REVISION OF POPULATION BENCHMARKS
Labour Force Survey (LFS) estimates of persons employed, unemployed and not in the labour force are calculated to add up to independent estimates of the civilian population aged 15 and over, referred to as population benchmarks. For the LFS estimates these population benchmarks are based on Census of Population and Housing (Census) data, adjusted for under-enumeration and updated for births, deaths, interstate migration, and net permanent and long term migration. Revisions are made to population benchmarks after each five-yearly Census.
From the February 2009 issue of the Labour Force, Australia (cat. no. 6202.0) and subsequent associated Labour Force releases, LFS estimates will be compiled using population benchmarks based on results from the 2006 Census. Additionally, for the period June 2001 to January 2009, LFS estimates will be revised based on the 2006 population benchmarks. The revised estimates will also be available with the release of the February 2009 issue of this publication on 12 March 2009.
REVISION OF LABOUR FORCE SURVEY STATISTICAL REGIONS
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 will be produced based on the 2006 LFS Statistical Regions. Additionally, LFS estimates will be revised back to November 2007 based on the new regions. For further details, see Information Paper: Labour Force Survey Sample Design (cat. no. 6269.0).
CLASSIFICATION OF INDUSTRY AND OCCUPATION
From the February 2009 issue of Labour Force, Australia, Detailed, Quarterly (cat. no. 6291.0.55.003) the industry and occupation employment estimates will be based on new classification structures.
Industry will be classified to the Australian and New Zealand Standard Industrial Classification (ANZSIC) 2006. This classification system will replace 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).
Occupation will be classified to the Australian and New Zealand Standard Classification of Occupations (ANZSCO). This classification system will replace 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).
