Lots of people say "tracked inflation", but few understand that inflation is measured relative to a basket of goods, and which basket of goods you pick really matters. Which means that the inflation rate you personally experience will depend on your lifestyle.

The result is that the inflation rate as experienced by the well-off (who consume more luxuries) is generally quite different than the inflation rate as experienced by the poor.

There is no good data that I know of over a long period of time for this. But https://www.chicagofed.org/~/media/publications/working-pape... has estimates for recent years, and it appears that inflation for low income groups is currently significantly higher than for high income groups. Mostly because price differences have been rising between stores available to low income groups versus high income groups.
