Hemel Hempstead constituency is centred on the Hertfordshire town of Hemel Hempstead and covers most of its main urban area. The town was greatly expanded as a post-war new town, with residential neighbourhoods arranged around a central commercial area and extensive green spaces. The River Gade and Grand Union Canal run through the valley, while housing spreads onto the surrounding higher ground. Major road and rail links connect Hemel Hempstead with London, Watford and the wider Hertfordshire area. The constituency is predominantly urban and suburban, with open countryside appearing mainly around its outer edge. Its planned neighbourhood structure gives the seat a distinct physical character.
Election data comes from UK Parliament. Turnout percentage is calculated by Project Open Gov from Parliament's turnout and electorate figures.

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.
41,842 householdsCensus 2021
One-person households28.1% · 11,778 households
Families with dependent children32.4% · 13,560 households
Other single-family households35.2% · 14,745 households
Other household types4.2% · 1,759 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.
103,296 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot6.4% · 6,635 people
Day-to-day activities limited a little9.6% · 9,951 people
Not disabled under the Equality Act83.9% · 86,710 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 ↗

Safeguarding Frogmore Paper Mill: Urgent Stabilisation and Roof Repairs
The Apsley Paper Trail
£231,500
The National Lottery Heritage Fund · Heritage
About this award
Through this project, The Apsley Paper Trail aims to secure the long-term survival of Frogmore Paper Mill — the world’s oldest mechanised paper mill and birthplace of modern papermaking. The project will enable the Mill to become safe, watertight and resilient against weather conditions so it can once again welcome visitors, volunteers and learners to experience a working industrial heritage site of national significance. Urgent stabilisation and roof repairs will prevent catastrophic loss, protect historic machinery and collections, and create a solid foundation for future conservation and redevelopment. By saving this irreplaceable heritage, we will revitalise Frogmore’s role as a centre for education, skills training, sustainability and community pride. The project is the first step in re-establishing Frogmore as the UK’s leading paper heritage site — a living museum celebrating innovation, craft and the cultural revolution paper inspired.
