Un-skewed economic data

My own personal experience is the opposite.  Looking at my household spending over the last decade, of which I pretty much track every dollar, since I got married I would say my personal CPI is lower than the official CPI and much closer to Chained CPI.  I think the main factor here is the composition of spending any one household is likely to experience.   If a household has heavy medical or educational spending concentration over the last decade they will experience higher personal CPI than the government figures.  If a household has heavy spending concentration in food or durable (especially electronic ones) then they will fact a personal CPI lower than what the government figures might contain.
