Final answer:
The example of marketers gathering data to develop segmentation refers to the 'Identifiability and measurability' criterion, which is about identifying market segments and measuring their characteristics.
Step-by-step explanation:
To develop a successful segmentation scheme, marketers gather data about the population within specific geographic boundaries, the number of people in various age categories, and other social and demographic characteristics. This example describes the criteria of Identifiability and measurability which is one of the four basic criteria used to develop useful segment schemes. Identifiability and measurability refer to the ability to identify distinct segments within a market and quantify their characteristics. These can include demographic data such as age, gender, income, and education, as well as other social, economic, or cultural factors.
Demographic data are crucial for businesses and organizations looking to connect with their target audience effectively. Major sources of such data include vital statistics registries and censuses conducted by governments, which provide insights into the composition of populations. Whether it's political parties gauging voter reactions, public libraries identifying user demographics, or electronics stores understanding customer age profiles, the ability to measure and identify market segments is central to informed decision-making and strategic marketing efforts.
