I was looking at the CPI numbers this morning and noticed something interesting. For some reason, the CPI puts education and communications together in the same category:
I can think of one good reason to group the two together: to hide the inflation rate of education. To see what I mean, take a look at this graphic I put together that shows the total and average annual rates of inflation for each of the categories:
Wow. Look at the three subcategories for education compared to the subcategories for communications. Then, notice the the numbers for the education and communications category as a whole. No wonder why the BLS puts these two in the same category.
