India holds second place behind China in terms of the number of people affected with diabetes mellitus. Since the people affected with diabetes are increasing, the statistics will continuously change, and frequent updating is needed.
The prevalence of diabetes between the age of 20-79 years in India (IDF 2019 data) is 8.9 %.
This corresponds to total diabetes cases in adults as 77,005,600, and it is expected to reach 100 million by 2030.
Among this, 57% are previously undiagnosed diabetes. Presently India contributes to 1 in 6 adults with diabetes in the world.
The prevalence of elderly diabetes (Aged > 65) is also on the rise.
The number of people with diabetes aged more than 65 is 12 million as per 2019 data, and it is supposed to increase to 18 million by 2030.
The incidence and prevalence of type 1 diabetes is also increasing. The number of new-onset type 1 diabetes between 0-14 years is 15.9, and prevalence is 95.6 (in thousands).
The state-wise prevalence of diabetes in India is variable due to cultural, dietary and lifestyle differences.

It is also more urban (11.2%) than in the rural population (5.2%).
