As well as what you don't spend your money on. I find it ridiculous that the "housing" index includes not only rent and utilities but the cost of a 40" flat-screen TV. That belongs under "entertainment".
Also, several items are sufficiently vague that they have a huge price range; for instance, "1 pair of sport shoes (Nike, Adidas, or similar)" or "Daily menu in the business district". Far too subjective to serve as a basis for comparison; in the same city, those values could vary by 2-3x depending on taste.
