Changes to preliminary and revision timetables
Six-monthly revision cycle for NOM
The quarterly fluctuations experienced in Australia's population growth and thereby ERP are currently driven by NOM. To help reduce the impact of possible large revisions to population estimates from only revising NOM estimates once a year, as was the previous practice, the ABS has consulted with major stakeholders and has changed the current annual revision cycle for publishing final NOM to a six-monthly revision cycle. Table 4.4 shows the schedule of release for NOM estimates for the September quarter 2008 to June quarter 2012.
With the implementation of the new six-monthly revision cycle for NOM it also means the annual revision for natural increase can be released six months earlier (reverting to the previous practice) to be published in the March quarter issue released in September each year of Australian Demographic Statistics (cat. no. 3101.0) (see Table 4.4).
The improved methods for estimating preliminary NOM based on the 'one year ago' propensity model were published for the first time in ABS population estimates on 25 March 2010 in Australian Demographic Statistics, September Quarter 2009 (cat. no. 3101.0).
The improved preliminary NOM methods were applied to estimates from September quarter 2008 onwards. For September quarter 2008 to June quarter 2009, the already published preliminary NOM estimates based on the previous methods using a 'two year ago' propensity model were replaced with the improved preliminary NOM estimates. September quarter 2009 preliminary NOM estimates were based on the improved methods and published for the first time.
As part of the previous scheduled annual revision cycle, the September 2009 issue of Australian Demographic Statistics (cat. no. 3101.0) released on the 25 March 2010 also provided revised estimates for the 2007-08 financial year for births, deaths, natural increase, NOM and ERP.
