Is there a way to know how many people use Wikipedia
per interface language?
No.
Said in other words, I want to know how many people
display the Wikimedia project interface in the different version of German and
Alemannisch.
Until
https://phabricator.wikimedia.org/T58464 is fixed (hopefully in
this decade), the requests with non-default language are negligible.*
What makes you think that you need such a level of precision and
https://stats.wikimedia.org/EN/TablesPageViewsMonthlyCombined.htm is not
enough?
Once the use case for such precise numbers is clarified, probably we can
extract exact data with a method similar to
https://phabricator.wikimedia.org/T65416 after it's fixed (hopefully
this year; the bug has made localisation and new subdomain requests
practically impossible or unfeasible in dozens languages, for many
months now).
Nemo
(*) Even considering the sum of requests with uselang parameter** and of
registered users with a non-default language choice in preferences.
(**) Even in Commons, despite all the uselang-specific incoming links
and the language selection gadget.
