What this means

An estimated 10.2% of adults in Blackburn with Darwen have type 2 diabetes — including people who don't yet know it. This cannot be subtracted from the GP-register percentage to estimate undiagnosed cases: the years, age bands, populations and diabetes types differ.

95% confidence interval: 9.8–10.6 %. Source population denominator: 119,734 (Persons, 16+ yrs); this measure is modelled, not a direct count of cases.

Caveats

A 2021 modelled estimate; treat as a ballpark, not a precise count.
Uses 2015–2018 Health Survey for England data applied to the 2021 resident population.
Lower means fewer adults estimated to have type 2 diabetes.

Missing or suppressed values are never shown as zero — every card above passed validation with a real numeric value.
