.55.003) the industry and occupation employment estimates are based on new classification structures: Industry is classified to the Australian and New Zealand Standard Industrial Classification (ANZSIC) 2006; Occupation is classified to the Australian and New Zealand Standard Classification of Occupations (ANZSCO).
The ANZSIC 2006 classification system replaces the existing classification ANZSIC 1993, for the periods November 1984 to the current release. Industry data will continue to be collected in the LFS to the Group (3 digit) level. For more information on the implementation of ANZSIC 2006 see Information Paper: Update on ANZSIC 2008 Implementation, 2006 (cat.no.1295.0.55.001).
The ANZSCO classification system replaces the classification Australian Standard Classification of Occupations (ASCO) Second Edition, introduced in August 1996. Occupation data will continue to be collected in the LFS to the Unit Group (4 digit) level. For more information on the implementation of ANZSCO see Information Paper: ANZSCO - Australian and New Zealand Standard Classification of Occupations, 2005 (cat.no.1221.0).
ANNUAL SEASONAL REANALYSIS
As a result of the revisions outlined above a reanalysis has been conducted on all seasonally adjusted LFS series. This reanalysis examines series for trend breaks, seasonal breaks, and outliers, and in this instance coincides with the annual reanalysis conducted for February issue each year.

On the ABS website, from this issue the corresponding time series spreadsheets Labour Force, Australia, Spreadsheets (cat.no.6202.0.55.001) will be included in Labour Force, Australia (cat. no. 6202.0).
