Objective : This study analyzed time use and volition across occupational areas among the MZ generation to provide foundational data for understanding healthy lifestyles and occupational balance. Methods : The Occupational Questionnaire was administered to 200 young adults in Jeonbuk Special Self-Governing Province. Descriptive statistics and independent t-tests examined differences by gender and generation. Open-ended activity responses were organized according to participant-selected occupational areas. Results : No significant gender differences were found in overall time use or volition, whereas generational differences were identified. Millennials spent more time in work, while Generation Z allocated more time to recreation. For volition, significant generational differences were found in personal causation for activities of daily living and rest, and in value across work, activities of daily living, recreation, and rest. Generation Z showed relatively higher personal causation in activities of daily living and rest and placed higher value on work, activities of daily living, and rest, whereas Millennials placed higher value on recreation. Conclusion : Gender differences in occupational participation tended to be attenuated, while time use and volition differed by generation. These findings highlight the need to understand the Korean MZ generation within generational life contexts and subjective perceptions of occupations.
