  Abstract

This study empirically reviewed telecommunication data and credit data through pseudonymized data integration to analyze the activity range according to the income level of the elderly population in Busan City. Using data collected over 20 months from January 2022 to August 2023, we analyzed the differences in the scope and patterns of elderly people’s activities based on their income level and found that the high-income elderly group engages in a much wider range of activities than the low-income elderly group. They operate across broader geographical areas and have greater access to diverse social and cultural resources. In particular, the high-income group exhibited varied lifestyle patterns between weekdays and weekends, such as visiting distant commercial districts on weekdays and enjoying leisure time at nearby parks on weekends. On the other hand, low-income individuals mainly engaged in activities near their residences, with no significant differences in their activity range between weekdays and weekends. These findings highlight the impact of income level on the mobility and living patterns of the elderly, offering valuable insights for urban planning and welfare policy development. This study contributes to the formulation of a more comprehensive and effective urban management strategy by suggesting policy directions aimed at improving elderly welfare and promoting social integration.
