Briefly discuss the range of a service
What will be an ideal response?
Answer: The range of a service is the maximum distance people are willing to travel to use that service. The range is the radius of the circle drawn to delineate that service's market area. The market area of every service varies. To determine the extent of a market area, geographers need two pieces of information about a service, its range and its threshold.
People are willing to go only a short distance for everyday consumer services, like groceries and pharmacies. But they will travel a long distance for other services, such as a major league baseball game or a concert. Thus a convenience store has a small range, whereas a stadium has a large range. If firms at other locations compete by providing the service, the range must be modified. As a rule, people tend to go to the nearest available service: someone in the mood for a McDonald's hamburger is likely to go to the nearest McDonald's. Therefore, the range of a service must be determined from the radius of a circle that is irregularly shaped rather than perfectly round. The irregularly shaped circle takes in the territory for which the proposed site is closer than the competitors' sites.
The range must be modified further because most people think of distance in terms of time, rather than in terms of a linear measure like kilometers or miles. If you ask people how far they are willing to travel to a restaurant or a baseball game, they are more likely to answer in minutes or hours than in distance.
