About Cambria

Cambria is built from open public datasets — Companies House, the Charity Commission, ONS, NOMIS, HESA, HMRC, UKRI, the Welsh Government and others — assembled into a coherent, citable view of the Welsh economy.

Every figure carries a publisher, retrieval date and licence so it can be traced back to its primary source. Datasets that haven't been signed off do not surface as numbers — Cambria reports the gap honestly instead.
