Useful statistics

The Mental Health Commission is asked to provide information and statistics on a range of subjects related to mental health and wellbeing, alcohol and other drugs, by the media.

Below is a selection of the key statistics that may be of interest to journalists:

Community impacts

Mental health

One in five Australians aged 16 to 85 years experience mental health issues in any given year (i.e. one of the common forms of mental illness - anxiety, affective or mood disorders, and substance use disorders)

The number of adults in WA with high or very high levels of psychological distress has remained fairly steady in the long term (estimated 7.3% in 2019, similar to previous years.)

Impact on community

For Australia, Mental and substance use disorders were estimated to be responsible for 12% of the total burden of disease in 2015, placing it fourth as a broad disease group after Cancer (18%), Cardiovascular diseases (14%) and Musculoskeletal conditions (13%) (AIHW 2019).

In terms of the non-fatal burden of disease, which is a measure of the number of years of ’healthy’ life lost due to living with a disability, Mental and substance use disorders were the second largest contributor (23%) of the non-fatal burden of disease in Australia, behind Musculoskeletal conditions (25%) (AIHW 2019).

Suicide

Tragically, in Western Australia in 2019:

  • There were 418 registered deaths by suicide, representing 2.8% of total deaths state-wide and 12.6% of all suicide deaths in Australia.
    • 303 were males and 115 females.
    • 313 were in Greater Perth, 110 in the rest of WA
    • 30 were Aboriginal, a decrease from 39 in 2018
    • 49 were young people aged 15 to 24, 184 were between 25 and 44 years old.
  • This represents an increase in the number of registered suicides; 418 compared to 383 in 2018.
  • Despite this decrease, our state continues to have one of the highest rates of suicide in the country. The rate of 16.0 per 100,000 persons in 2019 places Western Australia above the National average (which was 12.9 deaths per 100,000 people).

Between 2016 and 2019, Western Australia had the:

  • Highest age-standardised rate of suicide among Aboriginal and Torres Strait Islander people (34.6 deaths per 100,000 people). This was considerably higher than the national average for Aboriginal and Torres Strait Islander people over this period (23.6 deaths per 100,000 people); and
  • Second highest age-standardised rate of suicide among children aged 5 to 17 years (3.3 deaths per 100,000 people). This was higher than the national average for children aged 5 to 17 over this period (2.4 deaths per 100,000 people).

In 2019, across Australia, 3,318 people died from intentional self-harm (suicide).

  • Of these, 2,502 were by males and 816 by females.
  • The rate of suicide was 12.9 deaths per 100,000 people, an increase from 12.1 deaths per 100,000 people in 2018;
  • Suicide was the 13th leading cause of death for all Australians and the 5th leading cause of death among Aboriginal and Torres Strait Islander people;
  • The rate of suicide among Aboriginal and Torres Strait Islander people in Australia is double the rate for non-Aboriginal and Torres Strait Islander people;
  • There were 96 recorded child suicide deaths and suicide remained the leading cause of death among Australian children 5 to 17 years of age;
  • Mood disorders, including depression, were the most commonly mentioned co-morbidity across all suicide deaths (mentioned in 40.6% of suicide deaths); and
  • Problems related to substance use were present in over one quarter of suicide deaths (28.7%).

Alcohol and other drugs

The 2019 National Drug Strategy Household Survey states, of Western Australians aged 14 years and older: 

  • Most people in WA drank alcohol at levels that did not exceed the lifetime risk and single occasion risk guidelines for reducing health risks from alcohol. The proportion of people exceeding these guidelines (17.2% for lifetime harm and 26% for single occasion risk) was similar to 2016, but declined since 2007.
  • 11.9% smoked tobacco
  • 11.2% used cannabis (down from 11.6% in 2016)
  • 2.9% used ecstasy (down from 3.2%)
  • 2.4% used cocaine (up from 1.6% - but still substantially below the national average of 4.2%)
  • 2.1% used meth/amphetamine (down from 2.7% - still higher than the national average which is 1.3%)
  • 1.7% used pharmaceuticals for non medical purposes (down slightly from 1.8%)
  • 15.6% of Western Australians over 14 reported recently using an illicit drug.

The Alcohol and Other Drug Harm Snapshot Survey found that at the national level in 2019:

  • 13% of emergency department (ED) presentations were alcohol-related and 2.8% of ED presentations were methamphetamine related in Australia;
  • Western Australia consistently had the highest percentage of alcohol-related ED presentations nationally, with more than one in five (22%) ED patients there in relation to alcohol in 2019;
  • All jurisdictions had similar percentages of methamphetamine presentations in 2019 (ranging from 2.0-3.8%). Western Australia reported the largest difference in methamphetamine-related ED presentations in 2019 compared to 2018, reducing from almost 5.9% to 3.3%.
