Effective with the release of data for January 2021 on February 17, 2021, the Bureau of Labor Statistics will update the weight allocations used to calculate the Producer Price Index (PPI) Final Demand-Intermediate Demand (FD-ID) indexes to more accurately reflect recent sales patterns. While PPI commodity index weights will continue to be based on shipment values from the 2012 economic census, the proportions of these weights allocated to the various FD-ID categories will change. The new allocations will be based primarily on data from the 2012 Input-Output Accounts produced by the Bureau of Economic Analysis.
It is important to note that the allocation update will not change the PPI commodity classification system, reference base, the FD-ID aggregation structure, or historical index data. It may, however, result in substantial shifts in the relative importance figures of certain commodity components that make up the FD-ID indexes.
Relative importance figures tables for December 2020, which detail the shift from 2007 to 2012 input-output relationships, will be available on February 12, 2021 on the BLS website at www.bls.gov/ppi. This information also may be requested from the PPI Section of Index Analysis and Public Information through e-mail to email@example.com or by calling (202) 691-7705.
