The Indices of Deprivation 2025 (IoD25) and specifically the Index of Multiple Deprivation 2025 (IMD 2025) are a set of official statistics that show how deprived each small neighbourhood (Lower Super Output Areas) in England is compared with others.
They use seven areas of deprivation - income, employment, education, health, crime, barriers to housing and services, and living environment - and combine them to produce the official Index of Multiple Deprivation (IMD 2025). Two related measures focus on income deprivation for children and older people.
You can view the IMD 2025 interactive report, containing interactive maps and tables for Portsmouth’s neighbourhoods (IMD and all seven domains).
IMD 2025 Portsmouth Summary
The Index of Multiple Deprivation 2025 (IMD) ranks all small neighbourhoods in England (LSOAs - about 1,500 people) by how deprived they are compared with each other.
Overall position (IMD average score across neighbourhoods)
Portsmouth has improved since 2019 (after adjusting 2019 figures to today’s boundaries). We rank 64th most deprived out of 296 local authority areas (was 58th) and 51st out of 153 upper‑tier councils (was 46th). (In IMD rankings, 1st = most deprived)
Concentration of deprivation (most deprived neighbourhoods)
This has worsened. Portsmouth is now 41st out of 296 local authority areas (was 45th) and 31st out of 153 upper‑tier councils (was 35th). This measure gives extra weight to the very most deprived neighbourhoods.
Neighbourhoods most affected
15 of Portsmouth’s 125 LSOAs (12%) are among the 10% most deprived in England. Just over half (8) are in Charles Dickens ward; the others are in Paulsgrove (3), Nelson (2), Fratton (1) and St Thomas (1).
