The ABS has identified a processing error with the New South Wales birth registrations data for the September 2011 and earlier quarters. The data for the September quarter 2011 have been corrected in this issue. For further details, see paragraph 12 of the Explanatory Notes.


Population data for the recent intercensal period (September quarter 2006 to June quarter 2011) have been updated using information from the 2011 Census of Population and Housing (2011 Census). Preliminary rebased Estimated Resident Population (ERP) data for September quarter 2006 onwards in this publication are now based on the 2011 Census, unless footnoted otherwise.

The preliminary rebasing has caused Australia's population estimate for June quarter 2011 to be revised down by 294,400 with similar-sized revisions for subsequent quarters. A significant component of this revision was due to improvements in the ABS Post Enumeration Survey. This revision has also affected estimates of population growth between 2006 and 2011. See the Technical Note on page 66 and the Feature Article on page 17 for further information.


This publication contains final, revised and preliminary data based on a process of scheduled revisions. For the current status refer to the table Status of quarterly ERP data at paragraph 7 of the Explanatory Notes.

Preliminary rebased population estimates for sub-state areas including Local Government Areas will be released in Regional Population Growth, Australia, 2006-2011 (cat. no. 3218.0).


Tables with quarterly time series have been extended from September quarter 2006 in order to reflect changes related to the process of preliminary rebasing to the 2011 Census.

Demography News is now published as part of this release online.


Information Paper: Ensuring the Quality of Rebased Population Estimates, 2011 (cat. no. 3250.0) - scheduled for release 5 July 2012.
