Nearly every type of business has one or more trade or professional associations to promote its interests and provide a forum to collect and share information. Many collect and publish industry statistics, reports, and other useful data on their websites or through their publications. Try doing a web search for "trade association [your industry]" to see what you can find. Articles often mention trade and industry associations by name that can then be looked up in these sources.
Use these resources to search for an association for your industry.
