The correspondence of the North American Industry Classification System (NAICS) Canada 2022 Version 1.0 to the International Standard Industrial Classification of all Economic Activities Revision 4 (ISIC Rev. 4) is shown in the table below. The table shows the Canadian interpretation of the relationships between the two classifications.
The Generic Statistical Information Model (GSIM) is now used to identify the types of changes made to the classification. Real changes (RC) are those affecting the scope of the existing classification items or categories, whether or not accompanied by changes in the title, definition and/or the coding. Virtual changes (VC) are those made in coding, titles and/or definitions, while the meaning or scope of the classification item remains the same. The "real changes" are the most important ones to note for analysis.
NAICS 2022 Version 1.0 is the biggest revision to NAICS since 2002. The overarching theme to the updates is the digital economy. The guiding principle of these changes is to classify economic activities based on digital platforms, and those offered on other forms over the Internet, in the same groupings as their non-digital equivalents.
