How many inhabitants has Anctartica today (year 2012, Solomani calendar)? I'd say it has no inhabitants as such, and yet there are people living there, mostly rotating in several scientific (or other) bases.
I did a Google Search for "How many people live in Antarctica?" And got 1000-4000, depending on time of year.
So, in my mind, that means that Antarctica, were it a system, would have a pop digit of 3. It doesn't matter that people only live there a few months out of the year-- it matters just that people live there. And, if I were an adventurer or trader, those people would need fuel and food and replacement parts, and maybe could sell me oil or scientific datachips or fish, and maybe, while I'm docked there, I get word that a distant research post has gone silent, and they need someone to go investigate... and there's a shapeshifting alien that looks like Kurt Russell...
To my mind, a population digit of 0 means just that. If we get off the ship in a Pop 0 world, there's nobody else around-- well, okay, up to 9 people can be there. Ruins, sure. Non-sophont flora and fauna, sure. A class X or E starport? Sure, I buy that.
Now, I also don't think that if our crew of 12 lands on a Pop 0 world, suddenly the Pop digit changes to 1. That's because the adventuring crew isn't planning on staying for any appreciable amount of time, unlike people who might be working 6 month shifts on a refinery or at a starport. I know that "appreciable" is sort of vague, but Travellers live in the ship, not on the planet.
This is a good discussion, BTW. It's good to hammer out the nuances of meaning in the absence of clear rules.
