I think this is actually a place where 'identifies as' is legitimate.
When people ask what I do, I would say that I'm a computer programmer (assuming a non tech - if tech I would be more specific). In actual fact, I'm a darn site more senior than that - CTO/Consultant/Architect over the past few years, but if asked, 'programmer' is what comes to mind.
Some younger, american, redditors were scandalised that 'mother' and 'wife' (well, partner) didn't come even in the top 5 things I'd use to describe myself if asked, but, it's true, I would assume someone was asking about me, not my relation to other people (whether I grew them or not)
I converted to freelance when I had the kids, so I always described myself as at least a freelance programmer, not housewife/homemaker, even when, TBH, I was doing very little paid work, but it absolutely is a thing. I spend a good 50% of my 'working' day doing washing, filling the dishwasher, dealing with kids directly (pickups, feeding, spending time with), dealing with kids indirectly (eg. arranging appointments, sorting their stuff), cleaning, paperwork, car stuff, garden stuff etc. I've looked at outsourcing some - cleaner, washing (I don't even iron) gardener, personal assistant for everything, taxis - and the amount of money saved by me doing these tasks makes up for any loss of hourly billing (and I bill a lot!).
It's definitely an occupation.
