Estimation of the cause of low health level in Ulsan Metropolitan City: Focusing on the movement of the address of the deceased

Abstract

Objective: In this study, it was assumed that the cause of the low health level problem represented by the high mortality rate in Ulsan was due to the change of address before the death of the deceased. We analyzed how many people moved to Ulsan before death by analyzing the address movement of the deceased from 2014 to 2018, and compared the results with those of Gwangju and Daejeon, which have similar population sizes.Methods: The socio-demographic characteristics of the deceased in Ulsan were summarized by year, and the proportions of the address of the deceased one year before and five years before the death was compared with those of Gwangju and Daejeon. In addition, a chi-square analysis was performed to determine whether there is a difference in the previous address according to the regions.Results: In the case of the address of the deceased one year before and five years before death in Ulsan, the proportions of areas other than Ulsan were about 4% and about 13%, respectively, indicating that the figures did not change significantly. When comparing and analyzing the addresses of the deceased in three metropolitan cities before death, the proportion of Ulsan for outside of Ulsan was generally about 1%p higher than those of Gwangju and Daejeon, but the level was significantly different.Conclusion: It was difficult to accept the hypothesis that one of the reasons for the low level of health in Ulsan was the change of address before death of the deceased. Other causes of Ulsan’s low health level need to be explored further.
