Abstract: A log information obtaining unit which obtains log information; a population information obtaining unit which obtains local population information indicating a population of a local area; a first terminal extraction unit which extracts, based on the log information, a wireless terminal present in the local area in a particular time from among the one or more wireless terminals; a relation parameter deriving unit which derives a relation parameter representing a relation between the number of wireless terminals and the population based on a population of the local area indicated by the local population information and the number of wireless terminals extracted by the first terminal extraction unit; and an estimated value deriving unit which derives an estimated population value from the number of wireless terminals by using the relation parameter are comprised.

Abstract: It is difficult to distinguish facility types. It is difficult to estimate a fluctuating population from the number of communication terminals. A log information obtaining unit which obtains log information in which positional information of a wireless terminal and clock time information at which the positional information is obtained are associated, a population fluctuation pattern determination unit which determines a population fluctuation pattern based on the log information, a type determination unit which determines a type of a facility based on the population fluctuation pattern determined by the population fluctuation pattern determination unit, with reference to basic pattern information indicating a population fluctuation pattern for each facility type, and an estimated value deriving unit which extracts calculation basic information corresponding to the facility type determined by the type determination unit to derive an estimated value of the population movement of the facility are comprised.
