The interactive graphs below allow you to explore how the prevalence of overweight and obesity has changed over time in different populations, using nationally representative measured height and weight data.
National data on overweight and obesity among 5–17 year olds are available from national health surveys conducted by the ABS, dating back to 1995.
The proportion of children and adolescents who were overweight or obese increased between 1995 and 2007–08 (from 20% to 25%), then remained relatively stable from 2007–08 to 2017–18 (ABS 2009b, 2013a, 2013b, 2015, 2019b) (Figure 1).
Similarly, the prevalence of obesity increased from 4.9% in 1995 to 7.5% in 2007–08, then remained relatively stable to 2017–18 (8.1%). Rates of overweight but not obese children rose between 1995 and 2014–15 (from 15% to 20%), then declined to 17% in 2017–18.
