Local context

About this constituency

Mitcham and Morden covers the eastern and central parts of the London Borough of Merton. It is centred on the neighbouring communities of Mitcham and Morden and includes extensive residential neighbourhoods, local shopping centres and major transport links. Mitcham has a long-established town centre and large areas of housing, while Morden is strongly associated with its Underground terminus and surrounding suburban development. Parks, commons and playing fields provide significant open space within the constituency, particularly around Mitcham. The seat is predominantly suburban and forms part of continuous south London, but its green spaces and lower-density districts distinguish it from more densely built inner-London constituencies.

Description last reviewed 17 September 2026.

Home ownership and renting

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

44,823 householdsCensus 2021
Home owners53.1% · 23,779 households
Private renters27.0% · 12,111 households
Social renters18.5% · 8,292 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.

44,823 householdsCensus 2021
One-person households23.9% · 10,713 households
Families with dependent children34.9% · 15,646 households
Other single-family households31.3% · 14,041 households
Other household types9.9% · 4,423 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.

123,762 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot5.6% · 6,961 people
Day-to-day activities limited a little7.5% · 9,287 people
Not disabled under the Equality Act86.9% · 107,514 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 ↗
