Abstract: The systems and methods described herein can index the economic activity in a trade area of a location by identifying a set of data concerning the economic activity of a plurality of locations and storing it with the associated geographic position of each of the locations. A geographic trade area is then determined for each of the locations, using either a pre-set area defined as a radius from the location or through input by a user. The database is queried to identify all of the locations within the trade area of the subject location. The economic activity associated with the locations is aggregated and compared across time periods to create the index of the economic activity within the subject location's trade area. The economic activity from these locations may also be weighted by any number of factors, including distance from the subject location, and type of retailer.
