Likelihood to participate in Wikimedia Commons depending on the language of origin. Three groups stood out. Respondents coming from Wikimedia websites in Arabic, Bulgarian, Catalan, Czech, Danish, Finnish, French, Hebrew, Italian, Dutch, Norwegian, Polish, Swedish and Chinese language are correlated with regular participants in Wikimedia Commons. Users from projects in German, Hungarian and Vietnamese language are in a similar but less pronounced situation. On the other hand, respondents originating from a Wikimedia project in English, Japanese, Portuguese, Russian and Turkish language show the opposite correlation: many of them do not participate in Wikimedia Commons. The size of Wikipedia does not seem to be a decisive factor; we suggest that policies and culture on each wiki are, in fact, mostly responsible for these differences.

  • Picture this! Magnus Manske, November 24, 2014: counting the number of items with images on Wikidata and Wikipedia (by default, navigation bar logos and various icons are counted just as actual photographs of the article topic -> crude filter, counting only articles with images (one would do) that were not used in three or more articles in total.) (English Wikipedia failed to return a timely result; and since its generous sprinkling with “fair use” local images would inflate the number anyway, omitting this result here)
