I thank you.
Monaco is considered to be the most densely-populated country on Earth, and a small region of Macau the most densely-populated area on Earth, but the most densely-populated area ever recorded was pulled down about a decade ago (due to overcrowding

). Its population density was a whopping great 1.9m people per square kilometre).
But can anyone tell me in which country it could be found?
EDIT: Sorry. I thought I'd UP's question right.

ops: I really am chucking the etiquette book out the window today.
