Central Place Theory
Transcript of Central Place Theory
Period 5 > Hexagons are used to show the location of market areas
> Problem with circles: Circles leave gaps or overlap one another. This shows that there are people living outside of the market area of some services when that isn't true.
> Problem with squares: Although there aren't any gaps, the sides of the squares aren't equidistant from the center. This shows that the distance to the market in the center of the circle would be further away from some areas than from others. > There are fewer larger settlements (high-order areas), which are distributed further apart from each other. These provide services that have larger ranges and thresholds.
> Smaller settlements (low-order areas) have small ranges, thresholds, and market areas. They provide local consumers services, like fast food restaurants and convenience stores. Market Area of a Service > "A central place is a market center for the exchange of goods and services by people attracted from the surrounding area."
> Central places have to compete against each other to sell their goods and services to the area around them.
> The higher the threshold and range of a product, the further a customer will have to travel to purchase it.
> Department stores or large shopping malls are usually spread further apart rather than just in the local vicinity. What is the Central Place Theory? Characteristics High-Order & Low-Order Settlements Hierarchy > Developed by a German geographer named Walter
Christaller in 1933 based on his studies in
> This model helps explain where the most
profitable lands are located > Boundaries can be interrupted by physical features, like bodies of water or mountain ranges. There are four levels of market area: city, town, village, and hamlet; with city being the largest and hamlet being the smallest. In Christaller's original study, he identified seven settlement sizes: regional capital city, provincial head capital, small state capital, district city country seat, township center, and market hamlet.
