You mean states, or some tribes here and there?

Like, you're adding say USA (350M), China (1.4B), France (80M), etc with say, some Amazonian tribe of 5K people (which you don't count as part of the 99.999% patriarchical Brazil)?

I guess in that way it's enough that 200 tribal villages (more than the UN nations iirc) to be matriarchical for the world to be "predominantly matriarchical" or at least 50%-50%.
