The new generation differs significantly from older generations in traditional value orientations and consciousness structures, and also exhibits marked differences in consumption behavior. Therefore, understanding the consciousness structures and consumption behavior characteristics of the new generation is highly meaningful. This study investigated whether basic consciousness structures related to clothing, food, and housing—which are relatively resistant to change due to personal habits and social traditions—show significant differences across age groups. For this purpose, face-to-face interviews were conducted with 1,000 males and females aged 17 and above residing in the Seoul area, yielding 824 usable responses. Factor analysis was performed to reduce individual items related to clothing, food, and housing into several factors, and analysis of variance (ANOVA) was conducted to examine how the extracted factors differed across age groups. Additional analysis was performed using traditional value orientation as a mediating variable to explore why basic consciousness structures related to clothing, food, and housing differ across age groups. The results showed that age group has a significant influence on basic consciousness structures related to clothing, food, and housing. This implies that a multi-group classification from teenagers to those aged 40 and above is more effective than a dichotomous distinction between the new generation and the non-new generation. Additional analysis revealed that traditional value orientations differed significantly across age groups. However, the correlations between traditional value orientations and the basic consciousness structure factors were mostly low, indicating that differences in basic consciousness structures cannot be explained by traditional value orientations alone. Rather, demographic variables such as education level, gender, and marital status were found to have a substantial influence on basic consciousness structures related to clothing, food, and housing. Finally, the study's limitations and directions for future research were presented.
