Notes on the data: Aboriginal median age at death

Median age at death of Aboriginal people, 2018 to 2022

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 2018 to 2022, 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 59.0 years for males and 64.0 years for females [1]. The range in median age for males is from 55.0 years in the Northern Territory to 62.0 years in New South Wales; for females it is from 61.0 years in Western Australia and the Northern Territory to 67.0 years in New South Wales [1].

Notes:

Deaths data

For deaths data released since 2007, the Australian Bureau of Statistics (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 general, 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.

However, data published here are from the following releases: 2018, 2019 and 2020 final; and 2021 and 2022 preliminary.

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.
