Many types of data are published as outputs from the CPI program. The most popular are indexes and percent changes. Requested less often are relative importance (or relative expenditure weight) data, base conversion factors (to convert from one CPI reference period to another), seasonal factors (the monthly factors used to convert unadjusted indexes into seasonally adjusted indexes), and average food and energy prices. Index and price change data are available for the U.S. city average (or national average), for various geographic areas (regions and metropolitan areas), for national population-size classes of urban areas, and for cross-classifications of regions and size classes. Indexes for various groupings of items are available for all geographic areas and size classes.
