Hello,
Both Worldometer and the Johns Hopkins University have persistently maintained incorrect counts for some countries. This leads a lot of users to either update our tables to the wrong counts (ignoring our cited sources) or repeatedly ask for updates in our talk pages.
I created a summary of common errors here: https://en.wikipedia.org/wiki/Wikipedia:WikiProject_COVID-19/Case_Count_Task...
France, New Zealand and Canada are countries were these errors are persistent and never corrected. I would like to expand on the case for France, which presents the worst error (quantitatively):
* Some overseas territories are double-counted in France total. Overseas departments, as well as the collectivities of Saint Barthélemy and Saint Martin are included in France official totals. Only the collectivities of French Polynesia, New Caledonia, Saint Pierre and Miquelon and Wallis and Futuna are not included. JHU double counts the former.
* Official France already counts include cases at nursing homes (EHPAD), but Worldometer and JHU adds them to the total, effectively double-counting them. The World Health Organization Situation Reports match this official count, not JHU's or Worldometer's.
I have contacted JHU with no response so far. Do you think it would be possible to approach them and ask about this? Unless me and other editors got something completely wrong, JHU and Worldometer figures for France are incorrectly inflated by ~30k cases.
Best,
Mario Gómez
