INTRODUCTION
Estimated resident population (ERP) data in this publication are based on the 2001 Census of Population and Housing.
ERP DATA STATUS
At any point in time this publication contains final, revised and preliminary ERP data. The status of the ERP data included in this issue is as follows:
- Final - All ERP data up to and including June quarter 2001;
- Revised - ERP data from September quarter 2001 to June quarter 2005, inclusive;
- Preliminary - ERP data from September quarter 2005 to September quarter 2006, inclusive.
CHANGES IN THIS ISSUE
Changes included in this issue are as follows:

2006 CENSUS OF POPULATION AND HOUSING
The next issue of this publication will contain preliminary ERP for Australia, states and territories based on the results of the 2006 Census of Population and Housing. Previously published ERP from September quarter 2001 onwards will be revised to take account of a new census based population estimate. Final intercensal ERP will be released in the December quarter 2007 issue of this publication.
Improved method for estimating net overseas migration (NOM)
The ABS has developed an improved method for estimating NOM. Preliminary estimates for September and December quarters 2006 based on the new method will be available in the next issue of this publication. The key change is the introduction of a '12/16 month rule' for measuring a person's residency in Australia, replacing the current '12/12 month rule'. For further information see Information Paper: Improved Methods for Estimating Net Overseas Migration (cat. no. 3107.0.55.003) released on 10 February 2006, and Information Paper: Statistical Implications of Improved Methods for Estimating Net Overseas Migration, Australia 2006 (cat. no. 3107.0.55.005) to be released on 26 April 2007.
DATA NOT YET AVAILABLE
A new methodology has been proposed for annual household estimates and is currently being assessed. In the interim, tables 17, 18 and 19 have been replaced with household projections (now tables 17 and 18).
