There are so many groups, beyond industry and market report providers, who provide insight, data, and statistics about industries.
Industry Associations
Industry and trade association websites often contain industry news and information, although some data may be available to members only. Look for sections called: "news," "research," "resources," "library," or "data."
Industry Analyst Reports
Analyst reports are written by Wall Street analysts and typically focus on factors that would influence a public companies performance. Analyst reports can be focused on companies, industries, or regions.
Industry News & Publications
Sometimes, the only information available are from news and trade outlets (i.e. AdAge, Chronicle of Higher Education, Auto News Daily, etc.). You can get some access through search engines, but for more advanced searching and more coverage try the following.
Governments, IGOs/NGOs, and Regulators
Governments and IGOs/NGOs (like the World Bank) around the world tend to release a lot of economic, demographic, and industry data they collect.
Regulators can be government agencies (like the FDA for pharmaceuticals in the US) or professional groups that control professional standards and licenses. Many of these organizations collect and make available all sorts of data and information.
