ABS says dementia accounted for more than one in ten Australian deaths in 2025
The October 27 release reports 19,019 deaths from dementia, including Alzheimer’s disease, in Australia’s 2025 cause-of-death statistics.
What the record says
The Australian Bureau of Statistics says dementia’s share of deaths exceeded 10% for the first time, compared with 5% in 2006.
Women accounted for 61.1% of dementia deaths in 2025. ABS explains that its leading-cause rankings use the underlying cause of death; other conditions listed on death certificates are counted separately in multiple-cause tables.
