Yes, 'Families' are a fairly foundational artifact of the '3rd space' concept.
It's a bit of a sensitive social issue which relates to 'someone at home', obviously almost always the mother. I have no doubt whatsoever that women having the chance to work, contribute etc. is very material progress, at the same time, I have no doubt that 'homemakers' add tremendous value. The former we measure in terms of productivity, GDP etc. the later, again, it's 'externalized' from our data and language, and kind of 'shamed' a bit in some circles so we just don't talk about it.
In 2022 I kind of just assume the world is fairly gender-less in most respects so I'm always shocked to see this kind of data which shows substantial numbers of women (relative to men) preferring to stay at home. It's still about 50% [1]. I've seen other, more nuanced data that puts it a bit more subtly: men mostly prefer to work full time (but definitely not all), women substantially prefer to work part time with almost equal cohorts wanting full time work vs. stay at home full time. I think the 'part time' concept rings interesting, because it may feel aspirational or 'best of both worlds' for at least some people (men included) who kind of want to spend time with young children, but not be 'locked in the home'.
And finally, we are living a lot longer and so ratio of families with children is smaller, which affects the numbers.
