The Facts

Prevalence: In 2025, 9.5 million people are living with type 1 diabetes worldwide, and that number is rising rapidly. By 2040, the global T1D population is projected to reach 14.7 million, up from about 2 million in 1990.
Diagnosed and undiagnosed: Of the 38.4 million adults with diabetes, 29.7 million were diagnosed, and 8.7 million were undiagnosed.
Prevalence in seniors: The percentage of Americans age 65 and older remains high, at 29.2%, or 16.5 million seniors (diagnosed and undiagnosed).
New cases: 1.2 million Americans are diagnosed with diabetes every year.
Burden of disease: On average, a person with type 1 diabetes loses 34 years of healthy life, reflecting the lifelong physical, emotional, and financial toll of the disease.

Impact of timely diagnosis: If everyone affected by type 1 diabetes were diagnosed promptly, 393,000 more people could be alive by 2040.

Access to insulin and supplies: If everyone worldwide had access to insulin, test strips, and basic self-management tools, 1.35 million additional lives could be saved by 2040.

Access to technology (pumps and CGMs): If people everywhere had access to glucose-monitoring and insulin-delivery technology, 741,000 more people could be alive by 2040.

Prevention and cures: With continued research and investment in emerging treatments and cures, it is possible to restore full length and quality of life to everyone who develops type 1 diabetes.

Diabetes by race/ethnicity
The rates of diagnosed diabetes in adults by race/ethnic background are:

• 13.6% of American Indians/Alaskan Native adults

• 12.1% of non-Hispanic black adults

• 11.7% of Hispanic adults

• 9.1% of Asian American adults

• 6.9% of non-Hispanic white adults

Common Complications

Living with Type 1 Diabetes involves managing not just daily blood sugar levels but also being vigilant about potential long-term complications. These complications can include cardiovascular disease, nerve damage (neuropathy), kidney damage (nephropathy), eye damage (retinopathy), and foot damage. Awareness and proactive management of Type 1 Diabetes are essential to minimizing these risks and ensuring a healthy, fulfilling life.

Deaths
Diabetes was the eighth leading cause of death in the United States in 2021, based on the 103,294 death certificates in which diabetes was listed as the underlying cause of death. In 2021, diabetes was mentioned as a cause of death in a total of 399,401 certificates. 34 years of healthy life lost on average per person.

Cost of Diabetes
$412.9 billion: Total cost of diagnosed diabetes in the United States in 2022
$306.6 billion was for direct medical costs, $106.3 billion was in indirect costs

After adjusting for population age and sex differences, average medical expenditures among people with diagnosed diabetes were 2.6 times higher than what expenditures would be in the absence of diabetes.
