In order to decrease of inequalitie against insurance system between households, the insurance system from receive to collection was considered by the group division according to damage amount of the inundation inside levee. The distribution between annual average damage and the number of households was obtained by flood economic damage through flood analysis and flood control economic research, in Tokushima prefecture. This distribution quantifies such inequalitie, when the insurance system through receive and collection are determined. When the groups is divided according to the damage amount, the insurance system through the group division contributes to less inequalitie. This less inequalitie occurred both in determining the insurance maximum receive and in changing the insurance collection.
