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.
38,994 householdsCensus 2021
One-person households26.3% · 10,247 households
Families with dependent children33.5% · 13,055 households
Other single-family households36.6% · 14,256 households
Other household types3.7% · 1,436 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.
99,059 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot5.2% · 5,108 people
Day-to-day activities limited a little8.4% · 8,349 people
Not disabled under the Equality Act86.4% · 85,602 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 ↗
