NOTE: 1982-1984=100: The consumer price index for a specific
item is a weighted average of the prices for the individual components of the
item. The weights are determined by the expenditure shares of the individual
components based on a survey of consumer expenditure during the base year(s).
The base year price is then normalized to 100. For some items, BLS establishes
weights using several years of consumer expenditure surveys in order to smooth
out the effects of short-term price shocks and of the business cycle. Weights
formed using several years will give a more accurate measure of typical consumer
expenditure patterns.
