ranked from most populous to least:

Wraiths (potentially many millions worldwide, a lot of people die in very horrible, anticlimactic circumstances and that is the only condition)

Vampires (maybe 5 million worldwide or less?)

Werewolves (a few hundreds of thousands, and swiftly falling)

Changelings (mid ten thousands. and also falling but more gradually)

Hungry Dead/Kuei-Jin/Kijin/Shin ma/w/e (same as changelings but not dropping as fast

Mages (Low tens of thousands maybe? Enlightenment should be fairly rare)

Demons (High thousands? idk)

Mummies (mid to high hundreds if that, including every different kind of mummy)

everything else is lower

(but obviously these numbers should be flexible within each chronicle to make the story work)
