Diabetes Statistics

This content describes the prevalence of diabetes, prediabetes, and gestational diabetes in the United States.

Diabetes Facts and Statistics

Diabetes occurs when your blood glucose, also called blood sugar, is too high. High blood glucose can cause health problems over time. The main types of diabetes are type 1, type 2, and gestational. Learn more from the Diabetes Overview.

  • Total: An estimated 34.2 million people have diabetes (10.5 percent of the U.S. population).
  • Diagnosed: An estimated 26.9 million people of all ages have been diagnosed with diabetes (8.2 percent of the U.S. population).
    • Of the people diagnosed with diabetes, 210,000 are children and adolescents younger than age 20 years, including 187,000 with type 1 diabetes.
  • Undiagnosed: An estimated 7.3 million adults ages 18 years or older have diabetes but are undiagnosed (21.4 percent of adults with diabetes).

According to the American Diabetes Association’s Economic Costs of Diabetes in the U.S., the total estimated cost of diagnosed diabetes in 2017 was $327 billion, including $237 billion in direct medical costs and $90 billion in reduced productivity.

Prediabetes Facts and Statistics

Prediabetes is a condition in which blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes. Prediabetes usually occurs in people whose bodies may not be able to effectively use the insulin they make or their pancreas may not produce enough insulin to keep their blood glucose levels in the normal range. People with prediabetes are at increased risk of developing type 2 diabetes. Learn more about prediabetes.

  • An estimated 88 million adults ages 18 years or older (34.5 percent of U.S. adults) have prediabetes. This includes
    • nearly 29 million adults ages 18 to 44 years (24.3 percent of U.S. adults in this age group)
    • more than 35 million adults ages 45 to 64 years (41.7 percent of U.S. adults in this age group)
    • more than 24 million adults ages 65 or older (46.6 percent of U.S. adults in this age group
  • More men (37.4 percent of U.S. adults) than women (29.2 percent) have prediabetes.
  • The prevalence of prediabetes is similar among men and women across racial and ethnic groups and education levels.
  • Among adolescents ages 12 to 18 years, more than 1 in 6 (18 percent of U.S. adolescents) have prediabetes.1

Gestational Diabetes Facts and Statistics

Gestational diabetes is a type of diabetes that develops during pregnancy in women who don’t already have diabetes. High blood glucose levels during pregnancy can cause problems for the mother and the baby, and they can increase the chance of having a miscarriage. Learn more about gestational diabetes.

  • About 6 percent of U.S. women who gave birth in 2016 had gestational diabetes.2
  • About 50 percent of U.S. women with gestational diabetes go on to develop type 2 diabetes.3
