Segmentation is the process of dividing a market into distinct groups that have different needs or behaviors. A large company like BAT segments the market geographically by country and region, demographically by age, gender, income, and occupation, psychographically by social class and lifestyle, and behaviorally by user rate. Geographic segmentation divides markets into countries and regions like the Americas, Western Europe, and Asia. Behavioral segmentation categorizes customers based on their usage rate as light, medium, or heavy users.
