AB - As climate change increases repeated exposure to natural hazards and population aging continues, there is a growing need to consider disaster exposure together with local population structure. This study examines the association between repeated natural hazard exposure and the spatial structure of the elderly population using municipal-level panel data from South Korea for 2015– 2024. Natural hazard exposure is classified into short-term and long-term cumulative exposure, while the spatial structure of the elderly population is measured using Fisher’s z-transformed Moran’s I (FZ Moran’s I), calculated from elderly population ratios at the census-block level. Two-way fixed-effects panel models are employed for the analysis. The results show no significant association between shortterm exposure and FZ Moran’s I, whereas long-term cumulative exposure is significantly and negatively associated with FZ Moran’s I. Supplementary analyses and robustness checks support the consistency of the main findings. These results suggest that understanding the relationship between natural hazards and population aging requires consideration of both the temporal accumulation of disaster exposure and the spatial distribution of the elderly population.
