It provides services such as target marketing, market analysis, site evaluation, and direct marketing. One of its database systems merges business data with census data. The system classifies every U.S. household into one of 50 market categories. Those categories can then be used for a variety of marketing purposes. In addition, a business's information on its own customers can be incorporated into a specialized program designed by the client and National Decision Systems (Thomas and Kirchner, 1991:218-219).

In addition, there are several marketing and demographic information firms that produce marketing and demographic analysis programs specifically for use by the health care industry.
