Median CPI

  • Description: We calculate the median CPI and the 16 percent trimmed-mean CPI based on data released in the Bureau of Labor Statistics’ monthly CPI report.
  • Median CPI is the one-month inflation rate of the component whose expenditure weight is in the 50th percentile of price changes.
  • 16 percent trimmed-mean CPI is a weighted average of one-month inflation rates of components whose expenditure weights fall below the 92nd percentile and above the 8th percentile of price changes.
  • Benefits: By omitting outliers (small and large price changes) and focusing on the interior of the distribution of price changes, the median CPI and the 16 percent trimmed-mean CPI can provide a better signal of the underlying inflation trend than either the all-items CPI or the CPI excluding food and energy (also known as core CPI).
