I don't know much about the licencing but I find it slightly odd that
Wikipedia can distribute its contents under a CC-BY-SA licene when it
contains information that is under a more restrictive licence. How am I
supposed to know that population numbers are not covered by the
CC-BY-SA licence?

I don't want to start a huge discussion here about the legal issues of
using the population numbers. I'm just curious to learn why Crown
Copyrighted data can be in Wikipedia.
