There may be some adjusted CPI #'s you may be referring to. I'd take a glance around bls.gov to familiarize yourself with what our government does, their methodology, and what these numbers mean.
*Edit* Sorry for the USA centrism on this one. I don't know off hand any global calculations for inflation, nor how practical they'd be for any single person's living situation. For that matter a CPI for all of the USA would probably be entirely impractical for an individual as well. :)
To go further with that idea you can also just track your expenses and come up with a personal inflation rate by comparing your costs from year to year.
