ABOUT THIS ISSUE
This issue contains estimates of the resident population of areas of Australia for 30 June 2005 to 2015. Estimates are provided for Statistical Areas Level 2 to 4 (SA2s - SA4s), Greater Capital City Statistical Areas (GCCSAs), Significant Urban Areas (SUAs), Remoteness Areas (RAs), State Electoral Divisions (SEDs), and states and territories of Australia, according to the 2011 edition of the Australian Statistical Geography Standard (ASGS). Estimates are also provided for Commonwealth Electoral Divisions (CEDs) based on 2013 boundaries and Local Government Areas (LGAs) based on 2015 boundaries.
The summary commentary in this issue focuses on population changes at the SA2 level and above between 30 June 2014 and 30 June 2015. All estimates are available from the Downloads tab.
The total population of the Other Territories, namely Christmas Island, Cocos (Keeling) Islands and Jervis Bay, is included in all references to the total population of Australia. However, the Other Territories are excluded from commentary about the states and territories of Australia.
ERP STATUS AND FUTURE RELEASES
The estimates in this issue are final for 2005 to 2011, revised for 2012, 2013 and 2014 (denoted 2012r, 2013r and 2014r), and preliminary for 2015 (denoted 2015p). Estimates for 2013 in this issue are different to the previous 2013 estimates, due to a change in the state/territory revision cycle.
Age-sex breakdowns of these estimates will be released on 18 August 2016 in Population by Age and Sex, Regions of Australia, 2015 (cat. no. 3235.0).
ACCURACY OF POPULATION ESTIMATES
It is important to recognise that sub-state/territory population estimates in this product are produced using Census data, mathematical modelling and population-weighted geographical correspondences and are subject to some error. A degree of caution should be exercised when using the estimates, especially for areas with very small populations. For more information see paragraphs 12 to 15 of the Explanatory Notes.
All statistics included in the commentary for this publication have been presented as rounded values. While unrounded figures are provided in spreadsheets, accuracy to the last digit should not be assumed.
CHANGES IN THIS ISSUE
This issue contains a Feature Article that examines changes in ERP for selected mining regions in Australia from 2005 to 2015.
REGIONAL INTERNAL MIGRATION ESTIMATES
In 2015, the ABS released a new series of regional internal migration estimates (RIME) for regions including SA2s and LGAs for the period 2006-07 to 2013-14. Updated data for 2014-15 has now been released on the ABS website in Migration, Australia (cat. no. 3412.0). Revisions to the 2006-07 to 2013-14 estimates have also been made in this release, due to enhancements to the methodology used to prepare the series. The RIME series is not directly comparable with ERP because of the different methods and source data used to prepare each series.
