2025 · the most deprived LSOA in Wales on the Welsh Index of Multiple Deprivation
Verified against source, 29 October 2026, 11:47 UTC1,917 small areas on Wales's LSOAs of 2021, too many to chart. Each area's figures are on its council's page, under Small areas, with every other dataset's for the same council; the councils are listed below. The whole file is in the CSV and JSON.
The hub keeps each figure on the area its file gives, never moved onto another year's areas. An area is found under the council the ONS's output area lookups put it in, or for Scotland and Northern Ireland the area register; an LSOA of 2011 that ended in 2021, which no lookup of today holds, under the council its own file names. 1,917 of the 1,917 are under a council with a page.

Notes
- Each LSOA's rank is among Wales's 1,917 LSOAs, 1 being the most deprived, and its decile places it in tenths of them by the Welsh Government's own bands, 1 being the most deprived tenth. LSOAs whose scores tie share a rank. Ranks are relative, within Wales only: they cannot be compared with England's, and the Welsh Government changed the indicators between editions.
- The eight domains are income, employment, health, education, access to services, housing, community safety and the physical environment; the index combines them with the Welsh Government's weights.
