Heh, I need to finish that guide...it's incomplete atm, and only documents planets with city lights.
It's simple enough; find a temperate world in highsec and fly to its darkside, see if it has city lights. Even if it doesn't, it likely has a very sparse population smaller than a billion.
The Federation is an interesting case. Seyllin I was described as being completely subterranean, yet there was a working ecosystem present with flora, skyscrapers and so on (likely a rendered sky as well). Obviously, all of the other empires would have colonies on non-temperate worlds, but "functional" cultures like Minmatar and Caldari would unlikely go as far as to making it all fancy like the Gallente.
