The boundaries and names shown and the designations used in this report do not imply the expression of any opinion whatsoever on the part of the International Diabetes Federation (IDF) concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.
There may be some discrepancies between estimates in the IDF Diabetes Atlas and other reported national estimates. This may be due to a difference in sampling methods or populations. The IDF Diabetes Atlas 2015 uses age-stratified data and a consistent methodology to estimate the diabetes prevalence in adults aged 20-79 years, across 220 countries and territories. As a result, other national estimates may report a higher number of diabetes cases.
