I have data for household budget going as far back as 1999. Though not everything can be inferred from that data simply because of lifestyle changes, e.g. getting married, moving to different cities, education, and changing dietary habits (cutting sugar, cutting salt, eating out less, consciously choosing less processed foods).

But 2013 to 2019 was a stable period with few lifestyle changes and the trend was around 6% per year for my "basket of household items" with the occasional bumps of "milk just went up by a dollar at the local Food4Less lower tier grocery store." The largest inflationary food items I've seen have been meat and poultry.

The largest non-food inflationary items I've seen are gasoline and health insurance. Car insurance I cannot track due to a minor "at fault" accident adjusting insurance rates in 2018. Storage locker increases by around 4% per year. Household insurance increases by around 5% per year.

My life is only a single, but extensively tracked, data point. But "something seems screwy in the state of Denmark" to paraphrase Shakespeare.

P.S. I'm not in Denmark.
