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/ekonomiska-kommentarer/fore-2017/engelska/2015/rap_ek_kom_nr5_150519_eng.pdf 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-subject-area/prices-and-consumption/consumer-price-index/consumer-price-index-cpi/pong/tables-and-graphs/consumer-price-index-cpi/cpi-indices-for-main-groups-annual-averages/ 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.
