STATUS OF DATA WITHIN THIS PUBLICATION Estimated resident population (ERP) by country of birth and interstate migration estimates are final for years up to and including 2005–06, revised for 2006–07 and preliminary for 2007–08. Overseas migration estimates are final for years up to and including 2006–07 and preliminary for 2007–08. See paragraphs 9–10 of the Explanatory Notes for further information. NET OVERSEAS MIGRATION In 2007 the Australian Bureau of Statistics (ABS) introduced improved methods for calculating net overseas migration (NOM). It has been used in calculating Australia's official estimated resident population (ERP) since September quarter 2006. As a result a break in the NOM time series exists from the 2006–07 financial year. Caution should be taken when comparing estimates over time. For further information see paragraphs 22 to 32 of the Explanatory Notes and the Technical Note - Improved Methods for Calculating Net Overseas Migration from September quarter 2006 and onwards available soon under the Explanatory Notes tab with the electronic release of this publication. A time series based on this improved methodology from 2004 onwards is available electronically as a data cube (in Supertable format) from the Downloads tab of this publication on the ABS website. CHANGES IN THIS ISSUE The annual release date of this publication has changed from the usual scheduled release of March to July due to the introduction of the improved methods of calculating NOM. Final NOM data is now available 6 months later, 21 months after the end of the financial year instead of 15 months after. The content of this publication has been reviewed. Tables previously in the printed publication (PDF format) have been removed and are now available electronically as data cubes (in Supertable or Excel format) from this publication on the ABS website. The time series data cube Permanent arrivals, Country of birth is no longer available under this catalogue number but will be available in future in Australian Historical Population Statistics (cat.no.3105.0.65.001). Data on the state and territory composition of Australia's ERP by country of birth are only available for census years. Updated data based on the 2006 Census are now available electronically as a data cube (in Excel format) under the Downloads tab of this publication on the ABS website.
