With the release for the December 2010 New Housing Price Index (NHPI) (table 5), the Producer Prices Division updated the new housing price indexes by changing the base year from 1997 to 2007.

The 2007=100 NHPI series is available retroactively from January 1981 in CANSIM table 327-0046 but has different vector numbers. The 1997=100 based NHPI continues to appear in table 327-0005, however, the 1997=100 based index has not been updated after November 2010. Since the index has been mathematically rebased between January 1981 and November 2010, the index movement for that period is the same for the 1997=100 and 2007=100 series. To assist users, a vector number concordance table found in Appendix I will help users link the new series to the old.

Tables 1 and 2 of this publication have been updated with Industrial product price indexes (IPPI) based in 2002=100. Starting with the release of August 2010 reference month data, the basket of goods used to calculate the IPPI was updated to reflect the sales and expenditures in 2002. This update is to better reflect important changes in production patterns of manufacturers in Canada. The basket must be changed from time to time to ensure that too much importance is not given to some products and too little to others.

The update includes two major changes: the weights of various items in the basket of goods used to calculate the index, which was based on 1997 data, will now be based on 2002 data; and the IPPI base year (the period for which the value 100 is assigned to the index) has changed from 1997 to 2002.

A vector number concordance table between the series contained in the new and old tables is available.
