Brittle Type 1 Diabetes Statistics            Updated 12/12/2020



Number of individuals with Brittle Type 1 Diabetes in the USA estimated by BDF is based on numbers provided by the Center for Disease Control (CDC) National Diabetes 2017 Fact sheet  which is based on actual 2015 data in most instances)


Between 1980 and 2012 the number of diagnosed cases of diabetes in the USA nearly quadrupled from 5.5 to 21.3 million. 1.7 million new cases in adults are diagnosed each year. (based on 2012 statistics)


There are approx.  30.3 million people with diabetes including 7.2 million undiagnosed individuals and 23.1 million diagnosed.


Breakdown by age as a percentage of the whole (30.3 million people):


< 18 years of age     -        1.0 %

   19 – 44                        14.7 %

   45 – 64                        45.8 %

 >65                               38.5 %

The literature is replete with estimates for type 1 diabetes (T1D) ranging from 5%  to 10% of all those diagnosed with diabetes . According to the CDC - Type 1 diabetes accounts for approximately 5% of all diagnosed cases of  Diabetes which equals 1.15 million with type 1 diabetes. If you include undiagnosed the number jumps to 1.51 million with type 1 diabetes. 

Recent estimates suggest that some 70,000 people have been diagnosed with BT1D. It is difficult to imagine a person with brittle diabetes who remains undiagnosed. 


Brittle diabetes is obviously a very rare form of Type 1 diabetes.


For every 4,700 people in the USA you should find a person exhibiting Brittle Diabetes symptoms, making it extremely rare.


Cost of diabetes to the US economy - $266 billion as of 2017. and $825 Billion globally based on the latest 2018 Harvard University study. Diabetes is expected to become a one trillion dollar industry in 2020.
