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.
