Company Research: Industry Surveys, Ratios, NAICS/SIC

Industry Ratios

The purpose of calculating industry ratios is to evaluate your chosen company's strengths and weaknesses as compared to those of competing businesses in that industry. The ratios, or averages, are arranged by Standard Industrial Classification (SIC) and/or North American Industry Classification System (NAICS) codes. The Sawyer Library subscribes to several resources which provide these ratios, some are electronic, and some are in print.

The purpose is to allow for industry averages and ratios to be comparable between all three North American nations, and to include newer industries not covered by the SIC codes. There are several government websites available for searching the NAICS codes:
