Prevalence and Incidence

The prevalence figures by the CDC are estimates compiled from their own data systems, outpatient databases (Indian Health Services – HIS), US Renal Data Systems (NIH), US Census Bureau and published studies.4 A question on pre-diabetes was included for the first time in the 2006 National Health Interview Survey given to a representative sample of households; approximately 24,300 adults of the ages 18 and older.24

In 2015, approximately 30.3 million Americans or 9.4% of the population, have diabetes: increased from 5.1% in 1997.4,25,53,55 Of these, 23.1 million people are diagnosed with diabetes and 7.2 million people are undiagnosed.55 Pre-diabetes is becoming more common in the United States: the U.S. Department of Health and Human Services estimates one in three U.S. adults aged 18 years or older, or 84.1 million people, had pre-diabetes in 2015.6,53 In addition, 1.5 million new cases of diabetes were diagnosed in people aged 18 years or older in 2015.4,53

Figure 1. American Diabetic Status.

In 2015, approximately 193,000, or 0.24% of all people under 20 years of age have diagnosed diabetes.55 About one in every 400 children and adolescents has diabetes.53

Although type 2 diabetes can occur in youth, the national representative data necessary to monitor diabetes trends in youth by type is not available. Clinically-based reports and regional studies suggest that type 2 diabetes, although still rare, is being diagnosed more frequently in children and adolescents, particularly in American Indians, African Americans, and Hispanic/Latino Americans.4,53

As of 2015, approximately 23.1 million, or 7.2% of all people aged 20 years and older have either diagnosed or undiagnosed diabetes, and 11.2 million, or 25.9% of all people 65 years or older have diabetes.4,53,55

As of 2015, approximately 15.3 million, or 12.7% of all men aged 20 years or older have diabetes although nearly one third of them are unaware of their condition.4,53,55

And as of 2015, approximately 14.9 million, or 11.7% of all women aged 20 years or older have diabetes and again nearly one-third are unaware. The prevalence of diabetes is higher among non-Hispanic Black, Hispanic/Latino American, American Indian, and Asian/Pacific Islander women than among non-Hispanic white women.4,53,55
