We can never underestimate the impact that every life lost to suicide has on family, friends, workplaces and the broader community. Over 10 million Australian adults are estimated to know someone who has died by suicide, and 1 in 2 young people are impacted by suicide by the time they turn 25. The latest Australian Bureau of Statistics (ABS) data shows that around 8-9 lives are lost per day to suicide.
These statistics are based on 2021 data which was released by the ABS on 19 October 2022.
- Suicide was the 15th leading cause of death overall (the same as in 2020), accounting for 1.8% of deaths.
- 3144 Australians died by suicide in 2021, which represents an age-standardised suicide death rate of 12.0 per 100,000 people.
- The number of suicides has increased slightly, with 5 more deaths in 2021 (compared with 3139 deaths in 2020). However, taking into account Australia’s changing population the rate of suicide has decreased slightly from the 12.1 age-standardised suicide death rate reported for 2020.
- Over the previous ten years the age-standardised suicide death rate per 100,000 people has increased from 11.2 in 2012 to 12.0 in 2021, an increase of 7%
- The median age of death by suicide was 44.8 years, compared to 82.0 years for all causes of death. Because suicide frequently occurs at a younger age than other causes of death the potential years of life lost are high.
- As in previous years, in 2021 suicide was the cause of death resulting in the highest number of potential years of life lost: 107,068 years. This was nearly half again as many years higher as the next most significant cause (Ischaemic heart diseases)
- As in 2020, suicide was the most common cause of death for young people aged 15-24 years. 402 young people aged 15-24 died by suicide, representing 13.0 deaths by suicide per 100,000 people.
- However, this is a decrease from the 454 suicide deaths for young people aged 15-24 in 2020
- Almost one quarter of deaths in those aged 15-44 are due to suicide, the leading cause of death for this age group.
- Consistent with previous years, males are around 3 times more likely to die by suicide than females. Males accounted for 75% of deaths by suicide (2358 deaths), while females accounted for 25% (786 deaths).
- Men aged 50-54 are particularly impacted with 9.1% of suicides of males. They had the highest rates of those aged under 80 years.
Aboriginal and Torres Strait Islander People
- In 2021 there were 219 Aboriginal and Torres Strait Islander peoples who died by suicide across Australia). The age-standardised rate of deaths by suicide amongst Aboriginal and Torres Strait Islander people over 2012 to 2016 and 2017 to 2021 was double – compared to the rate for non-Aboriginal and Torres Strait Islander peoples in the same period.
- The median age of death by suicide of Aboriginal and Torres Strait Islander peoples Australia was 30.2 across Australia, more than a decade younger than the median age of death by suicide for the general population of 44.8 years.
- When looking at State and Territory data, NT had the highest age-standardised rate of deaths by suicide at 18.4 per 100,000
- All states except Queensland and the Australian Capital Territory had decreases in the number of suicides between 2020 and 2021. Queensland (3%) and Australian Capital Territory (14%) reported increases.
- Age-standardised rates of death by suicide were higher in regional Australia: 16.7 deaths per 100,000 outside capital cities, compared with 9.8 deaths per 100,000 in capital cities.
- And rates have increased in regional Australia, up from 15.5 deaths per 100,000 in 2020, while rates in capital cities have fallen from 10.3 deaths per 100,000.
- The proportion of suicide deaths recording at least one risk factor was 90% with psychosocial risk factors being the most commonly reported risk factor (present in almost two-thirds of deaths of people who died by suicide.
- The three most frequently occurring psychosocial risk factors were problems in relationship with spouse or partner (23.2%), personal history of self-harm (22.7%), and disruption of family by separation and divorce (9.7%).
- Mental and behavioural disorders were present in almost 63 percent of deaths of people who died by suicide.
- People who died by suicide had an average of three to four risk factors mentioned.
- 65,000 suicide attempts each year (est.)
- It is estimated that more than 500,000 Australians have attempted suicide at some time in their life.
