Globally as of 2010 it was estimated that there were 285 million people with type 2 diabetes making up about 90% of diabetes cases. This is equivalent to about 6% of the world's adult population. Diabetes is common both in the developed and the developing world. It remains uncommon, however, in the underdeveloped world.

Women seem to be at a greater risk as do certain ethnic groups, such as South Asians, Pacific Islanders, Latinos, and Native Americans. This may be due to enhanced sensitivity to a Western lifestyle in certain ethnic groups. Traditionally considered a disease of adults, type 2 diabetes is increasingly diagnosed in children in parallel with rising obesity rates. Type 2 diabetes is now diagnosed as frequently as type 1 diabetes in teenagers in the United States.

Rates of diabetes in 1985 were estimated at 30 million, increasing to 135 million in 1995 and 217 million in 2005. This increase is believed to be primarily due to the global population aging, a decrease in exercise, and increasing rates of obesity. The five countries with the greatest number of people with diabetes as of 2000 are India having 31.7 million, China 20.8 million, the United States 17.7 million, Indonesia 8.4 million, and Japan 6.8 million. It is recognized as a global epidemic by the World Health Organization.
