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.
43,835 householdsCensus 2021
One-person households28.2% · 12,382 households
Families with dependent children31.5% · 13,803 households
Other single-family households33.7% · 14,754 households
Other household types6.6% · 2,896 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.
113,749 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot5.8% · 6,548 people
Day-to-day activities limited a little9.3% · 10,608 people
Not disabled under the Equality Act84.9% · 96,593 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 ↗

“Seeing Nature, Shaping Culture: Art and Identity in Prehistory”
Celtic Harmony
£229,929
The National Lottery Heritage Fund · Heritage
About this award
Through “Seeing Nature, Shaping Culture: Art and Identity in Prehistory”, Celtic Harmony Camp aims to produce a two-year programme of exhibitions which will intend to deepen public understanding of how nature and cultural exchange shaped life in Prehistoric Britain. Building on 25 years of heritage work, the project will create a new exhibition room in the newly built Prehistory Centre developing a dynamic space hosting museum loans, community-curated displays, and interactive community events. By connecting local artefacts, such as the Hitchin Beaker, to wider European stories of migration, identity, and creativity, we will make complex histories accessible and relevant to today’s audiences. The project seeks to inspire dialogue about cultural diversity and environmental awareness through art, archaeology, and storytelling. Ultimately, it will strengthen Celtic Harmony’s sustainability, expand participation to a wider audience, and celebrate our 25th anniversary with a legacy of inclusion, engagement, and renewed appreciation of Britain’s Prehistoric heritage.
