What is the Christaller theory?
Walter Christaller developed his “Central Place Theory” in the 1930s. This theory is based on his idea that settlements only existed to function as “central places” to provide services for the surrounding area. This theory is part of the study of urbanization, taking into account the importance of supply and demand.
Why did Christaller use hexagons to illustrate his theory?
The hexagon is ideal because it allows the triangles formed by the central place vertexes to connect, and it represents the assumption that consumers will visit the closest place offering the goods they need.
What shape did christaller represent the market area of a central place?
Both Christaller and Lösch agree that the hexagonal arrangements of market areas around a central place represent the optimal spatial organization for a single good, under the assumption of uniform densities on an unbounded plain with equal access in all directions.
What is K value in geography?
In central places theory, the k value is often used to define the geographical relationship between different orders. With a k=3 relationship, each market area of a higher-order contains three market areas of a lower order.
What is range and threshold of goods and services?
Threshold is the minimum market area needed for goods and services to be economically feasible. Range is the furthest distance consumers will travel to purchase goods or obtain services.
What shape did Christaller represent the market area of a central place?
What is primate city rule?
The law of the primate city was first proposed by the geographer Mark Jefferson in 1939. He defines a primate city as being “at least twice as large as the next largest city and more than twice as significant.”
What is K in central place theory?
What is the difference between range and threshold?
Threshold is the minimum market size (population) needed to support a central place function (service). Range is the maximum distance people are willing to travel to obtain a central place function (service).
What is an example of a primate city?
Mexico City is an example of a primate city because it is disproportionately larger than other Mexican cities and dominates the country.
Is Christaller’s theory still applicable today?
The central-place system of Christaller is applicable partially even to this day in countries of the developing world including India, China and areas where primary occupations predominate. The theory, it is again emphasized, is normative in character.
What did August Lösch argue?
Lösch used modern theoretical and statistical approaches to explore the impact of population change on economic cycles. Initially he believed that falling birth rates were disadvantageous to economic growth, as did most of his contemporaries.
How did Christaller test his theory of community?
He mainly tested the theory in southern Germany and came to the conclusion that people gather together in cities to share goods and ideas and that communities—or central places—exist for purely economic reasons. Before testing his theory, however, Christaller had to first define the central place.
Why did Losch modify Christaller’s central place theory?
In 1954, German economist August Losch modified Christaller’s central place theory because he believed it was too rigid. He thought that Christaller’s model led to patterns where the distribution of goods and the accumulation of profits were based entirely on location.
What are the 3 principles of Christaller’s theory?
Christaller’s theory gives 3 principles which are the marketing principle, transport principle and administrative principle for orderly arrangements and the formation of hierarchy.
What is the Christaller theory of urbanization?
The theory was first developed by the German geographer Walter Christaller in 1933 after he began to recognize the economic relationships between cities and their hinterlands (areas farther away).
