How often do you create families and households that have multiple sims?

I haven't created any new sims in my world (one save stretching back to February 2020) in ages—it's gotta be close to a year now. I think Super Dave Lembeck was the last one, maybe Steve Garamonde, the former the patriarch of one of the big-deal families, the latter the tortured bartender whose customers sing their problems like Steve's Ryan Stiles.

In every case where I created someone in CAS, it was as one sim whose story I wanted to see unfold in the context of whatever they got up to.
