This publication brings together statistics for live births and fertility in Australia. Data refer to births registered during the calendar year shown, unless otherwise stated. State or territory relates to the state or territory of usual residence, unless otherwise stated.
This issue contains a revision to the Estimated Resident Population (ERP) and resulting birth rates for 2013. Data for 2013 now have the status of revised and will not change until ERP is rebased after the 2016 Census.
Parity (number of previous children of the mother) data for 2014 is not available for New South Wales due to data quality concerns. As national level parity data already excludes Victoria and Queensland, 2014 data for Australia is also not available. See Explanatory Note 51 for further information.
The ABS is currently reviewing the methodology used to produce 2001 to 2010 births data at the Statistical Area Levels 2, 3 and 4 (SA2, SA3 and SA4). The review will better align births data for 2001 to 2010 with that from 2011 onwards. Investigations by the ABS suggest that in most cases the changes to 2001 to 2010 data will be minimal. The results of this review are planned to be published by June 2016. The number of births for 2011 to 2014 will not be affected.
Rates and medians in data cubes 2 and 3 are calculated for each year and then averaged over the three-year period ending in the reference year. Due to this review, these data for 2011 and 2012 are not published in this issue.
To protect confidentiality, the Australian Bureau of Statistics (ABS) has introduced a technique to randomly adjust cells with small values in Births, Australia, 2014. This technique has been used for Causes of Death statistics since 2007 and allows the ABS to publish more data by removing the need to suppress cells. Cells with 0 values have not been affected by randomisation. The technique has been applied to 2014 registration based data only, and all years of occurrence based data. It has not been applied to the median age calculations or any sub-state data. Previously published data will not be republished using this randomisation method.
