The data behind the barometers, open.
Every number the barometers publish is computed from official open records, and these are the aggregates themselves, downloadable under CC BY 4.0 with the methodology beside them. Aggregates only, never the contract-level register, which stays at its official source. Cite them with a link to this page or the barometer that reads them.
