This document categorizes consumers into 4 groups based on lifestyle rather than income: Mainstreamers who value security and belonging, Aspirers who seek status symbols and esteem, Succeeders who already have status and control, and Reformers who define themselves through self-esteem, self-fulfillment, and are socially aware and anti-materialistic. The groups make up different percentages of the population and have different priorities in how they live their lives and view material goods.
