Japan vs world prevalence of diabetes

The figure describes which age groups in the population have the highest proportions of diabetes. The grey line is the distribution of diabetes prevalence by age for the world; the purple line is the distribution for the region; and the country distribution is plotted in the black line. Many middle- and low-income countries have more people under the age of 60 with diabetes compared to the world average. Meanwhile, for high-income countries, a growing population over the age of 60 makes up the largest proportion of diabetes prevalence.
