Psychographics is the study of personality, values, opinions, attitudes, interests, and lifestyles. It focuses on interests, attitudes, and opinions (IAO variables) to segment populations. Psychographic research in fields like marketing, demographics, and social research can provide valuable insights into individuals and communities. Psychographics variables include personality, values and beliefs, lifestyles, and social class. Social class is determined by measuring objective facts like wealth and education level as well as subjective factors like how people identify themselves.
