Effective with the release of June 2019 data on July 12, 2019, the Producer Price Index (PPI) program updated the net output ratios used to calculate industry indexes based on the North American Industry Classification System (NAICS). With this update, net output ratios are based on 2012 Input-Output Account data from the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce. Net output ratios represent the proportion of an industry's or industry grouping’s output consumed outside its respective area. Previously, net output ratios for calculating NAICS-based PPIs reflected values from BEA's 2007 Input-Output Accounts. This update does not affect Final Demand-Intermediate Demand or Commodity indexes from the PPI.
Further information on this update is available from the PPI Section of Index Analysis and Public Information, at firstname.lastname@example.org or (202) 691-7705.
