In February 2016, the Real-Time Data Center replaced all PPI and PPI-core vintages, beginning with the vintage for 2014M2 to the most current vintage, with data collected in real-time under the BLS’s new FD-ID aggregation system. Prior to February 2014, the BLS utilized the Stage of Processing aggregation system to construct PPI and PPI-core price-level estimates. [For more information, see http://www.bls.gov/ppi/fdidtransition.htm ]
The entire time-series history for each vintage (column) is available to the public at the vintage date shown in the column header.
For each observation, we report the appropriate values from each vintage that correspond with the statistical agency's first-, second-, and third-release values for that observation. (We also report the values as they appear in the most recent vintage available when we ran our programs.)
Please review the documentation for information on our data collection methods, data sources, and any specific information on this variable.
