Overview
- Summary of dataset and variables
The Welsh Index of Multiple Deprivation (WIMD) is the official measure of relative deprivation for small areas in Wales, ranking all 1,917 Lower Layer Super Output Areas (LSOAs) from most (rank 1) to least (rank 1,917) deprived. It combines 54 indicators grouped under 8 domains which have the following weights in the overall index: Income (22%), Employment (20%), Health (15%), Education (14%), Access to Services (10%), Housing (9%), Community Safety (5%), and Physical Environment (5%).
WIMD produces domain ranks and an overall index to identify areas with the highest concentrations of multiple types of deprivation. Most of the indicator values, some sub-indicator values and some sub-domain ranks are also published on StatsWales. Please see the WIMD guidance report and technical report for more information.
This table contains data for the 7 indicators that form the health domain. All indicators are rounded to one decimal place.
Local authority indicator estimates have been produced where the original data allows for aggregating to geographies above LSOA level. Where this is not possible for a given indicator, local authority data entries will display [x] in the Data column.
- Data collection or calculation
The purpose of this domain is to measure lack of good health in all people, and to capture predictors of future health based on deprivation experienced in childhood.
The health domain contains indicators of:
percentage of low birth weight (live single births less than 2.5kg), 2015 to 2024 (ONS)
percentage of children aged 4 to 5 living with obesity, 5 years combined: 2016/17 (September 2016 to August 2017), 2017/18, 2018/19, 2022/23 and 2023/24 (Public Health Wales) – indicator data is not published for this (as explained in the technical report)
rate per 100 of chronic conditions diagnosed by GPs, July 2025 (Digital Health and Care Wales)
rate per 100 of mental health conditions diagnosed by GPs, July 2025 (Digital Health and Care Wales)
rate per 100 of cancer incidence, all malignancies excluding non-melanoma skin cancer, 2012 to 2021 (Public Health Wales)
rate per 100 of premature deaths (death under the age of 75), 2015 to 2024 (ONS)
rate per 100,000 of self-reported limiting long-term illness, 2021 (ONS, Census 2021)
- Statistical quality
The WIMD 2025 data have been produced by professional statisticians using the latest data, rigorous analytical methods, and independent validation at every stage. WIMD 2025 builds on previous versions to ensure accuracy and reliability, combining 54 indicators from diverse sources (some but not all are based on official statistics sources) to minimize bias and strengthen robustness. Quality assurance included multiple checks, replication of results, and expert review with domain specialists and local authorities.
An indirect age-sex standardisation process was applied to 5 of the indicators, in order to adjust for different age and sex distributions amongst small area populations.
The data for each indicator has been investigated to assess the impact of the Covid-19 pandemic on trends and data quality.
The pandemic disrupted the data for one indicator, children living with obesity, which means that no data is available for Wales as a whole for 2019/20 to 2021/22.
Limiting long term illness was self-reported during March 2021, just over a year since the pandemic was declared. However data was found to be well correlated with Census 2011 trends used in WIMD 2019.
Two other indicators, cancer incidence and premature deaths, have ten year rolling timespans extending beyond the early phase of the pandemic (ending in 2021 and 2024 respectively). Some longer-term effects of the COVID pandemic are likely to be present in the data (albeit combined with a longer run of pre-pandemic data).
