Public data about Wales is scattered across government portals, spreadsheets, and PDFs. This site brings it together at neighbourhood scale so anyone can see what is happening where they live, work, or serve.

Why this exists

Official statistics about Wales are published in good faith but rarely designed for the people they describe. A spreadsheet on StatsWales, a dashboard on the ONS site, a PDF from GOV.WALES. The information is public. It is just not easy to reach.

This platform maps datasets across four geographic levels, from Local Health Boards down to individual LSOAs of roughly 1,500 residents. Every number links back to its original source so you can check it yourself. No guesswork, no generated values.

What it covers

  • Deprivation: Welsh Index of Multiple Deprivation at LSOA level, including all eight domain scores
  • Population: mid year estimates by LSOA, MSOA, and local authority
  • Health: NHS dental patients treated, GP staffing levels, pharmacy items dispensed, and practice staff by health board
  • Housing: median house prices and property sales volumes from HM Land Registry
  • Facts: verified information about each area from Wikipedia and CADW, with direct links to source pages

Data philosophy

Every figure on this site carries a source URL. Nothing is generated or estimated behind the scenes. If a metric has no value for a given area and time period, the map tells you so. Data that cannot be verified does not get published here.
