Background
- In recent years, rapid changes in both the U.S. and world economies brought the SIC under increasing criticism. The 1991 International Conference on the Classification of Economic Activities provided a forum for exploring the issues and for considering new approaches to classifying economic activity. In July 1992, the OMB established the Economic Classification Po…
Reception
- The ECPC and Statistics Canada reviewed the existing structure of detailed 4-digit industries in the 1987 U.S. SIC and the 1980 Canadian SIC for conformance to economic concepts.
Structure
- NAICS industries are identified by a 6-digit code, in contrast to the 4-digit SIC code. The longer code accommodates the larger number of sectors and allows more flexibility in designating subsectors. It also provides for additional detail not necessarily appropriate for all three NAICS countries. The international NAICS agreement fixes only the fi...
Subdivisions
- Many of the new sectors reflect recognizable parts of SIC divisions, such as the Utilities and Transportation sectors, broken out from the SIC division Transportation, Communications, and Utilities.
