TABULATION SYSTEM

A first tabulation device includes a classification ID acquisition unit that acquires classification IDs of consumers, a purchase ID acquisition unit that acquires purchase IDs of products or services, and an analysis unit that tabulates the classification IDs and the purchase IDs, and analyzes first tabulation information indicating distribution of the classification IDs with respect to the purchase IDs. A second tabulation device includes a classification ID generation unit that generates the classification IDs, based on frequency of a predetermined behavior of the consumers, and a calculation unit that calculates second tabulation information indicating distribution of the frequency of the predetermined behavior with respect to a purchase ID, based on the first tabulation information input from the first tabulation device and the classification IDs. The first tabulation device acquires the second tabulation information, allowing tabulation of purchase data with which a correlation between them can be analyzed while maintaining confidentiality.
