Every number used anywhere on this site, grouped by who published it. The repository is private, so this page and the per-model assumption blocks are how the method stays checkable.
73 figures in total: 43 official, 11 reported, 19 estimates. Official means it comes from the body that produces it — the state, the town, a statute. Reported means a news outlet or a document reported it. Estimate means nobody has published it and I have assumed a value; those carry a note explaining the basis and are the first things to replace.
