Consumer Price Indices for Transportation, U.S. City Average (monthly data,
seasonally adjusted)
The Consumer Price Index (CPI) tracks the price of a market basket of goods
and services purchased by U.S. households over time. Both monthly and annual changes
are reported in the tables for the CPI in order to facilitate comparison with
other series.

NOTES: 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.
The base period of the original index is 1982-84. January 1992 is set to be
the new reference point (=100) by dividing the values of the original index by
the value of January 1992 in the original index. It is important to point out
that this process changes only the reference point, and not the base period of
the index because the weight structure of the index did not change.
