社会阶级
Customers may be sorted based on social class, lifestyle, or personality characteristics (Kotler et al., 2014). According to Kotler et al., (2014) people who in the same demographic area can have completely different psychographic characteristics. Marketers generally segment target markets into consumer lifestyles and their social class. Social class has a large effect on preferences for cars, clothes, home furnishings, leisure activities, reading habits, and retailers (Kotler et al., 2014).
