Definition
Reilly’s Law of Retail Gravitation is a principle in retail marketing and economic geography that suggests the attraction of retail trade areas is proportionate to the size of the retail center and inversely proportional to the distance people must travel to it. Named after William J. Reilly, this law helps explain customer behavior in terms of retail shopping patterns. The essential idea is that larger retail centers will pull in a greater number of customers from nearby smaller retail outlets and even from a greater distance.
Examples
-
Suburban Shopping Malls: A large shopping mall located in the suburbs may attract shoppers from the urban center as well as adjacent towns. For instance, a suburban mall with a variety of large anchor stores, food courts, and entertainment venues will draw more shoppers compared to a small plaza with limited retail options.
-
Outlet Centers: An outlet shopping center, although located in a rural area, attracts customers from neighboring urban and suburban areas because of the variety and discounted prices of brand-name goods.
FAQs
Q: How can businesses use Reilly’s Law to their advantage?
