Abstract: A demand prediction device and a demand prediction method capable of performing demand prediction with higher accuracy. A demand prediction server includes a data acquisition unit acquiring estimated population information that indicates population estimated in a predetermined area, a spatial weighing unit acquiring relative distance information that indicates a distance between a position of a prediction reference area included in the predetermined area and a position of a prediction target area for which the number of demands is to be predicted with the prediction reference area as a reference, and a regression analysis unit and a demand prediction unit for, by performing regression analysis using the estimated population information acquired by the data acquisition unit and a residual based on the relative distance information acquired by the spatial weighing unit, predicting the number of demands in the prediction target area.
