Consumer Price Index statistics, preferred measures of core inflation – Bank of Canada definitions, year-over-year percent change, Canada1,2
CANSIM table 326-0023.
The Bank of Canada's preferred measures of core inflation, CPI-common, CPI-median and CPI-trim, are subject to revision. In the case of CPI-median and CPI-trim, this results from the fact that these measures are based on seasonally adjusted price index series. In the case of CPI-common, revisions are due to the statistical technique used, as the factor model is estimated over all available historical data. CANSIM table 326-8023 contains historical release data for these three measures and will be updated every month.
This measure is based on the Consumer Price Index (CPI) series adjusted to remove the effect of changes in indirect taxes.
This measure is based on CPI series that have been treated to remove the effect of changes in indirect taxes, and that have been seasonally adjusted.
CPI-common is a measure of core inflation that tracks common price changes across categories in the CPI basket.
CPI-median is a measure of core inflation corresponding to the price change located at the 50th percentile (in terms of CPI basket weights) of the distribution of price changes in a given month.
CPI-trim is a measure of core inflation that excludes CPI components whose rates of change in a given month are located in the tails of the distribution of price changes.
