| The trimmed mean
PCE inflation rate is an alternative measure
of core inflation in the price index for
Personal Consumption Expenditures (PCE).
It is calculated by staff at the Dallas
Fed, using data from the Bureau of Economic
Analysis (BEA). |

August 2008
The trimmed mean PCE inflation
rate for August was an annualized 2.2 percent. According

The following chart plots the
evolution of the distribution of price increases in
the monthly component data over the past year. The chart
shows the percentage of components each month, weighted
by their shares in total spending, for which prices
grew between 0 and 2 percent (at an annual rate); between
2 and 3 percent; between 3 and 5 percent; between 5
and 10 percent; and more than 10 percent.
