In simple terms, the Central Place Theory states that the central place (city) exists mostly to provide goods and services to the surrounding population. Meaning that the city is the central business district. Additionally, low order goods need to be replenished often, so they can be bought regularly in small stores, in smaller towns (low order settlements). Then high order goods, which are more expensive, less often bought products (such as cars), are sold at fewer business selling these. This is because people need to purchase them less often, and too many establishments selling these goods in one area, would cause them to lack monetarily and ultimately close. That’s also why these high order steel bets would have to be located in large cities, where there is a high number of people to purchase things (I.e. threshold).
In relation to sample findings, it is evident that the base factors of the Central Place Theory, being threshold, range, low order goods/settlements, high order goods/settlements, and hinterland, apply as expected on a smaller (Maine) scale. In our Megalopolis of Portland for example, there are 16 banks. This is a threshold of about 3,420 people per bank to remain in business. As we move from megalopolis, all the way down to hamlet, the number of banks decreases to zero. This is because Dayton (hamlet) only has a population of approximately 488 people. This is below the threshold and thus a bank would not be able to be supported.
Regarding range, it was found that people in the megalopolis of Portland and city of Saco, had so many auto, banking, motel, etc., options that they’d be willing to travel the shortest distance from base for a service. They are surrounded by establishments and services and have no reason to travel further out to the town, village, or hamlet, if that service is even available there. Unfortunately people in the town of Waterboro, village of Arundel, and hamlet of Dayton, have a larger range, as they are forced to travel further distances for certain services. This is because they are unavailable closest to them.
Moving on, low order goods which need frequent replenishing, are located in low order settlements. This could be for example, the milk and general grocery products sold at the Dayton country store, in the hamlet of Dayton. An example of a high order good in a high order settlement, would be an auto mobile bought in the megalopolis of Portland or city of Saco. These high order products are more specialized, and bought less frequently. For these reasons, they need to be located in a megalopolis or city, where there are enough people to meet the threshold, and keep the business open.
Lastly, we refer to Dayton (hamlet) as our hinterland. Dayton is the surrounding area from the major city/metro area. It has a much lower number of residents, and thus less establishments and available services. People also travel a more extensive range to get what they need, and high order goods are rarely available here, compared to their availability in the metro area of Portland.
