I would recommend looking at:
https://en.m.wikipedia.org/wiki/Marriageable_age
Then sort the table by gender and with/without parental/judicial consent and you will note that with the exception of straight up theocracies and despotic regimes there isnt a clear pattern on religion.
I think under authoritarian regimes women suffer disproportionately and massively would be a better pattern. We can have a discussion on why islamic majority countries have greater representation on the authoritarian scale but that’s a lot more complex.
For sure. When Muslims are allowed to make the decision, the majority seems to always oppose child marriage.
When you have authoritarians make the decision, they concentrate power in as few people as possible and women always suffer.
I’m what one might call an anarchist (kind of) so maybe we take my opinion with a grain of salt.
