Demographics only in a loose sense - though actual demographics would be interesting too...

I'm interested in a population-level overview of domestic servants, in eras where all well-to-do households had at least some sort of maid, cook or similar - particularly 17th to early 20th centuries. Specifically: roughly what proportion of households had servants? What proportion had more than one or two? (Not very well-defined, since servants don't have to be live-in, I guess.) Obviously it varies, but any examples/generalities welcome.

This is a world-building question rather than specifically GURPS, or even role-playing, but hopefully of some wider interest.

Any good general sources for this kind of information? GURPS supplements would be great, but pointers to academic sources would be good too.

Thanks!
