a factor of four seems like a large disparity between this data and the audience panel numbers.>Wouldn't our numbers reflect all unique devices access Hungarian wikipedia from across the globe and not just Hungary? I just ran some queries internally(where we have >country breakdowns) and found that ~1.38 million unique devices accessing hu.wikipedia in the month of March '16 come from outside Hungary.
Correct, the traffic (in terms of devices) is spread across the globe. A pretty sizable portion of traffic (in terms of devices) for Spanish Wikipedia comes from Brazil, Italy, France and Canada for example.
