I am genuinely trying to understand this. You initially said it was irrelevant without age adjustment but based on your most recent post it seems your point is really more about household size and less about age.

The home price angle makes sense but still doesn't fully explain why Utah is passing other states up so quickly. Everyone saw home prices rise dramatically relative to income. Texas more-so than Utah. Utah also had one of the worst supply issues and very few homes were moving. How in the world did debt rise so fast with more kids coming of age and almost no homes being sold? To me the most logical answer is people spent way more than they should have on the few homes that moved.

Not at all trying to be combative. I just seem to see holes in the age explanation. I think there is more to it. My anecdotal experiences in Utah are definitely pushing me to some confirmation bias too. Since moving to Texas I just see people approaching home and car buying so differently than in Utah.
