Trade association websites often have reports on consumer data if the trade is primarily made up of business to consumer companies, although some data is available to members only. Market research firms, which in general require a purchase to see a full report, frequently have summaries, trending reports, or blog articles freely available online.
Another option are research centers, which unlike market research firms, generally are nonprofit and allow more access to reports and data. Below are links to a few examples of available data online and we have included notes on how freely accessible the information is.
Content that is primarily subscription-based can be found on the subscription sources section of this guide.
