The T1D Index reveals the global scope and impact of type 1 diabetes.

A first-of-its-kind lifesaving tool

The T1D Index is a first-of-its-kind data simulation tool that provides the most accurate and comprehensive global picture of type 1 diabetes (T1D) in history. The Index measures and maps how many people live with this condition in every country on earth, the healthy years of life it takes from people living with T1D, the number of people who would still be alive today if they hadn’t died prematurely from T1D complications, and our global strategy to reduce its impact.

T1D has never before been measured in this way, at this scale, with this degree of accuracy.

Numbers from the T1D Index

1 in 30 families in the United States are affected by T1D.

Globally, people with T1D lose an average of 32 healthy years of life because of the condition.

For every two people living with T1D, we miss a third who passed away from T1D too soon. 

The interventions recommended by the T1D Index have the potential to improve the lives of millions of people with T1D.”

Changing the numbers

We can take action to improve and save lives through four key interventions:

Timely diagnosis

If we could promptly diagnose everyone affected by type 1 diabetes, 668,000 more people could be alive in 2040.

Insulin and strips

If everyone globally had access to insulin, test strips, and good self-management tools, 1.98 million more people could be alive in 2040.

Pumps and CGMs

If everyone globally had access to technology that automates glucose monitoring and insulin delivery, 673,000 more people could be alive in 2040.

Prevention and cures

By researching and investing in emerging treatments and cures, we could restore full length and quality of life to everyone who develops T1D.
