Notes on the data: Premature mortality by selected cause - 0 to 74 years

Deaths from suicide and self-inflicted injuries, persons aged 0 to 74 years, 2016 to 2020

Policy context:  Suicide is a major public health issue. Although death by suicide is relatively uncommon (approximately 1.7% of deaths), the human costs are substantial and can impact broadly across communities. As such, suicide prevention is a key focus for both government agencies and non-government organisations [1]. There were 28,718 suicide deaths registered in Australia over the ten years from 2011 and 2020. Suicide accounted for 1.8% of the 1,562,847 deaths due to all causes which occurred over this period [2]. The age-standardised suicide rate in 2010 was 10.5 deaths per 100,000 population; by 2020 it was higher, at 12.2 deaths per 100,000 population. Males were just over three times more likely to die from suicide than females across 2020 [3]. However, the distribution of suicide deaths across ages to the 75 to 84 year age group was similar for males and females [3]. Suicide accounts for a large proportion of deaths of people between 15 and 24 years of age, and 25 and 34 years of age.

For 2016 to 2020, 92.3% of deaths from suicide were premature - 92.5% for males and 91.8% for females: details here.

The indicator Potential Years of Life Lost (click here ) adds a further dimension to the data on premature death, in particular from these causes, which include deaths of many young people.

Notes:  There are concerns regarding the quality of data on suicides, some of which may have been counted as deaths from other accidental, ill-defined or unspecified causes rather than suicide; and numbers are subject to revision as coronial enquires are completed.

International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) codes: X60-X84, Y87.0

For deaths data released since 2007, 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.
