Final answer:
Age is a key factor in demographic segmentation and not an exception. Demographic segmentation is based on factors like age, gender, and income, allowing businesses to target specific consumer groups effectively.
Step-by-step explanation:
Demographic segmentation can indeed be done by age, which makes it one of the core methods of segmentation in marketing. Demographic segmentation involves dividing a market into segments based on demographic factors such as age, gender, income, education level, family size, occupation, religion, race, and nationality. Among these, age is a critical demographic factor as consumer preferences often vary significantly with age.
For example, the types of products and marketing approaches that appeal to teenagers will differ greatly from what might appeal to senior citizens. A company can tailor its products, services, and marketing campaigns to meet the specific needs of different age groups, thereby improving its market reach and efficiency. Since age is a standard criterion for demographic segmentation, we can conclude that it would not be an exception to the methods by which demographic segmentation can be done.
