DataKind UK Open Data Sets
DataKind UK is a charity that connects data scientists with social-good organisations, and this page collects the open datasets it finds useful for that work. The selection leans towards UK public and social data: government statistics, health, crime, housing, and related social themes.
Because the list is shaped around social-impact projects, it is a good filter when you want UK data with real-world relevance rather than a raw dump of every portal. Each entry links to the primary source, so check the licence and update schedule there. Pair it with data.gov.uk and the UK Data Service when you need to go deeper on a specific topic.
