GeoData breakdown
Polimapper has exclusively mapped the new Indices of Deprivation by parliamentary constituency.
The Ministry of Housing, Communities & Local Government has officially released the English Indices of Deprivation (IoD) 2025, which measure various levels of deprivation across small areas in England.
The new iteration of the IoD was calculated across seven distinct domains to produce the overall Index of Multiple Deprivation (IMD). The domains and their weightings are:
- Income deprivation (22.5%)
- Employment deprivation (22.5%)
- Education, skills and training deprivation (13.5%)
- Health deprivation and disability (13.5%)
- Crime (9.3%)
- Barriers to housing and services (9.3%)
- Living environment deprivation (9.3%)
According to the IMD 2025 release, the most deprived neighbourhood in England is located in the Jaywick & St Osyth area of Clacton-on-Sea.
Polimapper’s data team has mapped this Lower Super Output Area (LSOA) decile data to constituency boundaries, allowing for a detailed view of IMD and indicator values for each parliamentary area.
In England, nearly two thirds of parliamentary constituencies have at least one neighbourhood ranked in the most deprived decile. The data shows Birmingham Erdington, Bradford East, and Wolverhampton South East among the 15 constituencies with the highest average deprivation.
Bradford East and Walsall and Bloxwich saw the highest income and education, skills and training deprivation.
Conversely, another 14 constituencies saw the lowest average deprivation levels. This includes Epsom and Ewell, Rushcliffe and York Outer. In England, 75% of constituencies have at least one of the least deprived neighbourhoods.
