Local context

About this constituency

Mid Sussex covers a broad area of central West Sussex and includes towns such as Haywards Heath and Burgess Hill together with surrounding villages and countryside. The two main towns provide the largest concentrations of population, with strong rail links toward London and Brighton. Outside them, settlement becomes more dispersed across the Weald, with farmland, woodland and smaller communities separating built-up areas. The South Downs influence the southern edge, while the High Weald lies farther north and east. The constituency therefore combines growing commuter towns with a substantial rural hinterland and sits between the larger urban centres of Brighton, Crawley and the south coast.

Home ownership and renting

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

40,896 householdsCensus 2021
Home owners71.9% · 29,409 households
Private renters15.3% · 6,262 households
Social renters11.4% · 4,650 households
Other tenure1.4% · 575 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.

40,895 householdsCensus 2021
One-person households27.7% · 11,333 households
Families with dependent children30.8% · 12,594 households
Other single-family households38.2% · 15,612 households
Other household types3.3% · 1,356 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.

98,398 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot5.3% · 5,207 people
Day-to-day activities limited a little9.4% · 9,239 people
Not disabled under the Equality Act85.3% · 83,952 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 ↗
