sure, for e.g. China or any large-ish country this works, but as soon as population <1 million or so the range would be very wide—e.g. Iceland presumably has some EA presence but it would be strange to put it at the top without knowing the actual data. If I wanted to spend more time on this I think just asking for the raw data would be best (I am unsure if they would give it to me, and I haven’t tried).
