The story of Australia in numbers

In 2024, about 30.6% of adults in Australia were living with obesity — about 1 in 3 adults, according to World Health Organization estimates (the likely range is 27.2% to 34.2%). That is roughly 6.8 million people aged 18 and over.

That is higher than the world average of 16.2%, and ranks 62nd highest out of 199 countries. It is above the average for WHO’s Western Pacific region (9.7%).

Back in 1980, the figure was 7.6%. Since then it has gone up by 23.0 percentage points — about 4.0 times the 1980 level. In people, that is a change from about 766 thousand to 6.8 million adults, partly because the population itself changed.

Men are more likely to live with obesity than women: 31.4% compared with 29.7%.

Among children and teenagers aged 5 to 19, 16.4% were living with obesity in 2024, compared with 2.4% in 1980 — around 796 thousand young people.

For context, 8.1% of adults had diabetes in 2022, 25.5% of adults did not get enough physical activity in 2022 and the food supply provided about 3,562 calories per person per day in 2023. These numbers don’t prove what causes obesity, but they help paint the picture.
