Southampton Itchen covers the eastern side of Southampton and includes neighbourhoods extending from the city centre and waterfront toward the River Itchen and eastern suburbs. The constituency is strongly urban, with dense residential areas, commercial districts, docks and major transport infrastructure. The River Itchen is a defining physical feature and separates parts of the city while being crossed by important road links. Southampton’s maritime and port economy strongly influences the southern part of the seat. Parks and open spaces provide some relief from continuous development. Overall, the constituency forms a major eastern sector of one compact south-coast city.
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.
46,716 householdsCensus 2021
One-person households33.4% · 15,612 households
Families with dependent children27.2% · 12,693 households
Other single-family households32.9% · 15,376 households
Other household types6.5% · 3,035 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.
110,063 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot7.4% · 8,148 people
Day-to-day activities limited a little10.9% · 12,018 people
Not disabled under the Equality Act81.7% · 89,897 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 ↗
