The chips under Built on name the upstream producers each provider aggregates, composites or models — Our World in Data, for instance, is built on V-Dem, the Global Carbon Project, the Energy Institute, UN WPP and FAO. A Primary source chip means the provider collects the data itself.

Only indicators marked redistributable are served, and every provider’s attribution travels with its data — on every page and in every API response. Reused under the terms of each source licence.
