Find national datasets for United Kingdom

Citymirror helps people and AI agents find where United Kingdom datasets are available — national open-data portals, statistics offices, mapping agencies and sector publishers. The UK has a mature open-data landscape: a national portal (data.gov.uk), a statistics office (ONS), a national mapping agency (Ordnance Survey) and strong sector publishers for transport, environment and planning. Coverage is deepest at national and combined-authority level; city-level real-time feeds vary.
