POPULATION BENCHMARKS

The Labour Force Survey estimates are calculated in such a way as to add up to the estimate of the civilian population aged 15 years and over (population benchmarks). These are based on the Estimated Resident Population (ERP) series published in Australian Demographic Statistics (cat. no. 3101.0).

For this release of the Longitudinal Labour Force Survey (LLFS) CURF, the population benchmarks are based on the March 2012 edition of ERP. In this edition, the data up to and including December 2010 is based on 'final' estimations of Net Overseas Migration (NOM), Net Interstate Migration (NIM) and natural increase (difference between the number of births and the number of deaths). These estimates of quarterly population growth have been applied to the current 2006 Census population base in order to produce monthly population benchmarks for the period January 2008 to December 2010 for sex by age by state/territory by area of usual residence (see Population count [POPCNTC]).

The LLFS CURF benchmarks used in this release match the benchmarks published in the November 2012 release of the main Labour Force, Australia publications (cat. no. 6202.0, cat. no. 6291.0.55.001 and cat. no. 6291.0.55.003), so the cross-sectional ('point-in-time') estimates tabulated from the CURF will closely match the published original estimates.

Tabulations based on data items from the supplementary surveys will not match the officially published estimates in those related publications, as these are be based on different benchmarks, estimation methods, and population exclusions.

Every five years, the ERP series are revised to incorporate additional information available from the latest Census of Population and Housing (Census). Information from the 2011 Census has yet to be incorporated into the ERP series - these revisions are due for release on 20 June 2013. Following the release 2011 Census based ERP, the Labour Force benchmarks will also be revised to match the new series and are likely to be applied in early 2014 to the main Labour Force, Australia publications. When this happens, the population benchmarks used in this release of the LLFS CURF will not align with the most current ERP therefore the LLFS CURF may be subject to revisions in a future release of the CURF.
