The problems of local government for the human damage assessment in earthquake are : 1. The regional distribution of population cannot be identified exactly, because it differs with too many factors such as season, time and etc. And we think regional population structure is one of those important factors. 2. Main issue in regional plan of disaster prevention is to select the most hazardous district in the city and to take suitable countermeasure ; therefore selecting suitable parameters to distinguish the difference of human damage in districts is needed. In this paper, we proposed a solution of the above problem.
