VALS is a psychographic segmentation methodology used to understand consumer needs and identify market trends based on values, attitudes, interests, and lifestyles. Originally developed in the 1970s, VALS segments U.S. consumers into 8 groups based on survey responses. The groups include Innovators, Thinkers, Achievers, Experiencers, Believers, Strivers, Makers, and Survivors. Each group is defined by personality traits and purchasing preferences. VALS analysis helps tailor marketing strategies to different demographic segments.
