NET OVERSEAS MIGRATION
In 2007, the Australian Bureau of Statistics (ABS) introduced improved methods 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, changes to the Federal Financial Relations Act 2009 allowed the ABS to publish quarterly Estimated Resident Population (ERP) at the end of each scheduled month of release (March, June, September and December). These changes enabled the methodology used for preliminary NOM estimation to be improved. For further information, see Chapter 4 - Improving net overseas migration estimation - Recent changes.
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.
Housing Mobility in Australia explores aspects of mobility for people who have responded to the Survey of Income and Housing, 2007-08. It examines characteristics including frequency of moves, reasons for moving, mobility by age and sex, income and educational attainment.
