ABOUT THIS PUBLICATION
This publication brings together statistics on international migration into and out of Australia, internal migration within Australia (including interstate and intrastate) and information on overseas-born residents of Australia.
STATUS OF DATA WITHIN THIS PUBLICATION
The status of estimated resident population (ERP) by country of birth, and the components of population change (natural increase, net interstate migration (NIM) and net overseas migration (NOM)), are referred to as either preliminary, revised or final. For further information see paragraphs 9–10 of the Explanatory Notes.
In this publication, figures have sometimes been rounded. Rounded figures and unrounded figures should not be assumed to be accurate to the last digit shown. Where figures have been rounded, discrepancies may occur between the sums of component items and totals. Analysis featured in this publication is based on unrounded data. Calculations made on rounded data may differ to those published.
NET OVERSEAS MIGRATION
In 2007, the Australian Bureau of Statistics (ABS) introduced improved methods known as the '12/16 month rule', for calculating net overseas migration (NOM). These methods have 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. In 2009, the methodology used for preliminary NOM estimation was further improved. For additional information see the Explanatory Notes 35-37.
A time series of final NOM from 2004 onwards, based on the '12/16 month rule' is available electronically as a data cube from the Downloads tab of this publication on the ABS website.
