Bank of Canada’s Preferred Measures of Core Inflation

The Consumer Price Index (CPI) is an indicator of changes in consumer prices experienced by Canadians. It is obtained by comparing, over time, the cost of a fixed basket of goods and services purchased by consumers. Based on the CPI, Statistics Canada also produces and publishes the Bank of Canada's three preferred measures of core inflation: CPI-trim (trimmed mean), CPI-median (weighted median), and CPI-common (common component). The following infographic looks at the three preferred measures of core inflation and illustrates how they are calculated.
