ABOUT THIS ISSUE
This release brings together statistics on deaths and mortality in Australia. Data refer to deaths registered during the calendar year shown, unless otherwise stated. State or territory relates to state or territory of usual residence, unless otherwise stated.
CHANGES IN THIS ISSUE
Revisions to data: This issue contains a revision to both the Estimated Resident Population (ERP) and resulting death rates for 2013. Data for 2013 now have the status of revised and will not change until ERP is rebased after the 2016 Census.
Randomisation: To protect confidentiality, the Australian Bureau of Statistics (ABS) has introduced a technique to randomly adjust cells with small values in Deaths, 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 this 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.
Statistical Area methodology review: The ABS is currently reviewing the methodology used to produce 2001 to 2010 deaths data at the Statistical Area Levels 2, 3 and 4 (SA2, SA3 and SA4). The review will better align deaths 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 deaths for 2011 to 2014 will not be affected.
Rates and life expectancies in data cubes 4 and 5 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.
2014 POPULATIONS USED IN THIS RELEASE
All ERPs for 30 June 2014 (preliminary) are based on the results of the 2011 Census and are the latest available ERPs at the specified level. As a consequence of using the latest available ERPs for 2014, state and territory totals in sub-state data cubes are slightly different from those in other data cubes. This does not affect deaths data. The ERPs used in this release are as follows:
- State, Territory and Australia level ERP (preliminary status), released in Australian Demographic Statistics, December Quarter, 2014 (cat. no. 3101.0) published on 25 June 2015.
- ERP by Country of Birth for Australia (preliminary status), released in Migration, Australia, 2013-14 (cat. no. 3412.0) published on 29 January 2015.
- Sub-State ERP (preliminary status), released in Population by Age and Sex, Regions of Australia, 2014 (cat. no. 3235.0) published on 18 August 2015.
Calculations as shown in the commentary sections of this release are based on unrounded figures. Calculations undertaken by data users using rounded figures may differ from those released. Where figures have been rounded in tables, discrepancies may occur between sums of component items and totals.
Every effort is made to minimise error by working closely with data providers, including supporting the careful design of forms, training of processing staff, and efficient data processing procedures.
The efforts of Registries of Births, Deaths and Marriages to improve the data quality, coverage and timeliness of death registration information, processes and systems are noted and valued by the ABS.
Where necessary, tables in this release have had small values suppressed or randomised to protect confidentiality. As a result, sums of components may not add exactly to totals. These very minor adjustments allow for a greater amount of data to be released, and do not affect the utility of the data.
