If you are indeed interested in pageviews, the definition you linked to talks about the data internally available.
Oh!
Can I ask you to elaborate a bit more on why you need per-country data?
Well, First I've been looking for the most useful tools and sources available (and found very interesting many of them[1]). Second, in this precise case we are running a pilot project in which has been published some academic project results as Wikivoyage itineraries (3 in EN and 3 in ES). These are the articles we are interested in tracking now.
About the rationale, one of the bigger drivers nowadays is the well known link between heritage, tourism and sustainability (example: the Sustainable Development Goals), so there is a trend to better analyze this context to study and plan. Usually touristic destinations have very well defined countries of origin. The best you know the origin, the best you can plan. Also there should be another positive impact in Wikimedia: new incentives for institutions to create or translate articles to the relevant languages. Always restrited to the heritage domain. Here in Spain tourism is one of the main economic sectors and anything providing intelligence would help for better planning and conservation.
Also, we have identified a new potential activity area about doing intelligence analysis of trends in heritage (interest of the public, changes in institutional focuses, new relevant practices, etc), not only about the Spanish one but worldwide. This is also an scientific institution and would find it very useful to collect the most precise traces available (with absolute respect to the users privacy) to look for signals they could use to refocus/prioritize their institutional goals.
So, this is it.
