A computer implemented data processing system for using customer relationship management (CRM) non-exhibiting unique user identifiers in a cellular network for creating geo-statistical representations of the users. The system is arranged to: repeatedly identify all active network-connected devices in each location area using the unique identifier; repeatedly create a table, for all location areas, each table exhibiting: location area identifier, unique user identifier, time of inflow to the location area, time of outflow from the location area; and differentiate table of time N-1 over table of time N thereby detecting inflow and outflow quantities of unique identifiers for each location area; factorizing said difference by the ratio of stationary non-active network-connected device and the total number of network-connected devices; decipher the difference table; analyze the deciphered tables using CRM profiles; and join over time, the deciphered tables with corresponding location area thereby creating at least one GIS data layer.
