12POSTULATES or OUTCOMESThen . . .
- There will be a regular spatial order in the
number of central places of different population
sizes. - Few large places
- Many small places
- There will be a regular spatial order in the
spacing of central places of different population
sizes. - Large places relatively farther apart
- Small places relatively closer together

14Higher-Order FunctionsHigher-Order Central Places
- Provision of higher-order goods and services
- Trade in goods and services that are more
valuable and infrequently demanded - Because the goods and services are more valuable,
people are willing to travel farther to shop. - Higher-order goods and services are available in
higher-order central places.
15Lower-Order FunctionsLower-Order Central Places
- Provision of lower-order goods and services
- Trade in goods and services that are less
valuable and frequently demanded. - Because the goods and services are less valuable,
people are willing to travel only short distances
to shop. - Lower-order goods and services are available in
lower-order central places.

willing to travel for the service- How many
customers a service needs
20Each central place function has a
- Threshold the minimum number of people needed to
support a central place function - With fewer customers a store cannot afford to
stay in business.
- Range the maximum distance beyond which a
person will not travel to purchase a good or
service - Beyond a certain distance people cannot afford
the travel costs.

What is? vs. What should be?
26A WALK ACROSS FRANCE by Miles Morland
We never knew whether or not a village would
have a shop or a restaurant, but we were
developing a system. We used to look up the
population on the map. The IGN puts this in tiny
figures next to the village name. Our system
went like this
27Village Population What to Expect
300 One all-purpose shop
500 Shop and café Occasional pharmacy
700 2 shops, 2 restaurants, garage, pharmacy, maison de la presse
200 Forget it.

- Half-way between Washington and Richmond?
- Fredericksburg
- Half-way between Richmond and Norfolk?
- Williamsburg
- Half-way between Washington and Baltimore?
- Columbia
36Why do we not ever see a perfect central place
hierarchy?
- Physical geography is important! Topography and
hydrography interfere. - Consumer behavior is determined by more than
economic considerations. - The automobile has made long-distance travel
popular (cheap and easy). - People make multiple-purpose shopping trips,
often bypassing the smallest places. - The Internet has made it unnecessary to have
customers nearby.
