Home ownership and renting

Housing tenure shows how households in this constituency described their home at the most recent census.

40,736 householdsCensus 2021
Home owners63.8% · 25,981 households
Private renters19.9% · 8,126 households
Social renters15.3% · 6,224 households
Other tenure1.0% · 405 households

“Other tenure” combines shared ownership and households recorded as living rent free.

Housing-tenure figures come from the most recent census: 2021 in England, Wales and Northern Ireland and 2022 in Scotland. View housing-tenure source ↗

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.

40,734 householdsCensus 2021
One-person households27.3% · 11,118 households
Families with dependent children31.0% · 12,631 households
Other single-family households36.4% · 14,839 households
Other household types5.3% · 2,146 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.

100,133 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot7.3% · 7,322 people
Day-to-day activities limited a little10.3% · 10,293 people
Not disabled under the Equality Act82.4% · 82,518 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 ↗

Our long-term vision is to save Fort Widley's Cold War bunker. Enabling more people to have the opportunity to learn about and engage with this unique heritage asset - a historically significant part of our national civil defence network with a largely intact 1950s Operations Room. This project is an essential step in achieving this ambition. The Feasibility Study will provide the us with a comprehensive understanding of the challenges of opening up the bunker including the barriers to access, options for interpretation and learning, condition of the areas of Fort housing the bunker, condition of the collection, and the financial and organisational impact on our organisation. The Feasibility Study will provide us with an important legacy, providing the information and evidence we need to inform the planning for the implementation of our long-term vision. The findings will feed into and inform the phasing of our development plans.
