What are the data sources for QIRI?
The QIRI program has two major data components. For simple units (those which operate in only one province and one NAICS), only GST data are used. These tend to be smaller businesses. GST sales revenue is considered a very good proxy for operating revenue. For complex units (those which operate in more than one province and/or in more than one NAICS), a survey is used to collect information from respondents on operating revenue by province. Complex units tend to be larger businesses. Since all in-scope complex enterprises are surveyed, the survey is, in fact, a full census. These data are combined and aggregated and then converted into an index.
