I mean world of darkness groups in general.
This gets a lot more complicated if you take things like "the umbra" into account. But I will try (Also if you looking for something specific, it's better to ask directly, cause the whole thing is a bit of a clusterfuck and some information's may contradict each other.)
Mage:
You ever heard those conspiracy theories about how there is a secret world government, that is made up out of the richest people on earth, who has future tech, secretly controls the media and also is in contact with Aliens? That the "Technocratic Union", so they control the whole world. So why haven't they won? (Also this is version dependent and M20 gives the storyteller the choice about how much control they really have).
Cause a) Mages can just fuck off to other planes and don't care for physical laws, so they can only own one house in a city, but that is on the inside as big as a block. Also space doesn't matter as much when you can teleport. b) Mage isn't about fighting for terrain it's fighting about concepts, ideas and ideals. So as long as there are people who held to superstitions, faith or simply believe urban legends the Technocratic Union hasn't won yet.
Also the Nephandi have most likely (again it's storyteller digression) secretly infiltrated the TU (and the Traditions) and are now secretly in control. In general they are everywhere (at least if we take the more modern approach by "Book of the Fallen", which is a great book)
The Traditions are difficult to place not only because a lot of their more powerful mages fucked off to some Horizon Realm (which may or may not have been destroyed by the Avatar Storm), but also because how powerful and organized they are is depending on the chronicle and the ST. So they difficult to place, but you can expect them to have at least some kind of influence in the bigger cities.
Okay that was Mage so let get to Werewolf, they are technically easier to pin down, just look at there Caerns and you know where they tend to be, but that said I never really got into Werewolf so I can try to get you some information, but someone else is more likely better qualified. In general Werewolves (and other shapeshifter) are in control of more "rural" areas, so don't expect them to rule cities (even if you can find some of them there).
Asia - Is controlled by the Beast Courts, which hold different kinds of shapeshifters
Africa - Is controlled by the Ahadi
The Wendigo Tribe is in control of Canada and Northern part of the USA (or atleast they say, that they are)
The Ukenta Tribe is in control of areas of native american peoples, so reservoirs and stuff.
The Get of Fenris Tribe is in control of Scandinavia
The Fianna Tribe is in control of Ireland and (parts of) Great Britain
The Silver Fang and the Shadow Lord Tribes both believe they are in control of the "Garou Nation" and with that (almost) all Werewolves...
In general if it's rural or untouched nature you can expect it to be under the control of on the Shapeshifting breeds.
Changelings and Wraith control their own reflection of Earth each, called the Dreaming and the Shadowlands respectively, while they still have influences on the "human world" I wouldn't but them on the same level as the factions there.
Demons, I have no clue. Can't remember if there even is explicit stated which house holds influence where.
