Agree op is wrong as worded. Sort of depends how you count though. If you count like an anthropologist, tons of non patriarchal examples.

But they don't seem to have scaled in the same way for one reason or another.

If you count by membership the number of people who live in patriarchal societies vs not, I think you would come up with an answer very very close to 100% patriarchal.

There's a little bit of an interesting facet of this, which is that it depends on how you're defining patriarchal societies - if you're looking at what is explicitly encoded into the legal systems, it's hard to argue that, as of today, the US or really most of modern world qualifies, and similarly if you're looking at who holds power, while the gender skew is still towards males, a disinterested observer from the future would not observe a society in which power is either exclusively or as a rule held by men. I'm not sure the legal structures around gender in China or India (if we're talking about percentages of the global population), though, although at least for India one could argue Indira Gandhi might have been the most powerful person in India since the empire.

Culturally is a different question, obviously.
