A good resource for data about an industry are trade organizations/ associations. Sometimes you can find information freely available on their websites. Other times, the data is for member's only. It's worth taking a look, at least to see what sources they are citing. If the research is conducted by a 3rd party, you may be able to contact them directly for access.

When you click on Advanced Search, the drop-down box gives you the option of searching for Associations by Name, NAICS/SIC Code, description, etc.
