A movement management system comprising: a plurality of processing units each constituting a corresponding one of a plurality of terminals ; and a management unit adapted to manage movements that are made by mobilities used by a plurality of users each possessing a corresponding one of the terminals , wherein a first processing unit (121-1) that constitutes a first terminal (120-1) possessed by a first user being moving by a mobility , is adapted to broadcast complementary information for complementing a user's position toward one or more terminals being among the terminals and existing around the first terminal (120-1), the complementary information being identification information of the first terminal (120-1) or position information acquired by the first terminal (120-1), a second processing unit (121-2) that constitutes a second terminal (120-2) possessed by a second user being different from the first user and being moving by the mobility , is configured to, upon receipt of the complementary information, transmit the received complementary information to the management unit , the management unit identifying a situation in which the second processing unit (121-2) is configured to receive pair information generated based on the complementary information and the first user and the second user are moving by the mobility , on a basis of the pair information, and the pair information being information indicating that the first user and the second user were at the same place at the same time of day, and the pair information being configured to include identification information of the first user who owns the first terminal (120-1), identification information of the second user who owns the second terminal (120-2), and time information indicating time when the first user and the second user were at the same place. a plurality of processing units each constituting a corresponding one of a plurality of terminals ; and a management unit adapted to manage movements that are made by mobilities used by a plurality of users each possessing a corresponding one of the terminals , wherein a first processing unit (121-1) that constitutes a first terminal (120-1) possessed by a first user being moving by a mobility , is adapted to broadcast complementary information for complementing a user's position toward one or more terminals being among the terminals and existing around the first terminal (120-1), the complementary information being identification information of the first terminal (120-1) or position information acquired by the first terminal (120-1), a second processing unit (121-2) that constitutes a second terminal (120-2) possessed by a second user being different from the first user and being moving by the mobility , is configured to, upon receipt of the complementary information, transmit the received complementary information to the management unit , the management unit identifying a situation in which the second processing unit (121-2) is configured to receive pair information generated based on the complementary information and the first user and the second user are moving by the mobility , on a basis of the pair information, and the pair information being information indicating that the first user and the second user were at the same place at the same time of day, and the pair information being configured to include identification information of the first user who owns the first terminal (120-1), identification information of the second user who owns the second terminal (120-2), and time information indicating time when the first user and the second user were at the same place. <EOS>
