What this means

An estimated 19,114 adults in Walsall have high blood pressure without knowing it — on top of those diagnosed. That is why blood-pressure checks in pharmacies, GP surgeries and community events matter.

95% confidence interval: 8.1–9.2 %. Source population denominator: 223,422 (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.
  • Built from Health Survey for England blood-pressure measurements and reported diagnosis, then modelled to local populations.
  • Blood-pressure threshold used: 140/90 mmHg or above.
  • Lower means fewer adults walking around with unknown high blood pressure.

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