For those of you dealing with inflation and the Consumer Price Index (CPI) in your classes, there are two great interactive graphics (HT to Chartporn) that you can use.
This one is from The Wall Street Journal and lets you compare the price behavior of any of the CPI components to the overall CPI and the core CPI.
Another excellent graphic is this one from The New York Times in 2008. It shows how all of the components are weighted within the various categories.
If for some reason you have trouble getting to either of these, go to the Chartporn post andclick directly on either the second or third chart. (You may have difficulty getting through toChartporn because of the school filters.)
Let me know what you think.
