user20115: Or is it more complicated than that? i.e random?

user16323: The suttas describe beings reappearing in different realms, according to their actions, ie kamma. Skillful actions are said to lead to rebirth in a "higher" realm, and vice versa.

user11241: The Buddha connects rebirth with morality. Right view and shining morality leads to the heavens. Wrong view and hellish conduct leads to the hells.
It is a little bit difficult to translate the Buddhist term "hell-dweller" as "demon." They are not quite the same as "demons" which we know from Judeo-Christian folklore.

user2282: While it's certainly a bit more complicated that that, it definitely doesn't happen randomly. Refer to the 31 Planes of Existence. Notice the 3rd column on each table for each realm lists the various causes that lead to rebirth into that particular realm. It also provided backup sutta references.
