Urban
Defined as places of intense social interaction and exchange between strangers
Generally have a dense agglomeration(concentration) of people and activities
Key characteristics are density, proximity and diversity
Urbanization
Population shifting towards the urban areas
De-urbanization is the opposite (rural areas have a population growth)
Metropolitanization
Metropolitan(larger urban areas) growing faster than the smaller urban areas
Suburbanization
Suburban area population increase
Principle Methods used to measure urban places:
1) Population
2) Economic Base
3) Administrative
4) Functional
Note: Basic goods = City forming (agriculture, manufacturing)
Non-Basic goods = city serving (government services)
Urban Geography
Is about,
Understanding the distribution of towns and cities
Accounting for the similarities and differences between them
Main themes :
o System of citiesdistribution of cities & towns
o City as a systeminternal structure of a system
In Urban Geography we,
Recognize and describe the following of the urban area
o Pattern, processes
o Internal structure
Examine how people understand/react to these observed patterns/processes
Seek for how these patterns/processes originated

Approaches to Urban Geography:
EnvironmentalismRelationship between people and their environment
o Site and situational studies
o Urban morphology
o Focuses on production, form and design of urban areas
PositivismHuman behavior is influenced by scientific/universal laws and therefore this
produces observable patterns of urban activity
o 2 main approaches
EcologicalHuman behavior is based on ecological principles.
The most powerful groups get the most advantageous place in a given
space
Example : Burgess Concentric Zone Model
The idea behind this model is that the city grows outward from a central area in a
series of rings. The size of the rings may vary, but the order always remains the same.
This model suggests that the social structure extends outwards from the central
business district, meaning that the lower classes live closer to the city center, while
the upper classes live farther from the city center because they can afford the
commute. Also, as you get further away from the city density decreases. The rent
tends to increase as you get further away from the CBD and residents are more likely
to rent near the center. As you get further away from the CBD it is more likely that
you will find condominiums. However, this model has its weaknesses. It does not take

into account any physical barriers and it does not take into account gentrification-
which may occur in these cities.
Neo-ClassicalDriving force is rationality (or rather, the economic rationality of
humans). Cost-minimization or benefits maximization.
Behavioral and Humanistic
o The difference
BehavioralFocused on decision making, on human behaviour, but seeks
generalizations(for a model-like way)
HumanisticDeeply subjective and complex relations exist between individuals
and groups
StructuralismImportance of social, economic and political structures in society.
o Derived from the work of Karl Marx
o Criticized due to the classes too limiting
Postmodernism Emphasizes that multiple perspectives help understand the urban area better
than having 1 perspective have the say.
o Visible impact seen in Chicago, Toronto and Berlin
o Criticized since there can be endless interpretations for a city

The Origin and Growth of Cities
Why did non-agricultural settlements arise?
Why did they get so geographically concentrated?
Why do some of the urban settlements grow to become larger than other urban settlements?
REASON: Agglomeration Economies
economic benefits due to the concentration of activities in the given space
2 types of Agglomeration Economies
Localization
- Closer to similar firms
- Advantages are : benefit of labor pooling, development of
industries, relative ease of communication and exchange of
supplies, laborers and innovative ideas
Urbanization
- Locating in an urban environment
- (Infrastructure, Information, Economies of scale)
NOTE : Agglomeration Diseconomies
The term 'diseconomies of agglomeration' refers to the opposite case. Additional competition drives
downpricingpower. For example, spatially concentrated growth in automobile-oriented fields may
create problems of crowding and traffic congestion. It is this tension between economies and
diseconomies that allows cities to grow while keeping them from becoming too large.
2 concepts important to understand the development of cities
1) Social SurplusProduction of more basic (city forming) goods than needed for subsistence
2) AgglomerationConcentration of activities/people/networks of relationships in space
A surplus trade and specialization B
Reasons for a social surplus
New technology
Environmental change
Changes in social organization

Early Urban Development
Largest city was Rome
Urbanism spread from Greece
Planned Greece cities had a gridlock pattern
Roman cities had the pattern too, in addition to,
Square/rectangular town perimeter
2 main cross-streets
E-W Decamanus
N-S Cardo
Middle period Urban Development
Slowly growing European cities due to decrease in spatial interaction
Commerce expanded function of cityMercantilism
Cities became industrial centres
Industrial and Post-Industrial Urbanization
Cities became places of population concentration
Cities became more specialized
North American Urbanization
4 phases to the urban development over time
Stage 1: Frontier merchanitilism
Stage 2: Early industrial capitalism (internal structures of cities changed)
Stage 3: National Industrial Capitalism (Central business district in highest cost area)
Stage 4: Mature Industrial Capitalism (Megalopolis emergence)
Main megalopoliss: BosWash
San San (San Diego to San Francisco) & ChiPitts (Chicago to Pittsburgh)

National Urban Systems
Allen Pred - Classified according to interdependence and closure
Settlement patternsoften reflect urban function
Linear Patterntends to follow roads, railroads (easy access to transport themselves, goods)
Clustering Patternemerges from smaller settlements around a central focal point (a resource)
IMPROVES EFFICIENCY!
Uniform/Hierarchical patternmegalopolisa chain of metropolitan areas
City-Size DistributionDistribution of urban regions by population
Has association with: Density of population/activity
Land value/house value
Traffic
Level of social diversity and diversity in services
2 Types of City-Size Distribution
1) ContinuousClear pattern between city size and rank within the urban system
2) DiscontinuousLittle relationship between city size and rank. (maybe due to improper scaling)
Rank-Size Distribution
City Size and Rank are directly linked (in reality many cities dont conform to this, although they are
close)

3) Intermediate or Smaller CityDominant Distribution
Uses of Rank-Size Analysis
1) Analysis of Temporal shifts in the urbanization process2) Comparison of different urban systems
3) Forecasting or planning
CITIES AS CENTRES OF PRODUCTION
In trying to understand the role of cities as centres of production, three questions / issues can be
highlighted:
Why is there a functional specialization among cities (in terms of manufacturing activity)?
Why are larger cities more economically diversified than smaller cities?
Why do some cities have concentrations of corporate headquarters while others do not?
ANSWER: comes from an understanding of how manufacturing (and services) growth is linked to the
growth of cities and the functions performed by them
1) Cities as centres of manufacturing and service delivery
One of the most important components of urban growth
Classifying Manufacturing places:
Components or types of goods: durable, non-durable
Value-added: High-value added (technology), low value added(textiles)
Stage of the manufacturing process: processing raw material, fabrication, assembly

Manufacturing Location
Alfred Webers location Theory least-cost theory of manufacturing location
Firms would locate closer to input market (market oriented)
Firms dependent on specific materials would locate closer to it (materials oriented)
Basically, least cost
Model too simple, idealistic!
Why does manufacturing locate in particular areas?
Needs to be addressed with reference to a broader change in the global economic system

Manufacturing location change after post-Fordism
Production linkages underwent technological and organizational changes
This affected the patterns of production linkages in and between urban systems
Major changes:emergence of flexible production systems
Specialized Industrial Networks
Just-In-Time delivery systems
R&D and HQ favour large, metropolitan areas (skilled labour, network development)
Political changes also affected some changes
Vertical Disintegration: After postFordism, a production process has been broken into several
companies, each doing a limited subset of activities required to produce final product.
Vertical DisintegrationInter-firm linkages
Manual labour (Blue Collar) will be contracted out
Labour Demand and Supply
Labour demand arises due to: Globalization
Industrial restructuring
Technological Change
Labour supply as given by: Population growth and dynamics
Education and Training
Hours of work
Labour market Imbalances
Labour shortage results in: delays in completing projects
Reduced ability to attract investment
Labour surplus results in: underemployment
Underutilization of skills
Involuntary contract/ part-time work

Intra-Urban Employment
Decentralization and clustering of activity/employment
Decentralization:
Major industrial concentrations only appear after major transportation infrastructure
Lower-cost bordering (peripheral) sites are more appealing than central more expensive locations
Home-work becoming more popular
Low-density industrial parks are favoured
ALL LEAD TO PEOPLE MOVING AWAY FROM CITY CORE
Clustering:
Occurs due to intensification of ties between firms
Most seen in central city and older suburbs
Appeals to ventures that can operate in sub-divided/multi storeyed premises
For examplemedia and culture industries in Toronto are suited for this. Also close to the creative
workers
Informal Economy
Underground/Black market
Can distort true market functioning
Many forms
Global Cities
Main sites for capital and investments. Immigrant location. Location of highest-order functions/markets
Globalization = highest-order functions concentrate in only a few key cities. (Leads to international
integration)
Those are GLOBAL CITIES
Command and control centres of the world!

manufacturing
Additional notes :
Gentrificationis a shift in an urban community toward wealthier residents and/or businesses and
increasing property values,[1]
sometimes to the detrimentof the poorer residents of the community.
Gentrification is typically the result of investment in a community by local government, communityactivists, or business groups, and can often spur economic development, attract business, lower crime
rates, and have other benefits to a community. Despite these potential benefits, urban gentrification is
perceived to result inpopulation migration,with poorer residents displaced by wealthier newcomers.
Often old industrial buildings are converted to residences and shops. New businesses, which can afford
increased commercial rent, cater to a more affluent base of consumersfurther increasing the appeal to
higher income migrants and decreasing the accessibility to the poor.
