Subscription databases, trade publications, and industry or association websites are great places to look for comprehensive, often annual, reports on the marketing industry as whole, or specific types of marketing. Some example reports include:
The North American Industry Classification System is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. The codes can be helpful when searching for industry information in subscription databases or using U.S. Census material. Codes start with two-digits at the broadest industry level, and become more specific at the six-digit level. Mexico, Canada and United States data is comparable at the five-digit code level. Other region, country, and organization-specific industry codes exist for data tracking purposes. Knowing how a particular industry or a company within an industry is classified can help when researching, since information is often organized within these codes.
