Source & methodology
Multpl, using Robert Shiller’s historical data. The newest point is the source’s current estimate; older points are monthly observations.

Updates are checked on weekdays. A failed or malformed source keeps the previous dataset and its dates. Monthly history is replaced together so revisions and inflation rebasing remain internally consistent. No values are invented for missing dates.
