This is without up to date fact checking so take this with a grain of salt, but during the last housing crisis I remember looking this up and came to the conclusion above. I don't actually know if it's universal but it was valid for Sweden at that point in time. I think the key word in your text above is "expenditure", where a house maybe isn't seen as an expenditure but rather an investment..?

When taking about inflation it's also always good to remind one self that the pool of money also changes. And the fact that housing usually is connected to mortgages, which in turn expands the amount of available money. But this paragraph has nothing to do with your comment so I'll just stop there!

Thanks for your comment. I was a bit intrigued, also in light of the sibling discussion, so I tried to look this up without spending too much time on it.

This document "How is inflation measured?" from the Riksbank: https://www.riksbank.se/globalassets/media/rapporter/ekonomi... doesn't give weights in general but does say this (emphasis mine): "the method in which housing costs for owner occupied housing are measured are an important source of non-comparability, partly because they make up a large proportion of the CPI (around 10 per cent in sweden)". Note the "owner occupied" part, so this isn't even just rents! But then I don't understand the rest of the discussion that follows this.

Also Statistics Sweden at https://www.scb.se/en/finding-statistics/statistics-by-subje... lists "Housing, water, electricity, and fuels" as one of the "main groups" in the CPI, though this only suggests but does not prove that housing does have a non-zero weight.
