Prevalence of Diagnosed Diabetes
Among people of all ages, 2015 data indicated the following:
- An estimated 23.1 million people—or 7.2% of the U.S. population—had diagnosed diabetes (Methods) (see Table 1b in the Appendix for more details).
- This total included:
- 132,000 children and adolescents younger than age 18 years (0.18% of the total U.S. population younger than age 18 years).
- 193,000 children and adolescents younger than age 20 years (0.24% of the total U.S. population younger than age 20 years).
- About 5% of people with diabetes are estimated to have type 1 diabetes (Methods).
Among U.S. adults aged 18 years or older, age-adjusted data for 2013–2015 indicated the following:
- American Indians/Alaska Natives had the highest prevalence of diagnosed diabetes for both men (14.9%) and women (15.3%) (Figure 1) (Methods). Prevalence varied by region, from 6.0% among Alaska Natives to 22.2% among American Indians in certain areas of the Southwest.
- Overall, prevalence was higher among American Indians/Alaska Natives (15.1%), non-Hispanic blacks (12.7%), and people of Hispanic ethnicity (12.1%) than among non-Hispanic whites (7.4%) and Asians (8.0%) (see Table 1c in the Appendix for more details).
- Among people of Hispanic ethnicity, Mexicans had the highest prevalence (13.8%), followed by Puerto Ricans (12.0%), Cubans (9.0%), and Central/South Americans (8.5%) (see Table 1c in the Appendix for more details).
- Among Asians, Asian Indians had the highest prevalence (11.2%), followed by Filipinos (8.9%), and Chinese (4.3%). Other Asian groups had a prevalence of 8.5% (see Table 1c in the Appendix for more details).
- Prevalence varied significantly by education level, which is an indicator of socioeconomic status. Specifically, 12.6% of adults with less than a high school education had diagnosed diabetes versus 9.5% of those with a high school education and 7.2% of those with more than a high school education (see Table 1c in the Appendix for more details).

Figure 2 shows model-based county-level estimates of the age-adjusted prevalence of diagnosed diabetes among U.S. adults aged 20 years or older in 2013 (Methods). Specifically, this figure shows that:
- The median age-adjusted county-level prevalence of diagnosed diabetes was 9.4%, with a range of 3.8% to 20.8%.
- Counties in the southern and Appalachian regions of the United States tended to have the highest prevalence of diagnosed diabetes.
