Diabetes facts and figures show the growing global burden for individuals, families, and countries. The IDF Diabetes Atlas (2021) reports that 10.5% of the adult population (20-79 years) has diabetes, with almost half unaware that they are living with the condition.

By 2045, IDF projections show that 1 in 8 adults, approximately 783 million, will be living with diabetes, an increase of 46%. 

Over 90% of people with diabetes have type 2 diabetes, which is driven by socio-economic, demographic, environmental, and genetic factors. The key contributors to the rise in type 2 diabetes include:

  • Urbanisation
  • An ageing population
  • Decreasing levels of physical activity
  • Increasing overweight and obesity prevalence

However, it is possible to reduce the impact of diabetes by taking preventive measures for type 2 diabetes and providing early diagnosis and proper care for all types of diabetes. These measures can help people living with the condition avoid or delay complications.
