Producer Price Index
The Producer Price Index, or PPI, measures the average change over time in the selling prices received by domestic producers for their output. Prices included in the PPI are based on the first commercial transaction for many products and for some services. Effective with the January 2014 Producer Price Index (PPI) data release in February 2014, BLS transitioned from the Stage of Processing (SOP) to the Final Demand-Intermediate Demand (FD-ID) aggregation system. Read more on the FD-ID transition. Detailed Producer Price Index data is available from the Bureau of Labor Statistics.
