The stats by education level are surprising given the increasing difficulty of survival on a single income without roommates. I'm left to gather that marriage as an institution is losing popularity, with informal (to the government) long-term partnerships conferring sufficient desired benefits.

I'm surprised it is that high.

Almost past the 4 oh, and consider the institution of marriage in a legal sense, an outdated scam of misogynistic patriarchal nonsense. I know there are a broad spectrum of roles, not just CIS, and it has to do with inheritance/benefits/property/etc. Don't catfish my stereotype that has obvious exceptions. All I'm saying is that I feel like the system has a misogynistic patriarchal asymmetrical prejudice built in. I am not interested in the type of asymmetric role I was raised to accept in a religious extremest culture. In my personal situation, this would be a disadvantage, but still, I have no interest in an asymmetric relationship of any kind. IMO, marriage is like a will that is only useful in old age.

I am one. AMA

Probably directly proportional to religion falling out of favor.
