Abstract This study analyzed network characteristics to understand population mobility in Gyeongsangnam-do before and after COVID-19. Mobile travel data from September 2019 and 2020 were compared to analyze daily movement during the same period. Data from 22 cities and counties in Gyeongsangnam-do and 16 cities and provinces nationwide were analyzed using network statistics and block modeling techniques. The analysis showed that movements were simplified into five blocks after COVID-19, compared with six blocks before, indicating a simpler movement pattern. Urban migration may continue regardless of surrounding areas, post-COVID-19. When a metro area's population surpasses half of the total population, fundamental measures are needed to address population concentration. Emphasize regional hub cities in development policies. This study is significant because it demonstrates changes in population movement in Gyeongsangnam-do before and after COVID-19 using centrality and movement pattern analysis. To fully understand population movement in Gyeongsangnam-do, analyze data on freight, information, and capital movement, as well as distance between regions, in conjunction with the study results. Address these limitations in future research.
