Local context

About this constituency

Great Grimsby and Cleethorpes brings together the adjoining North East Lincolnshire towns of Grimsby and Cleethorpes. Grimsby is the larger commercial and former fishing-port centre, while Cleethorpes forms a distinct seaside town along the Humber and North Sea coast. The constituency is predominantly urban and suburban, with residential neighbourhoods and local centres forming a largely continuous built-up area. Docks, industrial land and transport infrastructure remain prominent around Grimsby, while the eastern side has a stronger coastal and resort character. The Humber estuary and coastline define much of the northern and eastern edge, giving the seat a clear maritime identity.

Home ownership and renting

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

48,227 householdsCensus 2021
Home owners56.9% · 27,446 households
Private renters27.2% · 13,101 households
Social renters15.4% · 7,412 households
Other tenure0.6% · 268 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.

48,227 householdsCensus 2021
One-person households34.5% · 16,622 households
Families with dependent children27.6% · 13,294 households
Other single-family households34.5% · 16,659 households
Other household types3.4% · 1,652 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.

107,433 people in the source baseCensus 2021Source comparison: England & Wales
Day-to-day activities limited a lot9.7% · 10,436 people
Day-to-day activities limited a little11.6% · 12,429 people
Not disabled under the Equality Act78.7% · 84,568 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 ↗
