Number of academics in various EU countries
The data is roughly accurate for France. The French ministry's HR department releases data periodically, and one of the latest report (2017-2018) is available there: http://cache.media.enseignementsup-recherche.gouv.fr/file/statistiques/62/3/Note_NP_2017_2018_1146623.pdf

In summary, in 2018, there were 81,563 teachers in French public universities. This includes 62,491 permanent positions (full professors, lecturers, and full-time tenured teachers), and 19,072 non-permanent. Of these, 7110 are PhD students with teaching duties, and 4500 are "ATER" (a kind of "postdoc", it's complicated). Depending on how you want to count what, the 80k figure is probably overestimated if you exclude PhD students and postdocs, but it's in the ballpark.
