Vor V Zakone is predominantly a South Caucasus thing. The number of Georgian vors is disproportionate - and within the Georgian vor world the number of vors coming from the Svaneti region is even more disproportionate. Other vors predominantly hail from Azerbaijan and Armenia and there's a comparatively huge number of Yezidi Kurdish vors from Armenia and Georgia as well.

That doesn't really mean that the Slavs are a minority in the "Russian" criminal world. Most "bratvas" from Moscow, Saint Petersburg, the Urals, Vladivostok, etc...are predominantly ethnically Russian (Slavic) - they also have plenty of Jewish members - and hold a lot of power.

Criminal groups from the North Caucasus - usually Chechen, Ingush and Dagestani (mostly Avar-speaking) groups - are like the Slavic bratvas in that they usually don't follow the vor authority either. Although there seems to be an increase of vor recruitment among North Caucasians.
