When assessing building material cost changes, the primary source for the U.S. is the Producer Price Index (PPI) data series calculated by the Bureau of Labor Statistics (BLS). (The BLS is also responsible for the Consumer Price Index.)
For Canada, one turns to the Industrial Product Price Index (IPPI) and Raw Materials Price Index (RMPI) data series from Statistics Canada.
While the history of the latest PPI numbers (Table 1) extends to January 2018, the IPPI and RMPI figures (Table 2) are currently available only through December 2017.
The PPI results include specific findings for ‘final demand construction’ (i.e., overall construction) as well as private capital versus government investment, plus five specific type-of-structure sub-categories.
