where in the world is pipe smoking most common?

Anyone have any thoughts, guesses, ideas? I was looking over the pipes I own and where they're made: Italy, Greece, Ireland, England, France, and Denmark... Quite a variety. Got me to wondering about this.

Is there any part of the world where pipe smoking is relatively common? Like you'd walk down a street and see someone smoking a pipe? Since I got on the pipe slope back around September I have been keeping my eyes open and haven't seen a single person smoking a pipe (aside from at the smoke shop, or friends of mine).

Thoughts?
