Does anyone know how many unique (that is not reproduced
around other languages) articles there are in toto in the
non-English language wikipedias, which do not have a
corresponding English language wikipedia article? Can
even a rough estimate be made?
On the basis of clicking "Zufälliger Artikel" 50 times, it looks to me
like around 50% of deWP articles do not have interwiki to enWP. Only a
small proportion of those without such interwiki look like they should
have a corresponding article in enWP. The proportion with interwiki but
no English interwiki is not huge - say 25%? This is not a very
sophisticated technique from a statistical point of view, but it could
be refined to get a better view by sampling of the overlapping of the
Wikipedias. It all suggests the answer to the question is "around one
million" - not 500000 (too low), not two million (maybe too high?).
Does anyone know the answer to the opposite question? How many
articles on the English Wikipedia lack interwiki links? It is possible
(but less likely) that the articles exist in both places, but haven't
been linked with an interwiki yet. I find examples of that fairly
regularly, but am not sure how common it is.
