Notes on the data: Aboriginal median age at death

Median age at death of Aboriginal people, 2013 to 2017

 

Policy context: The median age at death is an indicator of premature mortality. It is the age at which exactly half the deaths registered in a given time period were deaths of people above that age and half were deaths below that age. Over the five years 2013 to 2017, the median age at death of Aboriginal and Torres Strait Islander people for the combined jurisdictions of New South Wales, Queensland, South Australia, Western Australia and the Northern Territory was 56.0 years for males and 61.0 years for females [1]. The range in median age for males is from 53.0 years in the Northern Territory to 58.0 years in New South Wales; for females it is from 58.0 years in the Northern Territory and Western Australia to 65.0 years in New South Wales [1].

Notes:

Deaths data

For deaths data released since 2007, the ABS has applied a staged approach to the coding of cause of death which affects the number of records available for release at any date. In each release, the latest year’s data is preliminary, the second latest is revised and the data for the remaining years is final. For further information about the ABS revisions process see the following and related sites: http://www.abs.gov.au/ausstats/abs@.nsf/Lookup/3303.0Explanatory+Notes12012.

Data quality

Almost all deaths in Australia are registered. However, Indigenous status is not always recorded, or recorded correctly. The incompleteness of Indigenous identification (referred to as completeness of coverage) means that the number of deaths registered as Indigenous is an underestimate of the actual number of deaths which occur in the Indigenous population. It should also be noted that completeness of coverage is likely to vary between geographical areas.

While there is incomplete coverage of Indigenous deaths in all state and territory registration systems, some jurisdictions have been assessed by the Australian Bureau of Statistics (ABS) as having a sufficient level of coverage to enable statistics on Aboriginal and Torres Strait Islander mortality to be produced. Those jurisdictions are New South Wales, Queensland, South Australia, Western Australia and the Northern Territory.
