As an initial study to clarify the impact of flood disasters on population change, this study quantitatively analyzes the impact of flood damage on the rate of change in the social population in all municipalities in Japan in the case of recent flood damage. The variables selected to represent the scale of flood damage were the area inundated, the percentage of households inundated under the floor, inundated above the floor, and the percentage of households totally destroyed or lost in each municipality. The results of both multiple regression and DID analyses showed that the rate of households inundated under the floor, the rate of households inundated above the floor, and the rate of households totally destroyed and lost had a negative impact on the rate of change in the social population (p < 0.05). Floods have a negative impact on social population change at the municipal level in recent flood disasters in Japan, i.e., they reduce the social population.
