Why does REDDI use both the Standard Industrial Classification (SIC) and North American Industrial Classification (NAICS)?
For Census Sub-Divisions and Census Divisions, REDDI’s Competitive Advantage Analysis uses Standard Industrial Classification (SIC) employment data, rather than NAICS (North American Industrial Classification System). The SIC classification system was used to classify employment data from the 1996 Census, but NAICS was used for the 2001 Census. Consequently, obtaining an accurate measure of employment change by sector between 1996 and 2001 was not possible, until late 2003, when Statistics Canada released the 2001 employment data with sectors classified using SIC.In comparison, the Labour Flow Analysis option at Step 3 enables you to generate location quotients for both the resident labour force and jobs located within the community. Labour Flow Analysis is also based on 2001 employment data, classified by sector using NAICS.
