Diabetes in England follows the postcode

June 2026 / UK

Diabetes is 3x more common in England's most deprived areas than the least: 14% of adults in the most deprived quintile have diabetes, compared with 5% in the least deprived. Source: Health Survey for England 2024, NHS England, Table 5.

People living in England's most deprived neighbourhoods are nearly three times as likely to have diabetes as those in the least deprived. The Health Survey for England 2024 also confirms a substantial undiagnosed share: around one in five cases.

What the numbers say

Total diabetes prevalence, age-standardised, across the five Index of Multiple Deprivation (IMD) quintiles:

Group

2nd

3rd

4th

Most deprived

Men

7%

15%

Women

All adults

Of that total, the undiagnosed share, adults whose HbA1c is 48 mmol/mol or above but who have never been told they have diabetes, runs at:

What that means

The headline finding is the gradient. Move from the least deprived fifth of England to the most, and the share of adults living with diabetes rises from 5% to 14%. For men, the jump is even sharper, from 7% to 17%. The second-quintile figure for men (15%) is high enough to suggest the relationship is not perfectly linear, but the direction of travel is unambiguous.

For women the picture is cleaner. Prevalence almost triples from the least to the most deprived quintile (4% to 11%), with the steepest rise occurring above the third quintile.

The undiagnosed share is smaller in absolute terms but socially significant: 3% of adults in the most deprived areas are living with diabetes without knowing it, compared with 2% in the least deprived. That gap may look small, but layered on top of an already-higher background prevalence it points to a real diagnostic deficit in the places where the condition is most common.
