In addition to the above print resources, there are specialized database resources that will also provide industry ratios:
D&B Key Business Ratios
The Dun & Bradstreet online version provides 14 key business ratios, covering solvency, efficiency and profitability. Users may calculate industry ratios (choosing an industry, year, and asset range), and then use the 'comparative analysis' function to enter in the figures from an individual company’s financial statement to generate a comparison of the company’s own business ratios with the industry.This is the only Sawyer Library database specifically devoted to industry ratios.
[FIND D&B Key Business Ratios on our "Databases by Subject" List in the "Business and Management" category.]
Other Sawyer Library databases may include some financial ratios in their overall discussion of companies and industries:
Standard and Poor's NetAdvantage: Industry Surveys
Although Standard and Poor's does not provide industry averages, the Comparative Company Analysis section of each survey does provide profit-, balance sheet-, and equity ratios for specific companies.

Value Line Research Center
In addition to specific company and stock information, Value Line Survey Issues provide a one page Industry Commentary of each industry covered by Value Line. These commentaries frequently include a chart of retrospective and estimated composite statistics, such as the Net Profit Margin. The print version of Value Line is available at the Sawyer Library Reference Desk.
