Effective with the release of January 2015 data on February 18, 2015, 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 now based on 2007 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. Prior to this update, net output ratios for calculating NAICS-based PPIs reflected values from BEA 2002 Input-Output Accounts. This update does not affect Final demand-Intermediate demand or commodity indexes from the PPI.
