Correlation Analysis between Median Income level of District and Quality of Medical Service in Seoul, Korea

The importance of medical facilities to citizens is increasing due to frequently occurring pandemics and increased interest in primary health. Although these facilities must be spread widely throughout places to be easily accessed to everyone, it is typically concentrated in central, urban areas. The quality of medical service can be evaluated by the ratio of hospitals of different sizes--clinic, hospital, and territory hospital--since large hospitals offer a higher quality medical care. This research aims to analyze the correlation between each district's median income level in Seoul and medical service quality using a quantitative analysis method based on correlation coefficient analysis. The correlation analysis showed that territory hospitals have a strong correlation with the district's income level, while general hospitals and clinics have a higher correlation with the number of residents and workers.
