This figure characterizes the dramatic geographic differences in T1D incidence.  Countries with the highest incidence include Finland, Sardinia, and the Scandinavian countries.  Those with lowest are found in Asia.  In addition, Native-Americans and some populations in Latin America have an extremely low incidence of the disease. The dramatic difference in T1D incidence worldwide are likely related to variations in the prevalence of the genetic and environmental risk factors for the disease.
