The bar chart shows the percentage of the adult population who were overweight or obese between 1965 and 2015, while the pie chart shows the percentage of people who were a healthy weight, overweight, obese and severely obese in 2015. The rise in the number of people who are too heavy was gradual from 1965 to 1985. The first significant increase occurred between 1985 and 199 5, from around 48% to almost 60%. In the next ten-year period there was a similar large rise. By 2005, approximately 70% of people weighed too much. The upward trend continued into the 21st century but at a slightly lower rate.
The pie chart confirms that in 2015 over 70% of adults were too heavy, and it also gives more detail about how much they were overweight. Only 6% of people were so overweight that their health was seriously at risk, i.e. severely obese. The remaining people were divided more or less equally between the other groups.
