Note: The article counts listed above are actual counts collected at (approximately) 00:00 UTC on 2020-01-01. All counts are based on what MediaWiki sees as constituting an article (or content page), as reflected at each wiki's Special:Statistics page. Language counts include closed (but not deleted) wikis and count "Simple English" as a separate language when such a wiki exists within a project. The test wiki counts for Beta Wikiversity and the Incubator were checked in the first hour (UTC) of 2020-01-01.

  • The Guianan Creole Wikipedia is open for editing after being created as a standalone wiki earlier today, with content imported from the test wiki at the Wikimedia Incubator; there is no official article count yet, since the wiki's statistics will not be initialized until 1 December.
  • The Shawiya Wiktionary is open for editing after being created as a standalone wiki earlier today, with content imported from the test wiki at the Wikimedia Incubator; there is no official entry count yet, since the wiki's statistics will not be initialized until 1 December. This is the first language to ever have a Wiktionary created as a separate subdomain before the corresponding Wikipedia (which is still a test wiki).

  • The Albanian Wiktionary has reached 10,000 entries.
  • The Yiddish Wiktionary has reached 500 entries.
  • The Thai Wikisource has dropped below 10,000 text units again (currently down to 7,732 text units, a loss of about 38% from its previous count 24 hours earlier), as the wiki continues to experience huge, sudden, "unexplained" changes in its text-unit count (first on August 9th, then when the wiki was recounted on September 15th and today, October 1st).

  • The Serbo-Croatian Wikipedia has reached 10,000 uploaded files.
  • The N'Ko Wikipedia has opened for editing after being created as a standalone wiki, with its content having been imported from the Incubator test wiki (the wiki's statistics have not yet been initialized, so there will not be an official article count until October 1st—but it will probably be somewhere around 200).

  • The Silesian Wikipedia has reached 50,000 articles, as a bot continues to create thousands of articles about fungi; such articles now constitute approximately 85% of the articles on the wiki.
24
  • The Azerbaijani Wikipedia has reached 150,000 articles.
  • The Bavarian Wikipedia has reached 30,000 articles.
  • The Silesian Wikipedia has reached 40,000 articles, as a bot continues to create thousands of articles about fungi; such articles now constitute approximately 80% of the articles on the wiki.
  • The Neapolitan Wikisource has reached 10,000 text units, as the counting method used on the wiki has been changed to count all pages in the content namespaces instead of only those containing a wikilink.

  • The Hindi Wikibooks has reached 500 book modules.
  • The Thai Wikisource has reached 10,000 text units again, after dropping below that level on August 9th; today's increase (not explainable based on observed on-wiki activity and hence apparently almost entirely due to the wiki being recounted) leaves the wiki at almost the same number of text units as it had before the unexplained drop.

  • The Shona Wikipedia has reached 10,000 registered users.
  • The Vietnamese Wikiquote has dropped below 200 content pages (down to 175), apparently because of a template change made to several hundred main-namespace pages (from one that contained a wikilink to one that does not).

  • The Thai Wikiquote has fallen below 500 content pages (a 93% drop from 3,257 one day ago down to 224 now) — this is presumably due to the regularly scheduled recount of all Wikimedia wikis, but the size of the drop is unexpected and currently unexplained. (Upon further research, the current count of 224 text units seems "not unreasonable" based on a random sample of main-namespace pages: only 1 of 30 sampled pages appeared to contain any wikilinks, giving a rough estimate of 0.0333… × 3,326 = 111 content pages. However, it is still not clear how the count remained above 2,000 for more than 2 years before today, and what changed in the last 17 days [since the last recount] to make it drop now.)
  • The Neapolitan Wikisource has fallen below 500 text units after being recounted completely for the first time since content importing was finished.

  • The Wikimania 2018 wiki has been closed (locked to prevent public editing); starting this year all Wikimania events will be served by a single Wikimania wiki, using a different namespace for each year instead of a different wiki (note that pages are still being moved around the wiki to implement this plan).

  • The Macedonian Wikipedia has reached 100,000 articles. (Note that the milestone observed on this day was due to the semimonthly recount of the wiki; a more thorough analysis of page creations, deletions, and edits on the wiki itself reveals that the likely 100,000th article was actually created on 27 April 2019, as was determined by the community.)
