Three-country comparability of the North American Industry Classification System (NAICS) 2002 NAICS 2002 has a five-digit classification structure, with a six-digit for national industries. With some important exceptions, it provides a set of standard 5-digit industries that describe the industrial structure and composition of the Canadian, United States and Mexican economies at selected levels of aggregation where agreement occurred among the three countries on a compatible classification. Below the agreed-upon level of compatibility each country has added additional detailed six-digit industries, as necessary to meet national needs, provided that this additional detail aggregates to the NAICS level. Exceptions to the rule of five-digit industry level NAICS compatibility are shown below in a table. Exceptions to the rule of five-digit industry level NAICS 2002 comparability
* Subsector 526 in Finance is a NAICS Canada subsector only.
Separate agreements providing for detailed industry comparability between Canada and the United States were reached for the utilities; retail trade; and finance and insurance sectors. Differences in NAICS 2002 Manuals
In many cases, the national detail in the NAICS Canada and NAICS US Manuals are similar. Note that residual 6-digit classes can end in either and 8 or a 9. Within each sector, the country with the larger number of 6-digit classes identified their residual classes with a code ending in 9. As a rule, the 6-digit classes of the three countries carry the same code when they refer to similar industries and different codes when they refer to different industries. However, in rare instances, when the combined number of Canadian and US 6-digit classes exceeded 10, this resulted in an identical code for classes with a different content. There are only 3 such cases, viz:
In the published paper version (12-501-XPE), comparable NAICS classes are identified by using the following superscripts:
