This is not a complaint or meant to be disparaging of non-USA places, more of a curiosity. Is there a reason why the United States, with a population of 320+ million, is divided into five regions, while places like Australia and Canada (with slightly less than and more than 10% of the USA's population, respectively), are divided into two or three times as many regions?If I were to take a stab at this, I'd reckon that they just carved up the US in a generic manner that those of us in the US already do.
Is there a reason? Is it just because there isn't a convenient grouping for the territories/provinces/states of those countries?
AFAIK, changing this system may wreak some havoc.
I for one feel it's pointless to have Hawaii and west coast when an ocean separates them, while west coast and Alaska... all part of the same "West region" when there's a country between them. THe proximity is WAAY off. However, with appropriate subject titles, it still works.
