The number of people with diabetes has nearly quadrupled since 1980.
About 422 million people worldwide have diabetes, a number likely to more than double in the next 20 years.
The prevalence of diabetes has been steadily increasing for the past 3 decades, mirroring an increase in the prevalence of obesity and overweight people. In particular, the prevalence of diabetes is growing most rapidly in low- and middle-income countries.
In 2012, diabetes was the direct cause of 1.5 million deaths. More than 80% of diabetes deaths occur in low- and middle-income countries.
In 2014, 8.5% of adults aged 18 years and older had diabetes.
Type 2 accounts for around 90% of all diabetes worldwide. Reports of type 2 diabetes in children have increased worldwide.
