World Uncertainty Monthly

- 64,512 observations from January 2008 through August 2026. - Four monthly indexes (WUI, WTUI, WPUI and WSI) for 71 countries plus GDP-weighted global series. - Direct country coverage for 30/39 modeled authorities; global series are available to every authority. - The current workbooks were published on 2026-09-06. Historical release vintages were not supplied, so all past values remain excluded from strict backtests and are retained for forward use and explicitly labeled research sensitivity tests. - The indexes analyze copyrighted Economist Intelligence Unit reports. Raw and normalized material is restricted to internal research pending a rights review. - No missing-country proxy is fabricated, and the package is isolated from canonical model inputs.
