Archived - How to read the concordance table - NAICS 2012 and ISIC Rev. 4

The concordance of the North American Industry Classification System (NAICS) Canada 2012 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 concordance is shown at the lowest level of both classifications, namely at the 6-digit level in NAICS and the 4-digit level in ISIC except in the three cases where the link is to a 3-digit ISIC code, where more precise links to ISIC are not possible.

The relationships between the two classifications can be simple or complex. The following examples are presented to illustrate how the table should be read.

In the first example, a NAICS class(first two columns: code, title) links exactly to one ISIC class (third and fourth columns: code, title), their coverage of activities being the same. All of the activities in NAICS 212210 are found in ISIC B0710.

In the second example, each NAICS class(first two columns: code, title) links to a portion of the same ISIC class (third and fourth columns: code, title). Each of NAICS 311340, 311351 and 311352 is a subset of ISIC C1073. The last column contains explanatory notes.

An asterisk attached to the ISIC alpha-numeric code indicates that a NAICS class is equal to a portion of an ISIC class. The explanatory note provides a short description of the nature of the overlap between the NAICS and ISIC classes.

In the third example, a NAICS class(first two columns: code, title) is equivalent to more than one ISIC class. NAICS 115210 is equal to ISIC A0162 plus a portion of ISIC M7500. The last column contains explanatory notes.
