PPI to Update Samples More Frequently

The Producer Price Index (PPI) periodically updates the sample of producers providing index data in order to reflect current conditions more accurately when the structure, membership, technology, or product mix of an industry shifts. Since 1986, these sample updates have occurred at semi-annual intervals, with the release of data for January and July. Effective with the release of PPI data for June 2015 on July 15, 2015, PPI will update samples on a tri-annual basis, coinciding with the release of data for February, June, and October (in March, July, and November, respectively). This accelerated approach to replacing industry samples will result in indexes that better represent current industry production and will improve data quality.

With each sample update, PPI will continue to publish a notice listing the impacted industries in both the PPI News Release and PPI Detailed Report. In addition, PPI will continue to publish information on specific index additions, deletions, and recodes associated with the updated samples in the PPI Detailed Report.
