The inducks database is great for lots of things. But one disadvantage with using the database for statistics is that it doesn't have any category standards you can use to filter the search (the ones added are different from country to country). Ex. if someone index 300+ issues of a daily newspaper for 2019, that would ruin the statistics as you probably don't want those counted among comic books. Also there are fanzines, books about comics etc. – and for Greece especially, there's a large number of children's books that have nothing at all to do with comics added. I would have been nice to have all of those filtered away in a search.
I didn't know the Greeks indexed many children books. The "page layout" for illustrated stories and for a true comic story are normally distinct in the database. We have "t" for text (possibly with some illustrations) or "i" for illustrations (possibly with some text), whereas we use 1, 2, 3... for stories (this is the number of rows of panels per page). Panels without balloons (typically with text beneath the drawings) are indexed like normal comic-book stories. So in theory, it should be possible to filter out publications without "true" stories. One may also count the total number of pages of comics published, instead of the number of publications, as a criterion. I will not do it here, but it is certainly possible.
