The United States federal government gathers and publishes data and information about domestic industries.
Need an SIC or NAICS code in order to search for industry analysis? Instead of trying to look it up, do a company search for a company that, in your mind, represents that industry. For example, in order to determine the SIC code for coffee, do a company search for Starbucks. A company profile will typically include the relevant industry codes and links to corresponding industry reports. It's always good to note such industry codes as you encounter them--you'll have them when you need them!
