Hey .. it was me!!! Can you not tell?:-P

Basing it 'importance' on the population is a 'guide'.
The actual population may not be known, keeps changing and the population could be based on the area the place services,
not just its local residential area.

It has to be a subjective assessment. And it has to be locally relevant.
