### Spatial Distribution of Key Facilities for Vulnerable Populations  
To ensure that the most current information was used in the analysis, we established a process for automatically collecting, cleaning, and analyzing raw data. This process is crucial for continuously updating our dataset and ensuring that our analysis reflects the latest conditions. Specifically, we focused on identifying areas with a high concentration of facilities serving vulnerable populations and visualizing regions where medical facilities are lacking. The analysis targeted several key components to understand the distribution and accessibility of facilities used by vulnerable populations. First, we constructed a comprehensive dataset of medical facilities, including hospitals and clinics, with a focus on their geographical locations and overall accessibility. To assess accessibility, we generated isochrone maps depicting areas within specific walking distances of these medical facilities. Additionally, we expanded the analysis to include spatial data on other critical facilities, such as primary schools, daycare centers, kindergartens, and senior centers. These facilities play a vital role in supporting vulnerable populations, and their inclusion in the spatial data analysis was essential for developing a complete picture of the overall infrastructure available in the district. By integrating these spatial data, the analysis provided valuable insights into both the concentration of these facilities and the ease of access for the populations who rely on them. The data sources for the analysis included two primary datasets. The first was the Medical Facilities Licensing Data, which provided comprehensive information on the number and location of hospitals and clinics throughout Gangeo District. This dataset was instrumental in mapping the distribution of medical facilities. The second dataset comprised the Standard Data for Facilities for the Elderly and Children, which contained detailed information on the locations of senior centers, daycare centers, kindergartens, and primary schools. These data were essential for understanding the spatial distribution of key support facilities for vulnerable populations within the district. To analyze the data, we employed several analytical techniques to create visual representations that clearly illustrate the spatial distribution of key facilities. Specifically, we processed the spatial data for medical and senior centers to produce detailed visualizations depicting their distribution across Gangeo District. These visualizations were crucial for identifying areas of high facility concentration and regions where these essential services are less accessible to vulnerable populations. A comprehensive map was generated categorizing hospitals and clinics into four types: internal medicine, obstetrics and gynecology, pediatrics, and otorhinolaryngology (ear, nose, and throat; Figure 3). This classification helped to understand the distribution of these key medical services. As of July 2024, there were 322 hospitals and clinics across the Gangeo District, excluding duplicates among the specified medical departments. The highest concentrations were found in Banghwa 1-dong, Balsan 1-dong, and Hwagok 1-dong. In contrast, areas such as Deungchon 2-dong, Banghwa 3-dong, and Gayang 3-dong were found to have fewer medical facilities. Notably, obstetrics and gynecology services were absent in Hwagok 2-dong, Deungchon 2-dong, and Gayang 3-dong, indicating potential vulnerabilities in these regions. Another map was created to illustrate the distribution of facilities for the elderly and children, including senior centers, daycare centers, kindergartens, and primary schools, as shown in Figure 4. As of July 2024, the Gangeo District had 577 facilities for older adults and their children, including 312 daycare centers, 192 primary schools, 35 kindergartens, and 38 senior centers. The areas with the highest concentrations of these facilities were Banghwa 1-dong, Yeomchang-dong, and Balsan 1-dong.
