Prevalence of Both Diagnosed and Undiagnosed Diabetes
- An estimated 30.3 million people of all ages—or 9.4% of the U.S. population—had diabetes in 2015 (Methods).
- This total included 30.2 million adults aged 18 years or older (12.2% of all U.S. adults), of which 7.2 million (23.8%) were not aware of or did not report having diabetes (Table 1) (Methods).
- The percentage of adults with diabetes increased with age, reaching a high of 25.2% among those aged 65 years or older (Table 1).
- Compared to non-Hispanic whites, the age-adjusted prevalence of diagnosed and undiagnosed diabetes was higher among Asians, non-Hispanic blacks, and Hispanics during 2011–2014 (see Table 1a in the Appendix for more details).
