Southampton Test covers the western side of Southampton and includes central and residential neighbourhoods around the River Test and city docks. The constituency is predominantly urban, with housing, commercial districts, university-related areas and port infrastructure closely integrated into the wider city. The River Test and Southampton Water shape the western and southern edges, while major road and rail routes provide links toward the New Forest, Winchester and the wider region. Parks and green spaces are distributed throughout the seat. Overall, the constituency represents the western half of one major south-coast city rather than extending into a large rural hinterland.
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.
45,588 householdsCensus 2021
One-person households33.2% · 15,116 households
Families with dependent children27.7% · 12,616 households
Other single-family households29.8% · 13,598 households
Other household types9.3% · 4,258 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.
110,532 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot7.0% · 7,702 people
Day-to-day activities limited a little10.3% · 11,391 people
Not disabled under the Equality Act82.7% · 91,439 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 ↗
