Almost two-thirds (63%) of the population aged 18 and over are overweight or obese (36% overweight, 28% obese) . Only one-third (35%) of Australian adults have a healthy body weight.
The body mass index (BMI) distribution varies between men and women. The distribution for men peaks at higher BMI values, indicating that overweight/obesity is more common in men (71%) than in women (56%).

The proportion of overweight or obese adults in the population (based on measured height and weight) has increased in recent decades, after taking changes in the age structure into account. The prevalence increased from 57% in 1995 to 61% in 2007–08 and to 63% in 2011–12. There was no significant increase between 2011–12 and 2014–15, with prevalence remaining at 63% [1, 2]. The increase was largely driven by a rise in the level of obesity from 19% to 28% between 1995 and 2014–15, with the proportion of overweight but not obese adults remaining similar (38% to 35%) over the same period.
Between 1995 and 2014–15, the relative increase in the proportion of overweight or obese adults was higher in women (12%) than men (8.8%). However, the gap between men and women has remained similar.

The level of overweight and obesity in adults varies according to geographical location and is higher outside of Major cities. In 2014–15, around three-quarters of men living in Inner regional (75%) and Outer regional and remote (74%) areas were overweight or obese compared with 69% of men living in Major cities. Around two-thirds of women living in Inner regional (63%) and Outer regional and remote (64%) areas were overweight or obese compared with just over half (53%) of women who live in Major cities.
The level of overweight and obesity also varies according to socioeconomic group for women. Almost two-thirds (61%) of women in the lowest socioeconomic group were overweight or obese, compared with almost half (48%) of those in the highest socioeconomic group. For men, however, the proportions of overweight or obesity were similar in each socioeconomic group, ranging from 69% to 73%.

Based on data for 2015 or the closest available year for people aged over 15 years, more than half (54%) of adults in Organisation for Economic Cooperation and Development (OECD) countries are overweight or obese (based on self-reported or measured data) . Australia’s rate of obesity (28% of the population aged 15 and over) is fifth highest among 41 OECD countries, behind the United States (38%), Mexico (32%), New Zealand (31%) and Hungary (30%). The average rate of obesity among OECD countries is 19%. Japan has the lowest rate obesity at 3.7%.

Results from the ABS 2014–15 National Health Survey show that about one-quarter (26%) of children aged 2–17 were overweight or obese, with 18% being overweight and 8.0% obese. The proportion of boys and girls who were overweight or obese was similar (27% compared with 25%).
Rates of overweight and obesity were similar across age groups, ranging from 20% for children aged 2–4 to 33% for adolescents aged 16–17. Boys aged 16–17 had the highest obesity rate (8.2%), and obesity among girls was most common at ages 5–7 (12%).
The proportion of children and adolescents aged 5–17 who were overweight or obese increased between 1995 and 2007–08 (21% and 25%, respectively) then remained stable to 2011–12 (26%) and 2014–15 (27%) .
