Flood vulnerability index of Korea in 2022

This data set contains both raw and processed data from the flood vulnerability assessment of 228 districts in Korea as of 2022. The study aims to analyze regional disparities in flood vulnerability using a multidimensional, indicator-based approach that incorporates regional resilience. Based on the IPCC's climate change vulnerability concept, 30 indicators across social, economic, physical, and infrastructural dimensions were constructed. The raw data were standardized and weighted using the entropy method to enhance objectivity.
The results indicate that highly vulnerable areas often exhibit high social and physical sensitivity, combined with low economic adaptive capacity. Additionally, it was found that 69.23% of the highly vulnerable districts are located in metropolitan areas, suggesting that urban regions are at greater risk of flood damage when social, economic, physical, and infrastructural factors are collectively considered. Moreover, over 90% of the vulnerable districts outside metropolitan areas were identified as population-declining regions, highlighting the potential negative impact of depopulation on local flood resilience.
