Expected diabetes prevalence (diagnosed and undiagnosed) for England in 2015 by gender, ethnicity, and age group.5 A Public Health England (PHE). Diabetes Prevalence Model. Public Health England, September 2016. Contains public sector information licensed under the Open Government Licence v3.0. The 2016 PHE diabetes prevalence model incorporates more up-to-date data sources and population estimates than previously published diabetes prevalence models. The previous model published in 2012 underestimated undiagnosed diabetes, suggesting that the overall prevalence estimates were probably low.
