Systems and methods are provided for analyzing data sets representing consumer and shopper behavior. A data processing system for analyzing sales of a company's consumer packaged goods includes an interface for receiving master and shipment data from sources internal to a company and sources external to the company. Master data and shipment data are stored on a database. A merge and aggregation component operates on shipment and consumption data to create a unique repository of shopper and consumer data. A transcoding and integration component operates on external and internal master data to create a unified master data repository. A set of analytics and reports use unified master data and shipment/consumption data to support Consumer and Shopper Analysis. A sub set of secondary analysis can be performed, capitalizing the Master Data unification and sell-in and sell-out data integration. Consumer and Shopper analysis are performed for clusters of buyers and key performance indicators (KPIs) are calculated for individual customer or groups of customers.
