Comparability of Producer Price Indexes and Import Price IndexesThe Bureau of Labor Statistics (BLS) publishes both Producer Price Indexes (PPIs) and Import Price Indexes (MPIs) classified according to the North American Industry Classification System (NAICS). This allows for the possibility of comparing price trends using NAICS-based PPIs and MPIs. There are, however, important potential differences between PPIs and MPIs that data users should consider before comparing the two series. The PPI-MPI Comparability Table, available for download below, assists data users in determining comparability between PPI industry net output indexes and MPI industry indexes by providing data on these potentially important differences. A full description of the data included in the table, explanations of potential differences between PPIs and MPIs, and comparison examples can be found in the Monthly Labor Review (MLR) article Comparing NAICS-based PPI Industry Net Output Data and International Price Program Import Data. The PPI-MPI comparability table is structured as followed:
When all else are equal, comparability between a PPI and MPI industry group index increases with
When using this table, data users should keep in mind these important caveats:
