The purpose of this research is to understand the distribution of population around the nuclear plant 1 and plant 2 both in the daytime and in the nighttime by analyzing the global spatial autocorrelation and the local spatial autocorrelation. According to the survey, we found that a cluster of population existing in some areas around the nuclear plant 1 and plant 2. Therefore, we display the visualization of these clustering areas by GIS and local spatial autocorrelation in order to understand the exact distribution of population in that region.
