About 194 million people worldwide, or 5.1%, in the age group 20-79 were estimated to have diabetes in 2003. This estimate is expected to increase to some 333 million, or 6.3% of the adult population, by 2025.
The largest proportional and absolute increase will occur in developing countries, where the prevalence will rise from 4.2% to 5.6%. By 2025, the adult diabetic population is expected to double in India to about 73 million and in China to 46 million. At the same time, diabetes prevalence is expected to increase to 2.8% of the adult population in Africa and 7.2% in South and Central America.
The European Region, with 48 million, and Western Pacific Region, with 43 million, currently have the highest number of people with diabetes. However the prevalence rate of the Western Pacific Region at 3.1% is significantly lower than 7.9% in the North American Region and 7.8% in the European Region as shown in the figure below.
By 2025, the region with the greatest number of persons with diabetes is expected to change to the South-East Asian Region with some 82 million as shown in the figure below. The region's prevalence of 7.5% will however continue to be lower than that of North America, estimated at 9.7%, and Europe at 9.1% (see figure above).
About 45% of adults with diabetes, some 88 milllion, are in the 40-59 year age group. By 2025, because of the ageing of the world's population, there will be 146 million people with diabetes aged 40-59 and 147 million aged 60 or older.
The estimates for both 2003 and 2025 showed a female predominance in the number of persons with diabetes. The female numbers were about 10% higher than for males.
In 2003 the number of people with diabetes in urban areas was 78 million, compared to 44 million persons with diabetes in rural areas in countries not considered to be Established Market Economies, or Former Socialist Economies. By 2025 it is expected that the numbers will increase to 182 million in urban areas and 61 million in rural areas.
