Aukrest - there is nothing to guess about that map.
And no it's not about the environment. You shouldn't be confused by the green colour, I just choose a random one.
Is it... provinces that have changed their administrative borders?
Red is something.
Blue is something else.
Purple is both something and something else.
Right?!?!?????
Darker means higher values
Spoiler :The answer is percentage of people who desire US only maps in this thread.
To put it mathematically, the US has a population of ~308.000.000 vs the rest of the world with a population of ~6.612.000.000. That's less than 4.5%.
Please, no more US only maps in this thread.
Red is something.
Blue is something else.
Purple is both something and something else.
