To use some sources you will need a NAICS or SIC code for your industry.
North American Industry Classification System
The NAIC System assigns numerical codes to industries from two to six digits. Shorter codes represent broader industry sectors. Be sure to read the full description of the NAICS code, as it may include a broader array of products/services than you might assume.
Standard Industrial Classification Manual (at OSHA site)
The SIC system assigns numerical codes to industries from two to four digits. Shorter codes represent broader industry sectors. Be sure to read the full description of the SIC code, as it often includes a broader array of products/services than you might assume.
Statistical information on industries often originates from government sources. The U.S. government has the resources and expertise to produce high quality statistics. Sometimes private companies update government statistics or repackage it in more convenient forms. Industry associations and private companies may also produce statistics not available from government sources.
Be careful!
When using statistics you may need to read introductory material and footnotes, so that you understand what the statistics were designed to measure and any limitations of the statistics.
The Census Bureau produces may useful statistical series for industries. These sites can take some work to figure out, but they are free. Statistical tables can often be manipulated or downloaded in useful forms.
