Currently we have an amazing tool which every month determine what pages are most viewed for a Wikiproject and then provides a sum of the pageviews for all articles within that project. An example of the output for WikiProject Medicine in English.
The problems is that this tool only exists in English and is running on toolserver rather than Wikimedia Labs. So while we know what people are looking at in English, and this helps editors determine what articles to work on, other languages do not have this ability.
Additionally we are do not know if the topics people look up in English are the same as those they look up in other languages. In the subject area of medicine this could be the basis of a great academic paper and I would be happy to share authorship with those who help to build these tools.
A couple of steps are needed to solve this problem:
For each article within a Wikiproject in English, take the interlanguage links stored at wikidata, and tag the corresponding article in the target language Figure out how to get Mr. Z's tool to work in other languages https://en.wikipedia.org/wiki/User_talk:Mr.Z-man#Popular_pages_-_please_can_you_make_an_exception.3F . He supposedly is working on it and I am not entire clear if he is willing to have help. Another tool that could potentially be adapted to generate the data is already on Labs http://tools.wmflabs.org/glamtools/treeviews/
