Type 1 diabetes by US state

An estimated 1,476,859 people in the United States were living with type 1 diabetes in 2024 (95% CI, 1,427,111–1,526,327), including 196,778 younger than 20. Among people younger than 20, 24.0 in every 100,000 were newly diagnosed that year. The table gives the same figures for each state and the District of Columbia; choose a state for its full profile, including trends to 2040 and life expectancy.
