It wasn't a criticism, of course something like this is limited by the data available and that's no the fault of the author. I was just musing on what might be a side effect of using what's available.
There wouldn't be a 'total complete and true set' of data for this task, since not all countries use wiki's to the same extent, and languages don't actually delineate between country (eg: Spanish wikipedia is not exclusively the view of people from Spain, nor is English wikipedia exclusively the views of people from England).
