Diabetes prevalence is an important population health indicator used to compare the burden of diabetes across countries and territories. The 2026 diabetes rates by country ranking shows the percentage represented as living with diabetes in the supplied dataset and allows countries with very different population sizes to be compared using the same percentage-based measure. The ranking reveals substantial international variation, with Pakistan, several Middle Eastern countries and a number of Pacific island countries and territories appearing near the top. Diabetes prevalence can vary between populations because of differences in demographic, lifestyle, metabolic, socioeconomic and health-related factors. The source identified in the supplied dataset is the IDF Diabetes Atlas.
