Status
This variant of the North American Product Classification System (NAPCS) Canada 2017 Version 2.0 was approved as a recommended standard on October 16, 2018. It replaces the Computer and peripherals prices indexes (CPPI) variant of NAPCS Canada 2017 Version 1.0.
The Computer and Peripherals Price Indexes (CPPI) are monthly series measuring changes over time in the price of computers, computer peripherals and smartphones sold to governments, businesses and households. The methodology for producing these series employs the hedonic method, the result being an index series that tracks pure price change. These index series are used by economists, industry analysts and the general public to track and comprehend events and trends in this important contributor to the Information and Communication Technology (ICT) sector.
Within Statistics Canada, the series pertaining to households are used in the calculation of the Consumer Price Index. Several series are used by the Canadian system of macroeconomic accounts in deflating the value of gross investment by the business and government sectors.
