The data here is for the underlying indicators that feed into the Welsh Index of Multiple Deprivation (WIMD). WIMD is the Welsh Government's official measure of relative deprivation for small areas in Wales. It is designed to identify small areas where there are the highest concentrations of several different types of deprivation. The full index is only updated every 4 to 5 years but many of the indicators are updated in the interim period and some are updated annually. All indicators are available down to Lower Super Output Area level. This is a geography that is built from census data - it aims to outline small areas with a population between 1,000 and 3,000 people.
