Abstract
A population estimation serveraccording to an embodiment includes a signal acquisition unitthat acquires a location registration signal periodically transmitted from a mobile terminalcarried by a user, and an estimation unitthat aggregates the acquired location registration signals for each area and for each estimation-unit-period and estimates a population for each area and for each estimation-unit-period based on an aggregation result. When an absent period in which the signal from the mobile terminalstaying in a target area is not acquired occurs after the location registration signal from the mobile terminalis acquired, the estimation unitinterpolates a pseudo signal associated with the mobile terminalin the absent period, and aggregates signals while excluding a location registration signal first transmitted from the mobile terminal after the absent period from an aggregation target.
