Notes:               Average consumer prices are calculated for household fuel, motor fuel,
                     and food items from prices collected for the Consumer Price Index
                     (CPI). Average prices are best used to measure the price level in a
                     particular month, not to measure price change over time. It is more
                     appropriate to use CPI index values for the particular item categories
                     to measure price change.
                     
                     Prices, except for electricity, are collected monthly by BLS
                     representatives in the 75 urban areas priced for the CPI. Electricity
                     prices are collected for the BLS for the same 75 areas on a monthly
                     basis by the Department of Energy using mail questionnaires. All fuel
                     prices include applicable Federal, State, and local taxes; prices for
                     natural gas and electricity also include fuel and purchased gas
                     adjustments.
