Explanation:

The main difference between demographic and geographic segmentation is that demographic segmentation categorizes customers based on factors like age, education, income level, and ethnicity, while geographic segmentation categorizes customers based on their geographical location.

Market segmentation refers to the process of dividing a target market of a product or service into smaller, more defined categories. In this process, customers are categorized into different groups with similar characteristics like age, gender, location, and interests. Furthermore, there are four main types of market segmentation: demographic, geographic, psychographic, and behavioural segmentation.
