The bar chart illustrates the percentage of overweight or obese adults, between 1965 and 2015, while the pie chart provides more details about the bar chart specifically in 2015.
Overall, the percentage of overweight or obese adults increased steadily between 1965 and 2015. In contrast, a relatively small group of people could maintain a healthy weight in 2015.
According to the bar chart, approximately 45 percent of the population was categorized as overweight or obese in 1965. The first significant rise, however, occurred between 1985 and 1995. The figure increased from about 48 percent to 60 percent during that period. In 2015, the number grew even further. Over 70 percent of adults were classified as overweight or obese in that year.
The pie chart supports the data in the bar chart. In the pie chart, slightly over a third (34 percent) of adults fell into the obese category, and 6 percent of them were severely obese. On the other hand, 31 percent of adults were overweight, whereas a smaller proportion (29 percent) was in the healthy weight range.
