How Has the Incidence of Diabetes Changed over Time?

The incidence of diabetes more than doubled from 1980-2011, with more than 314 million people worldwide diagnosed with diabetes. Although as much as 30 percent of this increase might be caused by increased diagnosis, the trend was expected to continue at least through 2030. Worldwide, about 10 percent of men have diabetes, and about 9 percent of women have diabetes.
