I put Recensement du ménage n° NNN (=> Household no. NNN census)
As the census is a place event, the house of household no. NNN of such and such a municipality, I will attach it primarily to the place if I could, then join it to the members of the different families, hence my choice to remain in a logic of household in a place
And about the PR (I didn’t really understand its context, why this topic), I use the Forms gramplet to enter censuses and indeed, the Occupation information is often present there. Personally, rather than searching both in the profession events and in a Occupation attribute, it seems to me preferable to use an event filter for the Occupation event and a filter of the attributes of the reference to the census event (if such a filter existed - I developed it with SuperTool) for this Occupation information in the census event. But as I said, I don’t see what the context is so maybe my answer is not the appropriate one
