Abstract

This study empirically analyzed the impact of regional population changes on public library use, aiming to provide a foundation for developing population-responsive library management strategies. The research focused on City Y, which experienced significant demographic fluctuations between 2019 and 2024. Correlation and multiple regression analyses were conducted using population statistics from the Ministry of the Interior and Safety and library usage data from the National Library Statistics System. The results showed that the total population of City Y had a significant positive correlation with interlibrary loan activities. More importantly, local(sub-regional) population figures were positively associated with most usage indicators, including visitor numbers, circulation volume, and collection turnover rates. In addition, factors such as library floor area and operating expenses were identified as key variables influencing utilization levels. These findings suggest that library use is more strongly affected by demographic characteristics within localized living zones than by the city’s overall population size. Consequently, differentiated strategies for spatial expansion and budget allocation that reflect local demographic shifts are essential for achieving sustainable and equitable public library development.
