Notes on the data: Aboriginal premature mortality by selected cause

Deaths from road traffic injuries, Aboriginal people aged 0 to 74 years, 2018 to 2022

Policy context: In 2021 to 2022, Indigenous Australians were 1.7 times more likely to be hospitalised due to a transport accident than non-Indigenous Australian, and 2.8 times more likely to die in a transport accident than non-Indigenous Australians [1]. Over 90% of Aboriginal and Torres Strait Islander land transport fatalities and about 66% of serious injury cases occurred in traffic [2].

Some 3.1% of all deaths of Aboriginal people occurring before 75 years of age were due to road traffic injuries.

The data show that, for 2018 to 2022, almost all (99%) deaths of Aboriginal and Torres Strait Islander people from external causes occurred before 75 years of age (one and a half times the proportion for non-Indigenous Australians), 96.1% before 65 years and 88.4% before 55 years – details here. This was higher than the proportion for the non-Indigenous population at ages 0 to 74 years (94.4% c.f. 87.0%).

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 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.
