Limitations
Contact | Website diabetesatlas.org
 Our definition of diabetes is based on an epidemiological definition. We therefore require only one abnormal
glucose value, compared to a clinical diagnosis, where abnormal glucose across two tests is required to make a
diagnosis
 Raw data is subject to heterogeneity in terms of calendar year, diagnostic method, representativeness and
precision of the study design. While we attempt to address this using analytic hierarchy process, bias may still be
present
 For countries without in-country data, diabetes prevalence is extrapolated based on data from a country with
similar demography, economy and language group. This may introduce error
 There is a dearth of data from the African region
 For our projections, we only consider demographic changes in age, sex and urbanisation. We do not take into
account other factors that may influence diabetes incidence

Summary
 In 2021, the IDF 10 Edition of the Atlas estimates that 1/10 people aged 20-79 have diabetes
 This equates to 537 million people in the world
 By 2045, this number will increase to 784 million
 There still remain gaps in our estimates due to absent and low-quality data in some parts of the
world
 There is a strong need for effective intervention strategies and policies to stall the increase in the
number of people developing diabetes
