Notes on the data: Aboriginal premature mortality by selected cause

Deaths from external causes, Aboriginal persons aged 0 to 54, 0 to 64 and 0 to 74 years, 2010 to 2014

 

Policy context:  Deaths from external causes, commonly described as deaths from accidents and injury, are deaths caused by environmental events and circumstances that are external to the body. External causes of death can be classified as 'unintentional', such as transport accidents, falls, and accidental drowning or poisoning; 'intentional', such as suicides and homicides; and those which occur due to the complications of medical and surgical care (commonly referred to as 'adverse events') [1].

In 2014, intentional self-harm, land transport accidents, accidental poisoning and assaults were the fifth, eighth, eleventh and nineteenth leading cause of death among Indigenous peoples living in NSW, Qld, WA, SA and the NT, accounting for 11.9% of all Indigenous deaths [1]. Deaths by intentional self-harm (143 deaths) and land transport accidents (87 deaths) made up 5.2% and 3.2% of all Indigenous deaths, respectively. After age-adjustment, deaths from intentional self-harm were around twice as common for Indigenous people than for other Australians, and those from land transport accidents more than three times as common. After age-adjustment, the death rate for injury from assault was 6.9 times higher (5.7 per 100,000) than for non-Indigenous people (0.8 per 100,000).

Deaths for intentional self-harm, land transport accidents, accidental poisoning and assaults were particularly high among Indigenous people aged 15-24 years and 25-34 years with 72% and 57.3% of all deaths within these age group categories, respectively [1].

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. This release is comprised of preliminary data for 2014, revised data for 2013 and final data for 2010, 2011 and 2012.

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.
