What this means
An estimated 8.2% of adults in Barnet 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: 8.0–8.4 %. Source population denominator: 309,289 (Persons, 16+ yrs); this measure is modelled, not a direct count of cases.
A modelled 2021 estimate, shown for context — not compared to England.
