(France)
- Does Kaclandia have natural resources. If so, where are
they located?

Unit 8 (Urban Geography)
Some basic terms
City: A conglomeration of people and buildings clustered
together to serve as a center of politics, culture, and
economics
Urban: The buildup of the city and surrounding environs
connected to the city (central city and suburbs)
Urbanization: Movement of people from rural to urban
areas—can happen very quickly in the modern world
Global Urban Population
Australia
Where are cities located and why?
Site
• Absolute location
• Static location, often
chosen for trade,
defense, or religion
Situation
• Relative location
• A city’s place in the
region and the world
around it
• Trade area: An
adjacent region within
which a city’s influence
is dominant
Trade Areas
Rank-size rule
• Characteristic of a model urban hierarchy
• The population of the city or town is inversely proportional
to its rank in the hierarchy
For example:
largest city = 12 million
2nd largest = 6 million
3rd largest = 4 million
4th largest = 3 million
Primate city
The leading city of a country, disproportionately larger than
the rest of the cities
Factors affecting primate cities:
- spread of colonialism
- strong centralized government
- economic factors
- rural-urban migration
- efficiency of modern transport
Advantages of primate cities
- Economies of large scale can be achieved because these
cities attract overseas investment and benefits that can
benefit the entire country/state.
- Attractive places of migration.
- Resources, services, and infrastructure available on a
large scale.
Problems faced by primate cities
- housing shortages
- traffic congestion
- crime
- pollution
- increase in land value (unaffordable housing)
- imbalance in development
Primate cities - examples
- France: Paris (popn. 9.6 million)
Marseilles, France’s next largest city (popn. 1.3 million)
- U.K.: London (popn. 7 million)
Next largest city (Birmingham) popn. 1 million.
- South Korea: Seoul (popn. 10 million)
20% of the country’s population.
Countries without primate cities
- India: Most populous city = Mumbai (16 million)
second most populous: Kolkata (13 million)
- China, Canada, Australia, Brazil, U.S.
Central Place Theory (Christaller)
- Predicts how and where central places in the urban
hierarchy (hamlets, villages, towns, and cities) are
functionally and spatially distributed
- Assumes that
– Surface is flat with no physical barriers
– Soil fertility is the same everywhere
– Population and purchasing power are evenly distributed
– Region has uniform transportation network
– From any given place, a good or service could be sold
in all directions out to a certain distance

T = town
V = village
H = hamlet

Organization of Cities and how Cities
Function
Urban morphology: The layout of a city, its physical form
and structure
Functional zonation: The division of the city into certain
regions (zones) for certain functions (purposes)
Zones of a city
Zones
- Central business district (CBD)
- Central City (the CBD + older housing zones)
- Suburb (outlying, functionally uniform zone outside of
the central city)

Modeling the North American city
- Concentric zone model (Ernest Burgess)
- Sector model (Homer Hoyt)
- Multiple-nuclei model (Chauncy Harris and Edward
Ullman)
Classical models of urban structure
Edge cities
Suburban downtowns, often located near key freeway
intersections, including
- Office complexes
- Shopping centers
- Hotels
- Restaurants
- Entertainment facilities
- Sports complexes
Urban Realms model
Each realm a separate
economic, social, and
political entity that is
linked together to form
a larger metropolitan
framework
Satellite cities
Seoul Capital Area
Satellite cities
Example: Seoul Capital Area (Sudogwon)
- Central city is Seoul (“Seoul Special City”)
Satellite cities include:
- Incheon
- Suwon
- Ansan
- Anyang
- Goyang
- Seongnam
- Bucheon
- Yongin
The Seoul Capital Area is the
world’s second largest metropolitan
area
popn. 25,000,000
Cities of periphery and semi-periphery
Latin America
Cities of periphery and semi-periphery
• Griffin-Ford model
• Blend of Latin American
traditions with
globalization
• Disamenity sectors
• Not connected to city services
• May be controlled by gangs
and drug lords
• Industrial park
• Gentrification area
Example: Rio De Janeiro (Brazil)
Industrial park
Cities of periphery and semi-periphery
Subsaharan Africa
De Blij model
- Low levels of urbanization
but rapid growth rates
- European colonial imprint
Nairobi, Kenya
Accra, Ghana
Abidjan, Ivory Coast
Cape Town, South Africa
Satellite township: Cape Town
Cities of periphery and semi-periphery
McGee model
- Colonial port and
surrounding commercial
zone as focal point
Functional zonation – real-life example
Xiamen
How people make cities
Role of powerful social and cultural forces
Periphery and semi-periphery:
- Sharp contrast between rich and poor
- Often lack zoning laws or enforcement of
zoning laws
Making cities in the core (U.S.)
Redlining:
Financial institutions refusing to
lend money in certain
neighborhoods
Blockbusting : Realtors
purposefully selling a home at a
low price to an African American
and then soliciting white residents
to sell their homes at low prices,
to generate “white flight”
Making cities in the core (U.S.)
Gentrification: Individuals buying and rehabilitating
houses, raising the housing value in the neighborhood
Gentrification (Harlem, New York)

Making cities in the core (U.S.)
Commercialization:
City government transforming
a central city to attract residents
and tourists, often in stark contrast
to the rest of the central city
Making cities in the core (U.S.)
Tear-downs: Houses that new owners buy with the
intention of tearing them down to build much larger homes
McMansions: Large homes, often built to the outer limits of
the lot

Making cities in the core (U.S.)
Urban Sprawl: Unrestricted growth of housing, commercial
developments, and roads over large expanses of land, with
little concern for urban planning
Making cities in the core (U.S.)
Urban Sprawl:
New Urbanism
Development, urban revitalization, and suburban reforms
that create walkable neighborhoods with a diversity of
housing and jobs
Concerns:
- Privatization of public spaces
- Failure to address conditions that create social ills of cities
- Countering urban sprawl
New Urbanism
Next Class
- Wrap up Unit 8
- Introduce Unit 9 (Industries and Services)
