ABOUT THIS PUBLICATION
This release brings together statistics on international migration into and out of Australia, internal migration within Australia (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 paragraph 9 of the Explanatory Notes.
In this release, 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 release is based on unrounded data. Calculations based on rounded data may differ to those published.
REBUILD OF THE OVERSEAS ARRIVALS AND DEPARTURES SYSTEM (ROADS)
The ABS undertook a rebuild of the Overseas Arrivals and Departures (OAD) system in 2013. The primary aim was to improve the quality of OAD data, given its importance as input to a broad range of estimates, including the estimation of Net Overseas Migration and the Estimated Resident Population by country of birth, which are both featured within this release. Detailed information in the changes and improvements arising from the rebuild of the OAD system appears in the Data Quality Issues (Appendix) in the Explanatory Notes section of Overseas Arrivals and Departures (cat. no. 3401.0).
