Notes on the data: Aboriginal premature mortality by sex

Deaths of Aboriginal females aged 0 to 64 years, 2009 to 2013

Policy context: Around 3,000 Indigenous Australians die each year, resulting in almost 100,000 years of life lost due to premature death [1]. Chronic disease is responsible for a major part of the life expectancy gap; and accounts for some two thirds of the premature deaths among Aboriginal and Torres Strait Islander Australians [2].

The median age at death for Indigenous females in 2013 ranged from 55.3 years for those living in South Australia to 66.2 years for those living in New South Wales [3]. These levels were around 20 years less than those for non-Indigenous females, which ranged between 71.4 years (Northern Territory) and 85.5 years (South Australia).

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.
