Abstract: A system and method that determines building occupancy at a selected site by using geographically based structures to identify potential clients and to analyze aggregate carrier exposure levels at the selected site. This is achieved by using geographically based structures that are formed by geocoding business addresses and by linking all similarly geocoded businesses. Geographically based structures identify building characteristics and occupant related information. Specifically, all business addresses are address standardized, interjected with public protection code information and then geocoded. The geocoding information is used to identify and determine the building's occupancy configuration. For each tenant or occupant of the building, the system will initially display basic information that includes for example, business name, address and whether the business is currently insured by the carrier.
