Marketers typically combine several variables to define a demographic profile. A demographic profile (often shortened to "a demographic") provides enough information about the typical member of this group to create a mental picture of this hypothetical aggregate. For example, a marketer might speak of the single, female, middle-class, age 18 to 24, college educated demographic. Marketing researchers typically have two objectives in this regard: first to determine what segments or subgroups exist in the overall population; and secondly to create a clear and complete picture of the characteristics of a typical member of each of these segments. Once these profiles are constructed, they can be used to develop a marketing strategy and marketing plan. The five types of demographics in marketing are age, gender, income level, race and ethnicity. Basically, Brandwise and other marketing firms help clients develop a target audience demographic in order to be able to reach them through, advertising, direct mail, trade show exhibiting, web promotions, email marketing, etc. This is an important step in targeting and segmenting your audience. A well defined strategic demographic of your customers and prospects is half the battle in new client conversion. It also leads into the next phase of creating buyer personas which helps in both marketing and sales.
