Critics of the consumer price index—the most widely watched inflation measure—contend that it overstates inflation by as much as 1 percentage point a year.

A closer look at these alternatives, however, reveals that they have substantive problems of their own, suggesting that the CPI, though flawed, is still our most reliable indicator of changes in inflation.
