In England: the Index of Multiple Deprivation 2025 decile and rank (of 33,755 neighbourhoods) and the seven domain deciles, from income and employment to crime and living environment; the flood zone; any conservation area; and whether it's in the green belt. Your own columns stay in the download. ## Where the data comes from Councils, wards, parishes, constituencies and LSOAs from the ONS Postcode Directory (via postcodes.io). Deprivation from the English Indices of Deprivation 2025, published by the Ministry of Housing, Communities and Local Government. Flood zones from the Environment Agency's Flood Map for Planning, conservation areas and green belt from planning.data.gov.uk. All under the Open Government Licence. Deprivation is England only: Wales and Scotland publish their own indices. A full address's areas come from its nearest postcode, which can sit across a ward boundary on a street that is the boundary. ## FAQs How do I find the ward and constituency for a list of postcodes? Paste the postcodes above, one per line, or upload your spreadsheet. Every row comes back with its council, ward and constituency as new columns. What is a deprivation decile? England's 33,755 small neighbourhoods (LSOAs) are ranked from most to least deprived on the Index of Multiple Deprivation, then split into ten equal groups. Decile 1 is the most deprived 10%, decile 10 the least. Which constituency boundaries does it use? The 2024 parliamentary constituencies, the ones used at the 2024 general election. Can I paste addresses instead of postcodes? Yes. A full address is placed on the map first, and its areas come from the nearest postcode. How many postcodes can I look up? Up to 5,000 per list. The first 25 show straight away; enter a work email to look up the rest and download the whole file. Do you keep my list? Your postcodes are used to run the lookup. They aren't shared or sold. 1.
