Producer Price Indexes

PPI Introduces Wherever‐Provided Services and Construction Indexes

Effective with the release of July 2009 data on August 18, 2009, the Producer Price Index (PPI) of the Bureau of Labor Statistics (BLS) introduced a new set of wherever-provided (WEP) services and construction price indexes. Wherever-provided price indexes measure price change for services regardless of the producers’ industries of origin. For example, the WEP index for air transportation of freight measures price change for air transportation of freight from all industries that provide air transportation of freight. For a methodological overview of WEP indexes, please visit For a more detailed review of WEP indexes, see
