Welsh Index of Multiple Deprivation

The Welsh Index of Multiple Deprivation (WIMD) is the Welsh Government’s official measure of relative deprivation for small areas in Wales. It identifies areas with the highest concentrations of several different types of deprivation. WIMD ranks all small areas in Wales from 1 (most deprived) to 1,909 (least deprived). It is a National Statistic produced by statisticians at the Welsh Government. Small areas are Census geographies called Lower-layer Super Output Areas (LSOAs).

The full index is updated every 4 to 5 years. The most recent index was published in 2019. WIMD 2019 index and domain ranks can be seen on the WIMD 2019 tab.

There are numerous indicators that feed into WIMD. Some of these are updated annually (when possible), some periodically, some only for the overall WIMD update and some only when census data becomes available. You can access all the indicator data at various geography levels on the indicator data tab.

You can find more information about WIMD on the webpages on the Welsh Government website (please see the links below).

For those interested specifically in pan-England and Wales measures of local area deprivation, please see the output 'Indices of Deprivation 2019: income and employment domains combined for England and Wales' (under links below).

Geospatial information on WIMD 2019 and WIMD 2014, including shapefiles, can be found on Data Map Wales (see link below).
