urban geography
Urban Geography
  • How cities function, their internal systems and structures, and the external influences on them.
  • 2 Ways of studying Urban Geography
    • Systems of cities: how cities influence the landscape around them, how they connect to one another, and how they are distributed nationally and globally
    • Internal cities: internal workings of cities, analysis of patterns of land use, racial and ethnic segregation, architecture, intra-city transportation, cycles of construction and development
      • Uses census data, and narrative accounts
urban areas
Urban Areas
  • What’s an “urban” area?
    • Nucleated-clear core area(s), people that live there have non-agricultural jobs
      • Central City
    • Usually surrounded by Suburbs-nucleated spaces that use much land for residences but are not self-sufficient
    • Modern cities and towns so close together they form an urbanized area that is continuously built up landscapes and buildings=Physical city
    • Metropolitan Area
urban hierarchy
Urban Hierarchy
  • Clustered settlements range in size-arranged by complexity of their centralizing functions
    • Smallest to Largest
    • Hamlet-small cluster of farms, and basic services
    • Village-small cluster of homes, and more specialized services
    • Town-larger than village, has more specialized services (bank, schools, library) has a hinterland (area dependent on the town)
    • City-larger population, functional specialization, larger hinterlands, greater centrality, Central Business Districts (CBD)
    • Megalopolis-multiple cities that have grown together-
social life of urban areas
Social Life of Urban Areas
  • Louis Wirth says 3 characteristics of cities that set it apart from rural areas
    • Large Size- too many acquaintances to keep track of everyone’s personal life
      • Many people but don’t know most very well
    • High Density-people have highly specialized jobs, each person in city serves specific purpose-people compete for space (high cost of living), greater differences in rich and poor
    • Social heterogeneity-lots of diversity, freedom and independence not available in rural ares
origin and evolution of cities
Origin and Evolution of Cities
  • Ancient and Early River Civilizations: Formative Era
    • Nile, Mesopotamia, Indus River, China
    • As populations grew, the need for decision makers to distribute food came to be (urban elite)
    • Functions of Ancient Cities:
      • Centers of power-government headquarters
      • Religious centers-priests, temples, shrines
      • Economic centers-markets, merchants, traders
      • Educational centers-educators for the urban elite
urbanization around mediterranean
Urbanization around Mediterranean
  • City-states-self-governing communities plus the surrounding countryside
    • Athens, Sparta, Thebes
    • Rome-becomes an urban empire connected by roadways and waterways
urbanization in china
Urbanization in China
  • Han Dynasty (ruled during Roman Empire) will have largest city in world Chang’an and later Luoyang
    • Located on rivers and near Silk Road trade route
    • Connected by roads, rivers, canals
medieval cities
Medieval cities
  • Roman empire falls and cities take a hit in Europe
    • Venice and Genoa (because of sea trade) remained strong
      • Churches were center of Medieval European cities
  • By 1000 AD the largest cities were in Asia
    • Baghdad, Constantinople (Istanbul), Kyoto, Chang’an, Hangchow.
    • Not until 1800 did Europe have the most populated city in the world-London
pre industrial cities
Pre-industrial Cities
  • Pre-industrial cities were the centers for culture (because industry had not moved in yet!)
    • Primate cities-larger than other cities in the area and representing a national culture
      • Kyoto-primate city for old Japan, Paris, London
      • However! One major difference is that religious buildings dominated landscapes of cities in Middle East, Europe, the Americas but not Africa or East Asia
    • Trade routes and networks determined a cities success and growth-called mercantile city where trade was central to design
industrial cities
Industrial Cities
  • Because of the Industrial Revolution-the manufacturing city emerged-where factories attracted laborers from all over boosting major population growth in urban areas
    • Transportation to and fro and within develops
    • Problems will grow quickly but so will solutions like government intervention and city planning and zoning
world cities and megacities
World Cities and Megacities
  • Manufacturing cities begin to decline as outsourcing and LDC’s are used for that type of labor
  • World Cities include:
    • Largest regional cities: New York, Tokyo, London
    • Second Tier cities: Chicago, Los Angeles, Brussels, Frankfurt, Paris, Zurich, Sao Paolo, Singapore,
    • Third Tier cities: Bangkok, Bombay, Hong Kong, Manila, Osaka, Seoul, Taipei, Buenos Aires, Caracas, Mexico City, Rio de Janeiro, Johannesburg
tiers of world cities
Tiers of World Cities
  • Based on centrality of these services-
    • Business-corporations, banks, insurance companies, stock exchanges, legal and accounting firms, airports, busy harbors, junction of rail and highway networks
    • Consumer-retail business, entertainment and cultural offerings (plays, concerts, restaurants, museums)
    • Public-government headquarters, ambassadors, lobbyists
  • Term created by UN in the 1970’s
  • 25 total megacities=population over 10 million
  • Some include:
    • Tokyo
    • Mexico City
    • Seoul
    • New York City
    • Sao Paulo
    • Mumbai
    • Delhi
    • Shanghai
    • Los Angeles
    • Osaka
functions of cities
Functions of Cities
  • Transportation centers-where major routes converge (roads, railroads, sea traffic, air transport)
  • Special Function Cities-engaged in mining, manufacturing, or recreation
  • Provide goods and services for surrounding area from a central place
economic base of cities
Economic Base of Cities
  • City workers provide services outside city- “export activities” money flows into city-basic sector of a cities economy.
  • Those who produce goods or services for residents of city-non-basic or service sector
  • Some geographers compare number of workers in service and basic sectors-called base ratio of a city
the changing city
The Changing City
  • Borchert’s 4 Stages in the Evolution of American cities:
  • 1. Sail-Wagon Epoch(1790-1830)-technologies determined job opportunities of people entering city
  • 2. Iron Horse Epoch (1830-1870)-railroad technology changed nature of trade and employment
  • 3. Steel-Rail Epoch (1870-1920)-steel industry transformed urban America and job opportunities of workers
  • 4. Auto-Air-Amenity Epoch (1920-1960)- internal combustion engine came to dominate lifestyles, employment, and economic base of cities
models of urban systems
Models of Urban Systems
  • 2 theories of settlement geography-patterns of settlement on earth
    • Rank-Size Rule-true for urbanized cities in the US not in LDC’s or in regions with a dominate primate city-nth largest city will be 1/nth the size of the largest city-2nd largest city will be ½ the size of the first ranked city
    • .
models of urban systems1
Models of Urban Systems
  • Central Place Theory-cities are centers for distribution of goods and services for non-urban populations
    • The landscape is divided into noncompeting market areas—complementary regions where each area and its merchants have a monopoly
    • Market areas form a series of hexagons, no area is un-served, no two centers
    • Central place is at the center of each hexagon, supplies all goods and services to that area
    • Market area is determined by the number of goods and services
    • Some hexagons have smaller ones within it, hierarchy of central places
internal cities
Internal Cities
  • Analyze the internal land space of a city, varying uses
  • Use several factors to analyze
    • Accessiblity
    • High cost of accessible space
    • Transportation
    • Societal and cultural needs
models of urban land use
Models of Urban Land Use
  • Concentric Zone Model-Cites grow outward from a central area (CBD) in a series of concentric rings
  • Sector Model-variant of concentric zone theory, cities develop in sectors not rings from a (CBD)
  • Multiple-Nuclei Model-a city grows from multiple nodes, not just from a (CBD)
patterns of class age gender race and ethnicity
Patterns of class, age, gender, race, and ethnicity
  • Social area analysis-takes census data and overall picture of how various peoples are distributed within an area (city)
  • Most Urban Land Models support the idea that people prefer to live near others with similar characteristics
  • Social Class, Age and Marital Status, Gender (feminization of poverty), Race and Ethnicity clustered into (ghettos) from historical segregation patterns in US
