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%). \r\n \r\nWIMD 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]( https://www.gov.wales/welsh-index-multiple-deprivation-2025-series#Backgroundinformation) for more information.\r\n\r\nThis table contains data for the 9 indicators which form the community safety domain. All indicators are rounded to 2 decimal places.\r\n\r\nThe data in this table is based on administrative data. \r\n\r\nIndicator data are suppressed if there were fewer than 5 incidents.\r\n \r\nLocal 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.","collection":"The purpose of this domain is to measure the proportion of people experiencing deprivation relating to living in a safe community. It covers actual experience of crime and fire, as well as perceptions of safety whilst out and about in the local area.

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.\r\n\r\nData on recorded crimes and anti-social behaviour were collected and processed by deprivation.org on our behalf, using a method aligned with the English indices of deprivation 2025. Further details on the methodology can be found in the [English indices of deprivation 2025 technical report (MHCLG)]( https://www.gov.uk/government/publications/english-indices-of-deprivation-2025-technical-report). \r\nThe domain uses geocoded microdata on police recorded crime and anti-social behaviour incidents, sourced from the Home Office Data Hub, Police.uk raw data, and bespoke police force extracts. Unlike anonymised public data, these datasets include full location details, enabling precise mapping. Due to sensitivity, all data processing occurred in secure police environments under National Police Chiefs’ Council (NPCC) agreements.\r\n\r\nIndividual crime and anti-social behaviour records were aggregated to LSOAs using a bespoke mapping tool. Crimes within 10 metres of boundaries were apportioned across adjacent LSOAs, replacing the previous 100m buffer used in 2019 to reflect improved geocoding accuracy. \r\n\r\nQuality assurance included checks against aggregate police statistics and removal of anomalies, such as records outside force boundaries. Counts were constrained to police force area totals to address unmapped records and avoid distortions from crimes geocoded to police premises.\r\n","rounding_description":"","reason":"Minor formatting changes"}],"rounding_applied":false,"update_frequency":{"update_type":"none"},"designation":"accredited","related_links":[{"id":"aXiKg","url":"https://www.gov.wales/welsh-index-multiple-deprivation-2025-series","created_at":"2025-11-25T12:56:16.508Z","label_en":"Welsh Index of Multiple Deprivation","label_cy":"Welsh Index of Multiple Deprivation"},{"id":"ZJSjv","url":"https://www.llyw.cymru/mynegai-amddifadedd-lluosog-cymru-2025-cyfres","created_at":"2025-11-25T13:00:06.993Z","label_en":"Mynegai Amddifadedd Lluosog Cymru","label_cy":"Mynegai Amddifadedd Lluosog Cymru"}],"providers":[{"id":"5c2c9994-47ef-4a5b-9c68-9de297ede978","group_id":"b3e4e9b8-86b1-4027-80a2-0e529cff9d54","revision_id":"afd50399-96e6-4712-823d-6fdf93154217","language":"cy-gb","provider_id":"199a8a45-09e0-40f0-8499-245e852cc9d0","provider_name":"Weinyddiaeth Gyfiawnder","source_id":null,"created_at":"2026-02-09T12:40:25.805Z"},{"id":"ff398606-f07a-43bf-b30c-4e754446e938","group_id":"b3e4e9b8-86b1-4027-80a2-0e529cff9d54","revision_id":"afd50399-96e6-4712-823d-6fdf93154217","language":"en-gb","provider_id":"199a8a45-09e0-40f0-8499-245e852cc9d0","provider_name":"Ministry of Justice","source_id":null,"created_at":"2026-02-09T12:40:25.805Z"},{"id":"e35d221c-2378-4a4c-989f-3650bd256623","group_id":"638a25b1-aed1-4825-9ce4-918776b8a764","revision_id":"afd50399-96e6-4712-823d-6fdf93154217","language":"cy-gb","provider_id":"a5e3097c-a031-45fe-adfd-975d49dc5bed","provider_name":"Swyddfa Gartref","source_id":null,"created_at":"2026-02-09T12:40:25.805Z"},{"id":"ed06d147-5dd4-4853-af86-61b91d5fb4c8","group_id":"638a25b1-aed1-4825-9ce4-918776b8a764","revision_id":"afd50399-96e6-4712-823d-6fdf93154217","language":"en-gb","provider_id":"a5e3097c-a031-45fe-adfd-975d49dc5bed","provider_name":"Home Office","source_id":null,"created_at":"2026-02-09T12:40:25.805Z"},{"id":"2022e25b-80d8-4866-b531-203bd9eb4df6","group_id":"b9b1739b-bd23-499f-884d-177df550d867","revision_id":"afd50399-96e6-4712-823d-6fdf93154217","language":"en-gb","provider_id":"d3620b5d-be93-44f7-9289-fe3bf50e78f3","provider_name":"Office for National Statistics (ONS)","source_id":"8796a1a8-37bd-4ae2-ac71-38155eafe373","source_name":"Small Area Population Estimates (SAPE)","created_at":"2026-02-09T12:40:25.805Z"},{"id":"6e20401f-47da-40e9-8d4d-4e439dc75ff4","group_id":"b9b1739b-bd23-499f-884d-177df550d867","revision_id":"afd50399-96e6-4712-823d-6fdf93154217","language":"cy-gb","provider_id":"d3620b5d-be93-44f7-9289-fe3bf50e78f3","provider_name":"Y Swyddfa Ystadegau Gwladol (y SYG)","source_id":"8796a1a8-37bd-4ae2-ac71-38155eafe373","source_name":"Amcangyfrifon poblogaeth ardaloedd bychain (SAPE)","created_at":"2026-02-09T12:40:25.805Z"}],"topics":[{"id":86,"path":"86","name_en":"Poverty","name_cy":"Tlodi"},{"id":88,"path":"86.88","name_en":"Deprivation","name_cy":"Amddifadedd"}]},"publisher":{"group":{"id":"e50c0a08-0474-4cc3-b8a1-eea48a0046b5","name":"Social Justice","email":"statsinclusion@gov.wales"},"organisation":{"id":"4ef4facf-c488-4837-a65b-e66d4b525965","name":"Welsh Government"}}}
