Answer:
market area
Step-by-step explanation:
A market area is actually a geographical area from which consumers will come to use or consume your service. Each market area has a certain range which measures the actual distance that consumers are willing to move or travel to use or consume your service.
For certain industries, specially grocery stores or supermarkets, market area is very important, because consumers are generally not willing to travel for two hours in order to get to a Walmart. That is why malls, supermarkets, pharmacies, grocery stores are distributed all around a city. This market area varies depending on the type of product, since consumers from all around the world travel to go to Disneyland.
