It took me ages to find what you were referencing in [3], but it’s not inflation adjusted, so meaningless. I’ll assume the rest of your citations are equally meaningless.
Also home ownership rates, it’s by owner occupied dwellings, which would include owner occupied duplexes and triplexes. My building is technically owner occupied, he claims the in-law unit and receives mail there. But both flats are rented out.
Percentage of budget is naturally inflation adjusted…
The census owner % methodology is by respondent address. So if those are 3 addresses then that’s 33% owner occupied building. If you are all sharing an address and the landlord is the respondent then its 100% owner occupied. But importantly the methodology has been largely the same across measurement periods back to the 70s.
It gets harder before that because the census didn’t track the data.
