QUALITY DECLARATION SUMMARY
Deaths data excludes:
Death records are provided electronically to the ABS by individual state/territory Registrars on a monthly basis for compilation into aggregate statistics on a quarterly and annual basis.
Quarterly estimates of deaths on a preliminary basis are released five to six months after the reference period in Australian Demographic Statistics (cat. no. 3101.0), and revised 21 months after the end of each financial year. Annual estimates on a year of registration basis are generally released within eleven months of the end of the reference year in Deaths, Australia (cat. no. 3302.0).
One dimension of timeliness in death registrations data is the interval between the occurrence and registration of a death. As a result, around 5% of deaths occurring in one year are not registered until the following year or later.
Information on deaths is obtained from a complete enumeration of deaths registered during a specified period and are not subject to sampling error. However, deaths data sources are subject to non-sampling error which can arise from inaccuracies in collecting, recording and processing the data.
Sources of non-sample error include:
Every effort is made to minimise error by working closely with data providers, the careful design of forms, training of processing staff, and efficient data processing procedures.
Although it is considered likely that the vast majority of deaths of Aboriginal and Torres Strait Islander Australians are registered, a proportion of these deaths are not registered as such. Information about the deceased is supplied by a relative or other person acquainted with the deceased, or by an official of the institution where the death occurred and may differ from the self-identified Indigenous origin of the deceased. Forms are often not subject to the same best practice design principles as statistical questionnaires, and respondent and/or interviewer understanding is rarely tested. Over-precise analysis of Aboriginal and Torres Strait Islander deaths and mortality should be avoided.
The international standards and recommendations for the definition and scope of deaths statistics in a vital statistics system are set out in the Principles and Recommendations for a Vital Statistics System Revision 2, released by the United Nations Statistical Division (UNSD). Consistent with the UNSD recommendations, the ABS defines a death as the permanent disappearance of all evidence of life at any time after live birth has taken place. In addition, the UNSD recommends that the deaths to be counted include all deaths "occurring in every geographic area and in every population group comprising the national area". For the purposes of Australia, this includes all deaths occurring within Australia as defined by the Australian Standard Geographical Classification (ASGC), July 2011 (cat. no. 1216.0) or Australian Statistical Geography Standard (ASGS): Volume 1 - Main Structure and Greater Capital City Statistical Areas, July 2011 (cat. no. 1270.0.55.001) that applies at the time.
Registration of deaths is compulsory in Australia under relevant state/territory legislation. However, each state/territory Registrar has its own death registration form. Most data items are collected in all states and territories and therefore statistics at a national level are available for most characteristics. In some cases, different wording of questions asked on the registration form may result in different answers, which may affect final figures.
Use of the supporting documentation released with the statistics is important for assessing coherence within the dataset and when comparing the statistics with data from other sources. Changing processes over time and/or across data sources can affect consistency and hence interpretability of statistical output. The Explanatory Notes in each issue contains information pertinent to that particular release which may impact on comparison over time.
Data presented in this release are reported by year of registration (unless otherwise stated) and differ from deaths statistics released in Australian Demographic Statistics (cat. no. 3101.0) which are reported on a year/quarter of occurrence basis in revised and final data for use in population estimates.
Statistics relating to cause of death are released annually by the ABS in Causes of Death, Australia (cat. no. 3303.0).
Deaths statistics are generally straightforward and easy to interpret. It should be noted, however, that changes in numbers of deaths over time can be due to a number of factors including changes in mortality and changes in the size and age/sex structure of the population. For this reason, deaths data needs to be considered in relation to the size of the relevant population(s) through the use of mortality rates.
Information of mortality rates, as well as data sources, terminology, classifications and other technical aspects associated with the statistics presented in this release can be found in the Explanatory Notes, Appendices (Characteristics available and Features articles list) and Glossary.
Deaths data is available in a variety of formats on the ABS website under the 3302.0 product family.
The formats are:
Further information on deaths and mortality may be available on request. See Appendix: Characteristics Available for a list of data items available. The ABS observes strict confidentiality protocols as required by the Census and Statistics Act (1905). This may restrict access to data at a very detailed level which is sought by some users.
