Numbers and rates of deaths by suicide change over time as social, economic and environmental factors influence suicide risk. The data visualisations below provide an overview of the characteristics of people who have died by suicide in Australia since 1907, looking at trends and variations by sex and age—how many there were, how old they were when they died, and the methods used over time. This analysis may provide useful information on potentially preventable factors, such as restricting access to means of suicide and reducing the risks posed by social or economic factors. Over time, the accuracy and quality of the data collected have been influenced by a number of factors including changes in legislation, technology and a reduction in social stigma.
Suicide deaths by sex, Australia, 1907 to 2019.
The line graph shows age-standardised rates of suicide for males, females and persons from 1907 to 2019. Users can also choose to view the number of deaths by suicide and male to female rate ratios from 1907 to 2019 and median age at death by sex from 1964 to 2019. The data can be viewed for any period between the years for which data are available. The visualisation includes text boxes with numbers and rates of deaths by suicide in Australia in 2019 for persons, males and females. In 2019, there were 3318 suicide deaths recorded at a rate of 12.9 deaths per 100,000 population; there were 2502 deaths by suicide for males, with a rate of 19.8 and 816 for females, with a rate of 6.3.
Numbers of deaths by suicide increased steadily over the first half of the 20th Century (from 461 in 1907 to 760 in 1950), with peaks and troughs in numbers of suicides corresponding with significant world events (see below). However, since the 1950s numbers of deaths by suicide increased more steeply over time—in part driven by population growth. Peaks in numbers of deaths by suicide occurred during the 1960s and late 1990s. Since the mid-2000s numbers of deaths by suicide in Australia have increased to about 3,000 Australians dying by suicide each year.
Between 1907 and 2019, age-standardised suicide rates in Australian ranged from 8.4 deaths per 100,000 population per year (in 1943 and 1944) to 18.4 in 1963.
It is important to note that deaths by suicide were underestimated in the collection of routine deaths data, particularly in the years before 2006 (AIHW: Harrison et al 2009; De Leo, 2010; AIHW: Harrison & Henley 2015). Since then, the Australian Bureau of Statistics (ABS) has introduced a revisions process to improve data quality by enabling the revision of cause of death for open coroner’s cases over time. Deaths registered in 2019 and 2018 are preliminary and data for 2017 are revised and therefore, data for these years are subject to further revision by the Australian Bureau of Statistics. Data from 1907 to 2016 are final (for further information see Technical notes).
Trends in suicide rates, especially recent trends—over the last 10 years, are a matter of public and policy interest. However, interpretation of trends and changes in rates is complicated by large yearly variation due to small numbers of deaths by suicide. Caution is advised when making year to year comparisons.
While an individual’s reasons are personal and often complex, overall peaks and troughs in rates and numbers of deaths by suicide coincide—more or less—with social and economic events.
Falls in the male suicide rate coincided with both World Wars 1 and 2. These falls are at least partly a statistical artefact due to the fact that deaths from all causes (including deaths by suicide) of Australian service personnel while overseas were not included in Australian death registration data, while population estimates were not adjusted to allow for the absence of these personnel (AIHW 2005; AIHW: Harrison & Henley 2014).
The highest annual age-standardised rate for males in the last century occurred in 1930 (29.8 deaths per 100,000 population), during the Great Depression—a period of high unemployment, particularly among males. The rise in both male and female suicide rates in the 1960s has been attributed, in part, to the unrestricted availability of barbiturate sedatives (Oliver & Hetzel 1972; Whitlock 1975). Subsequent falls in these rates in the late 1960s and early 1970s have in turn been attributed to the introduction of restrictions to the availability of these drugs in July 1967 (AIHW: Harrison & Henley 2014). High rates of suicide in the late 1980s and early 1990s coincide with a period of economic uncertainty in Australia.
Since 1907, the male age-standardised suicide rate has been consistently higher and more variable than the female rate. Variations in the overall suicide rate in Australia have been largely driven by changes in the male suicide rate.
The peak in overall suicide rates in 1930 was driven by an increase in male suicide rates, peaking at 29.8 deaths per 100,000 in 1930—the highest rate ever recorded. Similarly, the increase in overall suicide rates in the 1990s was also mainly driven by an increase in male rates. The peak in the 1960s reflects a rise in suicide rates for both males and females.
The male suicide rate ranged from a high of 5.6 times that of females in 1930 to lows of less than twice the female rate in the 1960s and early 1970s—mainly due to the marked rise in female suicide rates at this time. Since then, the male suicide rate has fluctuated around 3–4 times that of the female rate.
Although males are more likely to die by suicide, females are hospitalised for intentional self-harm (with and without suicidal intent) almost twice as frequently as males (see Intentional self-harm hospitalisations). Furthermore, early indications from ambulance attendance data reporting on attendances for suicide attempts in 2019 suggest females are more likely to attempt suicide than males (see Ambulance attendances, self-harm behaviours and mental health).
Age-specific suicide rates for males are higher than those for females across all age groups for all years. Use the year slider to see how patterns of suicide in males and females have changed in Australia over time. Hover over the graph to display the tooltip to see the trend in deaths by suicide by sex over time for each age group.
A more detailed breakdown by 5-year age groups is provided for the most recent suicide data from 2018: see Australia’s Health Suicide and intentional self-harm snapshot. The highest proportion of deaths by suicide occur during mid-life. More than half of all deaths by suicide (55%) in 2019 occurred in people aged 30–59 (1,816 deaths) compared with 23% for those aged 15–29, and 21% for those aged 60 and over. Some of the highest suicide rates for both males and females occur in their 40s; in 2019, the highest suicide rates were in males aged 45–49 (32.2 deaths per 100,000 population) and 85 and over (32.3) and in females aged 40–44 (9.7).
Suicide deaths by age and sex, Australia, 2019.
The butterfly chart shows the age-specific rates of suicide for males and females by age groups (15–19, 20–39, 40–59 and 60 and over). Users can also choose to view numbers of deaths by suicide for males and females in these age groups. Data can also be viewed by year from 1907. In 2019, age-specific suicide rates were much higher in males than females for all age groups, and the highest rates were in males aged 40–59, at 28.8 per 100,000 population.
For approximately the first half of the period 1907 to 2019, age-specific suicide rates in males generally increased with age; however, by the start of the 1990s this pattern had changed substantially with suicide rates highest in younger males aged 20–39. Since 2008, the highest suicide rates have been observed in middle-aged males (aged 40–59).
Throughout 1907 to 2019, the lowest suicide rates in males were observed in those aged 15–19.
Males aged 20–39 had the second-lowest age-specific suicide rates for most of the 20th Century; however, during the late 1980s and throughout the 1990s this age group had the highest suicide rates.
The pattern of age-specific suicide rates for middle-aged males (aged 40–59) was different to that of younger age groups, with the highest rates being observed in the first part of the 20th Century and then falling to lower levels.
A similar pattern was seen in males aged 60 and older.
Age-specific suicide rates for females showed comparatively little variation over time—except for a peak in multiple age groups during the 1960s.
Understanding the methods used for suicide can play an important role in suicide prevention. These data are provided to inform discussion around restriction of access to means as a policy intervention for the prevention of suicide.

The pattern of methods used for suicide has changed greatly, sometimes rapidly, over the last century as new methods have become available or as restrictions to the availability of some methods have been introduced. The methods of suicide used by males and females differed over the period 1907 to 2019; however, as males account for the majority of deaths by suicide the methods used by males have a greater influence on the overall pattern than the methods used by females.
The classification system used to code causes of deaths data, ICD-10, uses the term ‘mechanism’ to refer to the external cause of death. Throughout Suicide & self-harm monitoring ‘mechanism’ has been used in data visualisations, while the term ‘method’ has been used in the accompanying text.
Suicide deaths by sex and mechanism, Australia, 1907 to 2019.
The line graph shows age-standardised suicide rates by mechanism for poisons, gas, firearms, hanging and other mechanisms from 1907 to 2019. Users can also choose to view age-standardised rates and numbers of deaths by suicide, by sex and mechanism (including all mechanisms) from 1907 to 2019 and median age at death by sex and mechanism from 1964 to 2019. The data can be viewed for any period between the years for which data are available. The highest suicide rates by mechanism between 1907 and 2019 were for poisons in the 1960s, at around 7 to 8 deaths per 100,000 population falling steeply throughout the 1970s to below 3 from 1981. Around this time, suicide rates by hanging began to rise steeply, becoming the highest by mechanism after 1988 and more than doubling from 3.2 deaths per 100,000 population in 1988 to 7.8 in 2019.
Hanging (ICD-10 X70) has become the most common method of suicide in Australia and use of this method increased substantially over the last 25 years. Age-standardised rates of suicide by hanging remain much higher for males than females, but have increased for both sexes.
Use of firearms (ICD-10 X72–X75) was the most common method of suicide for males from 1907 to the late-1980s.
In the 1920s, poisoning by gas (ICD-10 X67), largely due to carbon monoxide poisoning, became a new method of suicide in Australia with the introduction of the domestic gas supply and the motor vehicle to Australia.
Exposure to poisonous substances excluding gas (ICD-10 X60–X66, X68–X69) was the most common method of suicide for females from 1907 until 1997.
Age-standardised rates for suicides by other methods (ICD-10 X71, X76–X84, Y87.0) are only available from 1964.
