This document discusses social class and how it relates to consumer behavior. It defines social class as the hierarchical division of society based on status. Status consumption, where people try to increase their social standing through consumption, is important for luxury goods. Social class can be measured subjectively based on how individuals view their own class, reputationally based on how others view their class, and objectively based on socioeconomic factors like occupation, education and income. Marketers must consider the behaviors and preferences of different social classes like the affluent, middle class, working class and techno class when developing marketing strategies.
