    • People are forced to move without their consent
  • Reluctant migration
    • When people have a choice but not a desire to move
  • Voluntary migration
    • When people make a positive choice to move

Incentives to Migrate
  • Push Factors
    • Negative conditions at origin
  • Pull Factors
    • Positive attractions of destination
  • Economic Factors
    • Single most important incentive
  • Political Factors
    • War, government oppression
  • Cultural Factors
    • Generally only affect direction of migration/determine end point
  • Amenities
    • Similar to cultural variables, importance increases with immigrant’s wealth and status

Place Utility
  • The value that an individual puts on a given residential site
    • Social, economic, and environmental perceptions

Categories of Migration
  • Step Migration
    • An eventual long-distance migration taken in smaller increments

Patterns of Migration
  • Migration Field
    • An area that dominates a locals in- and out- migration patterns.
    • Tend to be large nations/states and large urban areas
  • Channelized Migration
    • The tendency for migration to flow between areas that are socially and economically allied by past migration patterns, economic trade considerations, or by some other affinity (Chain Migration)
  • Return or Counter-migration
    • The return of migrants to their points of origin or elsewhere
  • Hierarchical Migration
    • The tendency for migrants to move from a smaller to a larger site
  • Urbanization
    • Effects of Post-Industrial Societies on direction

Laws of Migration (Expanded from E.G. Ravenstein – 1885)
  • Most migrants only go a short distance
  • Longer distance migration favors big-city destinations.
  • Large cities are migrant magnets.
  • Most migration proceeds step by step.
  • Most migration is rural to urban.
  • Each migration flow produces a counterflow.
  • Most migrants are adults; families are less likely to make international moves.
  • Most international migrants are young males.
  • Nations with long and/or open borders are attractive to migrants

Industrialization and Urbanization
  • Beginning around 1870 through 1920
  • Macroscale
    • System of new cities arise in core areas
    • Specialize in industrial manufacture
    • Linked by rail lines and water transport
  • Microscale
    • Structure of cities developed around their industrial roll

Models of US Urbanization

Borchert’s Model of Metropolitan Evolution
  • Devised from Adams and Vance
  • Generalization of the growth of the U.S. Urban System
  • Based on key changes in energy and transportation technology (generalized from the US model)
  • Five stage evolutionary process
    • Sail-wagon epoch
      • Primitive overland and water transport
      • Focused on the Northeastern Ports
      • Trade with Europe
    • Iron-horse epoch
      • Early railroads and national transportation system
      • New York as the Primate City
    • Steel rail epoch
      • The Industrial Revolution
      • Improved rail transport
    • Auto-Air-Amenity epoch
      • Introduction of the automobile and air travel
      • Expansion of white-collar service jobs
      • Rise of the suburbs and the Sunbelt (amenities)
    • Satellite-Electric-Jet Propulsion epoch
      • The final epoch favors globally-connected metropolises functioning as international gateways.

The American Manufacturing Belt
  • The Early North American Core
  • Generally a rectangle including southern Canada
    • Boston
    • Milwaukee
    • St. Louis
    • Baltimore

Megalopolitan Growth
  • Driven by advances in transportation
  • Urban decentralization/expanding urban peripheries
  • Atlantic Seaboard Megalopolis
    • 600 mile urban corridor
    • Boston, New York, Philadelphia, Baltimore, and Washington
    • The core of US government, culture, and business
  • Lower Great Lakes
    • Chicago, Detroit, Cleveland, Pittsburg

    • Windsor, Toronto, Montreal, Quebec City

Adam’s Model of Intra-Urban Growth (John S. Adams, 1970)
  • Focused on growth within (intra-) urban areas
  • Dependant upon advances in transportation technology
  • A pattern of outward-areal expansion
  • Four stage development
    • Walking – Horse cart era
    • Electric Streetcar era
    • Recreational auto era
    • Freeway era
  • The final era pushes suburban development more than 30 miles out from the central business district and thus overturns the Primate City Model

Jack Vance’s Urban Realms
  • The single urban structure is transformed into a multi-centered model where several outlying activity centers rival the CBD.
  • Intra-Urban development (micro-scale)

Multiple-Nuclei Model
  • Chauncy D. Harris and Edward L. Ullman – 1945
  • Counters the CBD growth models
  • Cities grow from by spreading from several connected nodes of growth
  • Peripheral expansion lead to eventual coalescence along lines of juncture
  • Developed in Los Angeles

Peripheral Model
  • Attempt to model changes in North American urban areas since 1945
    • Development of suburbia
  • Supplements the previous models
  • Focuses on the periphery of the city instead of the CBD
  • Functions are determined by their relationships with other periphery functions and not the CBD

Changes in Urban FormsPrimarily in North American Cities
  • Automobile
    • Freeway system
    • Replaced mass transit
    • Allowed massive spatial expansion of urban areas
  • Interstate Highway System
    • Expanded urban areas/commuting zones out 20 to 30 miles
    • 50 to 60 miles in Houston
  • Rise in individual home ownership
    • Revolution in mortgage practices by the Federal Government
    • Own free-standing home in suburbs instead of renting within the city
  • Decreased work week
    • More time at home
    • More time to commute

Suburbanization
  • Uniform but spatially discontinuous housing developments beyond the boundaries of the older, central cities
  • Unfocused sprawl since they were not tied to mass-transit routes
    • Automobile
  • Began in late 1940’s to early 1950’s
  • Slowed during the 1970’s and resumed again in the 1980’s
    • Affected by fuel prices
  • Development of the Shopping Mall to provide services to suburban communities
  • Relocation of industry to suburban locations
    • Follow workforce
    • Use of roads meant less dependence upon rail and water transportation
      • Flexible truck transportation
    • Service industries follow Base Sector
  • Edge Cities (Joel Garreau)
    • Development of Suburbs into smaller, independent urban areas surrounding the old city and CBD.
    • It must have more than five million square feet (465,000 m²) of office space. This is enough to house between 20,000 and 50,000 office workers, as many as some traditional downtowns.
    • It must have more than 600,000 square feet (56,000 m²) of retail space, the size of a medium shopping mall. This ensures that the edge city is a center of recreation and commerce as well as office work.
    • It must be characterized by more jobs than bedrooms.
    • It must be perceived by the population as one place.
    • It must have been nothing like a city in 1960.
  • Houston Edge Cities
    • The FM 1960 Area

Cultural Geography of the United States
  • Shaped by the immigrant experience
    • Originally focused no assimilation into the Anglo-Saxon memes
    • Becoming more fragmented in the Post-Industrial landscape
    • Ethnic balkanization or Social Fragmentation
  • Ethnicity
    • National ancestry
    • Plays a key roll in US Geography
    • Euro-Americans (whites) will be less than 50% of the population by 2050
      • Already the case in California and Texas
    • Latino/Hispanic is the largest Ethnicity in the US
  • Mosaic Culture
    • Increasingly heterogeneous complex of separate groups
    • Form along ethnic, racial, economic, age, occupation, and lifestyle

Economic Geography
  • How people earn their living, how livelihood systems vary by area, and how economic activities are spatially interrelated and linked.
  • The study of the location, distribution and spatial organization of economic activities across the Earth

Economic Geography of the United States
  • Categories of Activity
    • Based on increasing complexity and distance from primary subsistence activities
  • Primary Activities (2%)
    • Harvesting or extracting something from the earth
    • Hunting and Gathering, agriculture, mining, fishing, etc…
  • Secondary Activities (Form Utility) (15%)
    • Those activities which add value to goods (and services) by changing their form or combining them into other commodities
    • Manufacturing and processing industries as well as the energy and construction industries
  • Tertiary Activities (18%)
    • Specializations which provide goods and services to the community and the individual
    • Middlepersons between the producer and the consumer
  • Quaternary Activities (55%)
    • The processing and dissemination of information
    • The administration and control the previous levels (management)
  • Quinary Activities (10%)
    • High level decision-making in large organizations
    • Multi-national corporations and large governments

Fuel Resources
  • The basis for American industrialization
  • Fossil Fuels
    • Oil
    • Natural Gas
    • Coal
  • Coal had a major impact on the location and growth of early industrial urban areas in the United States
  • Primary Activity

Agriculture
  • Vast expanses of the American landscape are dominated by agriculture
  • Shift from small family farms to large mechanized/industrial farms
    • Only about 1.5% of the US population is engaged in agriculture
  • Can be modeled using a modified Van Thünen Rings model
    • Core areas are the industrial cores
    • Especially the North East and California
  • Primary Activity

Manufacturing in the United States
  • Access to the Megalopolis market in the East and then the West
  • Proximity to industrial resources
    • Coal
    • Iron ore
  • Economies of Scale
    • Savings accruing from large-scale production
    • Mechanization
    • Assembly lines
    • Specialization
    • Purchases of raw materials in bulk

Industrial Location Models
  • Based on the best combination of the Variable Costs
    • The costs involved in transportation, labor, production, land, etc…
    • Measured against the profit of the item being produced

Least Cost Theories
  • Weberian Analysis (early 1900’s)
    • Transportation Costs
      • Based on a formula for determining the cost of the transportation relative to the raw materials and the finished product
      • Material-oriented (weight loosing) Industry – where the product weighs less than the raw material
        • Located close to source of raw material
      • Market-oriented (weight gaining) Industry – where the product weighs more than the raw material
        • Located close to the market for the product
    • Labor Costs
      • Unskilled labor
        • Common – can be found anywhere
      • Skilled (Deskilled) labor
        • Limited resource – generally found in clusters
        • Silicon valley, around urban areas and universities
    • Agglomeration Costs
      • Clustering of productive activities and people
      • The trend of supporting activities to cluster together to reduce transportation costs and increase access to people
      • Too much competition or over taxation lead to deglomeration
  • Substitution Principle
    • The concept of offsetting (substituting) a high cost activity with a low cost one (i.e. accept higher transportation costs to acquire low labor and agglomeration costs…)
    • Increases the places where industry may be profitably located
  • Spatial Margin of Profitability
    • Expands the substitution principle to create areas where industry can be located.

Transportation Variables
  • Water transportation is cheapest form of transport
  • Railways and highways increase attractiveness of inland points
  • Footloose Activity
    • Where transportation is not a relevant variable
  • Ubiquitous Industries
    • Inseparable from markets and widely distributed
    • Highly perishable commodities for immediate consumption

Post Industrial Revolution
  • High-Tech, white-collar, office based activities
  • Relatively Footloose
  • Technopoles
    • Planned techno-industrial complexes
    • Low density, ultra-modern buildings
  • Based on the internet and other modern communications advances

Post Industrial Location Factors
  • Access to highly skilled labor
    • Urban Areas
    • World Class Research Universities
  • 300 days of sunshine per year
  • Recreational water within 1 hour drive
  • Affordable housing
  • Start up capital ($1 billion)
  • Low risk environment
    • Tax breaks
    • Cooperative state & local governments
    • Lenders
    • Businesses

Maurice Yeates – Canadian Urban Model
  • Model of Urban Spatial Changes (Interurban Model)
  • Cities as points of a network which interact with one another and serve the hinterland – an Interurban Model
  • Three Stages

· Frontier-Staples era

o Shift from a mercantile economy to one oriented by staples (for export)

o Growth of an Industrial Heartland

· Era of Industrial Capitalism

o Increase in manufacturing and tertiary sectors of the economy

o Increase in urbanization

o Beginning of corporate globalization and connections

· Era of Global Capitalism

o Rise in foreign investment

o Movement toward a Post-Industrial Economy (traditional industry is eclipsed by a higher-technology productive complex dominated by services, information-related, and managerial activities)

o Population is majority urban (77%)

Ecumene
  • The inhabitable zone of permanent settlement
  • From the ancient Greeks who used it to define the regions inhabited by humans
