ESTIMATED RESIDENT POPULATION RELEASE CHANGES
Six-monthly revisions to Estimated Resident Population
Estimated Resident Population (ERP) revisions will occur six-monthly from September 2010 onwards with the release of Australian Demographic Statistics for March quarter 2010 (cat. no. 3101.0). These improvements are designed to give a more up-to-date and accurate ERP by using more up-to-date Net Overseas Migration (NOM) data.
As outlined in Information Paper: Improving Net Overseas Migration Estimation, Mar 2010 (cat. no. 3412.0.55.001), in consultation with major stakeholders, ABS will change the current annual revision cycle for publishing final NOM to a six-monthly revision cycle. While this will not have any impact on the difference between preliminary and final NOM estimates, this change will provide for the earlier release of revised ERP figures.
Merging of age-sex population estimates into Australian Demographic Statistics (cat. no. 3101.0)
From March quarter 2010 (scheduled for release in September 2010), Australian Demographic Statistics (cat. no. 3101.0) will include ERP broken down by age and sex, and other associated data which has previously been published in Population by Age and Sex, Australian States and Territories (cat. no. 3201.0). The inclusion of age-sex data in this publication will ensure consistency between ERP totals and the relevant age-sex breakdown at all times, particularly following ERP revisions. The production of Population by Age and Sex, Australian States and Territories (cat. no. 3201.0) will cease following the release of June quarter 2010 data (scheduled for release in December 2010).
