Abstract
An object is to provide a population distribution aggregation calculation device which can calculate a population distribution of high accuracy. A population distribution aggregation calculation device includes a narrow-area mesh group management unitconfigured to generate wide-area mesh data by acquiring the number of user terminals positioned in each predefined wide-area mesh using approximate positional information of a user terminal, and to generate narrow-area mesh data by acquiring the number of user terminals positioned in each of a plurality of narrow-area meshes obtained by dividing a wide-area mesh by a predetermined geographic resolution for each predetermined positional information acquisition pattern using detailed positional information stored in the positioning data accumulation unit, a reliability evaluation unitconfigured to calculate reliability of narrow-area mesh data for each positional information acquisition pattern on the basis of wide-area mesh data and narrow-area mesh data, and a population distribution estimation unitconfigured to estimate the number of terminals in a narrow-area mesh on the basis of the narrow-area mesh data and the wide-area mesh data according to the reliability.
