CPT – CRQ Practice
What do you see?
First: underline, circle, and brainstorm
1. Define the following terms and how they apply to
central place theory:
(a) range of good or service
(b) threshold population
(c) hierarchy of market centers
2. Explain how the diagram at the left demonstrates the
hierarchical relationship, characterized in central place
theory, between the settlements shown on the map.

1. Define the following terms and how they apply to central
place theory:
(a) range of good or service
(b) threshold population
(c) hierarchy of market centers
1. Definitions and description of how a term
applies to central place theory. 1 point for each
definition, 1 point for how the term applies to CPT.
(A) Range of good or service
• definition: the distance people will go for a
good or service
• application: larger settlements are farther
apart and offer services with high ranges while
smaller settlements, which are nearer to each
other, offer only services with small ranges.
(B) threshold population
• Definition: the minimum number of people
needed in a settlement before a good or
service will appear there
• Application: the larger settlements have all of
the goods and services available in smaller
settlements, plus additional services which
have higher thresholds and only appear in
them when they reach a certain population
(C) hierarchy of market centers
(C) hierarchy of market centers
• Definition: settlements range in size from large
cities – with many services, to smaller villages
and towns - with some services, to small hamlets
– which offer few services .
• Application: there are fewer large settlements
(cities) and they are more widely dispersed, then
medium settlements (towns) which occur more
frequently, and finally small settlements
(hamlets) which are numerous and closer
together
2. Explain how the diagram at the left demonstrates the
hierarchical relationship, characterized in central place theory,
between the settlements shown on the map.

This is worth 4 points.
Discuss what you see on the map / diagram.
How many cities, towns and hamlets?
Which would have the most services?
Which would have the largest range?
What types of services would be offered in the
cities, towns, and hamlets?
• Gravity model
2. Explain how the diagram at the left demonstrates the
hierarchical relationship, characterized in central place theory,
between the settlements shown on the map.
• On the map you can see that there is only one
city, which represents the top of the hierarchy
of settlements in central place theory. It would
have the MOST services because of its larger
population and some of its services would
have the largest RANGE, attracting people
from the entire region shown. It would offer
both high order and low order goods and
services.
2. Explain how the diagram at the left demonstrates the
hierarchical relationship, characterized in central place theory,
between the settlements shown on the map.
• There are four medium-sized settlements (towns)
which are in turn surrounded by 12 smaller
villages.
• These would have fewer services and attract
customers only from their immediate areas.
• These would offer mainly low order goods and
services.
• The goods and services in these towns and
hamlets, would require a lower threshold, and
have a much smaller range.
• Based on the gravity model, people in towns
and hamlets closest the city, will be attracted
to the city because of its intervening
opportunities, transferability and
complementarity.
• The city has a larger population, and the
availability of high order goods and services.
