Dementia has surpassed heart disease to become the leading cause of death in Australia, according to new data from the Australian Bureau of Statistics (ABS). In 2024, approximately 17,500 Australians died from dementia-related conditions, marking a notable shift in the nation’s health trends.
The data indicates that dementia now accounts for 9.4 percent of all deaths across the country. This increase highlights the growing burden of degenerative brain diseases on families and the healthcare system. The average age of those who died from dementia was 88 years, reflecting the condition’s prevalence among Australia’s ageing population.
Shift in Mortality Patterns
According to Lauren Moran, head of mortality statistics at the ABS, “People are now more likely to live to an age where they have a higher risk of developing dementia.” This trend is particularly evident among women, who generally have longer life expectancies. The data reveals that 62.4 percent of individuals who succumbed to dementia were women.
Furthermore, dementia has been recognized as the leading cause of death for women since 2016. This change in mortality patterns indicates a significant public health concern. Previously, heart disease held the top position for decades, but dementia’s rise underscores a shift that warrants further attention.
Despite this significant change, coronary heart disease continues to be the leading cause of death for men, resulting in 10,153 deaths in 2024. Additionally, it remains the primary cause of death for individuals living in outer regional, remote, and very remote areas of Australia.
Call for Continued Research
The statistics emphasize the urgent need for ongoing research into dementia prevention and treatment, particularly as Australia’s population continues to age. The rising incidence of dementia not only impacts individuals and families but also places increasing demands on the healthcare system.
As the nation grapples with these statistics, the focus must remain on improving care and support for those affected by dementia, as well as advancing research to find effective treatments and preventative measures. The data from the ABS serves as a critical reminder of the challenges posed by this condition and the importance of addressing it in public health discussions.
