I've been a lot of places and seen a lot of things and I'll give my, admittedly anecdotal, assessment of the places I've been that I think are either undercounted or overcounted.
>United States: Under
>Canada: Over
>Mexico: Over
>UK: about right
>France: Under
>Germany: Under
>Italy: Under
>Spain: Under
>Austria/Hungary: about right
(basically everywhere in mainland Europe I've been has felt under counted)
>Caribbean as a whole: about right
>Costa Rica: over
>Brazil: Under
>Argentina: about right
>South America as a whole: about right actually because I think many are over
>Australia: weirdly over counted
>Phillippines/Malaysia/Thailand/Vietnam: way under
>China: way over
>Japan: about right
>South Korea: over
>India: strangely felt about right, but didn't venture outside city much and simply don't want to/can't imagine there being more because it'd be hell on earth
>Middle East as a whole (minus North Africa): over
>Africa as a whole: way way under
