“Among the U.S. population overall, crude estimates for 2021 were:

• 38.4 million people of all ages—or 11.6% of the U.S. population—had diabetes.
• 38.1 million adults aged 18 years or older—or 14.7% of all U.S. adults—had diabetes (Table 1a; Table 1b).
• 8.7 million adults aged 18 years or older who met laboratory criteria for diabetes were not aware of or did not report having diabetes (undiagnosed diabetes, Table 1b). This number represents 3.4% of all U.S. adults (Table 1a) and 22.8% of all U.S. adults with diabetes.
• The percentage of adults with diabetes increased with age, reaching 29.2% among those aged 65 years or older (Table 1a).”
