Leading Causes of Death in Australia
The way Australians live has changed, and so have our leading causes of death. Understanding mortality rates and how to reduce them is vital to maintaining a healthy future.
Leading Causes of Death
The leading causes of death in high-income countries, like Australia, according to The World Health Organization in 2020, were:
- Ischaemic Heart Disease
- Alzheimer’s disease or other dementias
- Trachea, Bronchus, and Lung Cancers
- Chronic Obstructive Pulmonary Disease
- Lower respiratory infections
- Colon and Rectum Cancers
- Kidney Diseases
- Hypertensive Heart Disease
- Diabetes Mellitus
Between 2000 and 2019, the number of deaths caused by strokes and ischaemic heart disease decreased, yet 2.9 million people died from it in 2019. Alzheimer’s overtook stroke as the second highest cause of fatality within Australia in 2019. Globally, Alzheimer’s was responsible for 65% of deaths among women that year.
The causes of death have changed dramatically in the last two decades. Deaths from HIV/Aids have been reduced by 51% globally, and Kidney disease has risen from the world’s 13th leading cause of death to the 10th.
Mortality had increased overall from 813,000 in 2000 to 1.3 million in 2019.
Intentional Self Harm
The World Health Organization reported that 800,000 people died from suicide worldwide in 2016. Suicide is a serious issue affecting people of all ages, and the highest proportion of deaths by suicide occurs among young and middle-aged adults.
In 2018, 75% of people who died from suicide were male (AIHW,2021).
