A pie graph that shows estimated percentages of adults with BMIs within specific ranges. According to the graph, 31.2 percent of adults had BMIs under 24.9 and so were considered normal weight or underweight. Another 33.1 percent had BMIs from 25 to 29.9, and so they were considered overweight. The group with BMIs of 30 or higher—people considered to have obesity—amounted to 35.7 percent. Those considered to have extreme obesity, with BMIs of 40 or higher, amounted to 6.3 percent.
