Can someone suggest another term for “social fact”?

Social facts are things such as institutions, norms and values which exist external to the individual and constrain the individual.

The problem I’m getting is that “fact” means a truth, at least to me. It is a fact that sky (on a clear day) looks blue, it’s a fact that humans love conditionally, it is a fact that murder is a crime in South Africa. But calling the set of rules of law ministry a “social fact” seems quite indigestible. According to the definition I gave above, cremation is not a process but a “social fact”.

Can someone suggest another term for “social fact”? They are calling a church a “social fact”.

I would call such things social constructs and/or customs.

A social construct or construction is the meaning, notion, or connotation placed on an object or event by a society, and adopted by the inhabitants of that society with respect to how they view or deal with the object or event.[6] In that respect, a social construct as an idea would be widely accepted as natural by the society.
