We are currently living in a low-growth era, a low birth rate, an aging society, and social problems caused by global warming and environmental pollution. In addition, the introduction of new technologies in the fourth industrial revolution is rapidly reorganizing the industrial structure, and the beginning of the 5G era of ultra-fast, ultra-low delay and ultra-connectedness is bringing various changes not only to related industries but also to our daily lives. In addition, the Corona Pandemic has served as an opportunity for members of society to recognize that the quality of life living in a clean environment is paramount. In response, the study sought to raise the need for more detailed consumer typification to improve quality of life, re-recognition of quality of life, and the importance of psychological health conditions to be recognized as important variables in quality of life. To this end, this study was conducted on the 8th year of the Korean Retirement and Income Study (KReIS) survey conducted by the National Pension Service in 2019. Of the 11,862 people (KReiSP08) of the National Pension Service, which is a reliable panel survey data, 4,303 people aged 65 or older were analyzed, excluding non-response and prospective senior citizens aged 64 or younger. As a result, first, elderly consumers who are sick in both body and mind appeared to have the lowest quality of life in all factors when classified for segmentation of consumers, which seemed to be the group to pay the most attention to. Second, if physical and economic factors are essential as objective factors for the quality of life, re-recognition is necessary considering happy consumption and the quality of life related to happy consumers. Third, ultimately, it seems necessary to subdivide the elderly consumers in various ways, forming and supporting guidelines for promoting psychological and social consumer welfare. This suggests that we should consider not only economic but also psychological and socio-cultural consumer welfare. Ultimately, we propose the need to consolidate the support system and education system by further segmenting consumers to improve quality of life, re-recognition of quality of life, and improve related policies that create and provide various guidelines for promoting happiness through quality of life.
