Social renters14.9% · 6,039 households

Household composition

A broad view of household types in this constituency. Project Open Gov uses the four broad groups supplied by the Commons Library so the presentation remains consistent across the UK.

40,462 householdsCensus 2021
One-person households29.1% · 11,791 households
Families with dependent children25.3% · 10,234 households
Other single-family households42.7% · 17,294 households
Other household types2.8% · 1,143 households

Household-composition figures come from the Commons Library constituency dataset. The source uses census data and Project Open Gov displays its broad household groups rather than attempting to harmonise the detailed categories itself. View household-composition source ↗

Disability and day-to-day activities

The source records whether day-to-day activities are limited and uses separate person-level tables for England & Wales, Scotland and Northern Ireland.

93,192 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot6.7% · 6,222 people
Day-to-day activities limited a little11.3% · 10,494 people
Not disabled under the Equality Act82.1% · 76,476 people

Comparison note: the workbook uses different source terminology across the UK: England & Wales uses “Disabled under the Equality Act”, while Scotland and Northern Ireland use “Disabled” / “Non-disabled”. Project Open Gov therefore preserves the source categories and does not present them as one single like-for-like UK legal definition.

Disability figures come from the Commons Library constituency workbook. This profile uses the person-level tables only; the workbook also contains separate household-level disability tables which are not used here. View disability source ↗
