He he.. gotta love the useless city numbers which in fact is just a broken comparison of large municipals...
... In Copenhagen's case we have a "city" inside the Copenhagen municipal city borders called Frederiksberg with 90.000+ people giving us a real spot at 34... but ocause if you look at single municipals only you'll get wierd numbers like that - funny enough they didn't do that with stuff like the City of London which actually have a population of only 9,200

And let's forget all about the metro population despite it being an unbroken urban area... ( add another mil+ to Copenhagen )
Sorry to bitch like that, but the numbers are so far from the real city sizes... and municipal sizes varies greatly in different countries... to put it into perspective to you Yanks it would be like taking the population of Downtown LA and writing that figue for the entire city ( 3,957,875 ) fair or realistic - I think not!
