Urban Patterns and Processes Lec #3 Flashcards
What is the order of a good?
how that good is ranked via consumption, expertise, etc
What is a low order good?
inexpensive, consumed frequently, available nearby, less likely to travel for
ex) cookie
What is a high order good?
expensive, consumed rarely, not easily available, people willing to travel further
What is range?
How far a consumer will travel to purchase a good (consumer is at centre)
What is a threshold?
The distance defining the minimum number of consumers required by a business (business at centre)
Consumers need to be in _________ to get goods and businesses want to be in _________ to get customers.
threshold, range
What pattern of settlement did consumer behaviour lead to?
Hexagons
- the idea is that consumers will travel to the nearest business within their range. With overlapping thresholds, actual consumer behaviour forms hexagonal shape.
What is central place theory?
- distance between small towns was closer than distance between large towns
- services available in small towns differ from large towns, small towns have mostly low-order goods, large towns have a mix of low and high order goods.
Explains how cities are set up - created by Walter Christaller
What are limitations of the central place model?
Assumes “empty” space
Simplified economics
What about transportation and administration –> lack of sufficent services in low income areas
What is market area?
the area in which its consumers are located
What are urban hierarchies? How are they created?
Differentiation among human settlement and economic activities
They are created by production in an urban system.
What is an urban system?
A set of cities in a single market economy (horizontal exchange, not vertical) that have an economic hierarchy caused by consumption and production
What is the size/service pyramid?
High level cities in the urban hierarchy have few urban places and large amounts of economic, administrative, and social activity
Low level cities in the urban hierachy have many urban places but a small amount of activties
What is the Rank-size rule?
The population of a city equals the population of the largest city divided by the rank of the city.
Pr=P1/r
In a group of 20 cities where the largest population is 10 000 000, what is the population of the second largest city?
10 000 000/2= 5 000 000
What is the relationship in a mature city of rank size rule?
a linear relationship
