What is Urbanization? The growth of a central city and its suburbs The “Nail House” in Chongqing, China
Global population now 54% urban, 46% rural
Percent Urban Population Developed world is most urbanized, but developing world is urbanizing at the fastest pace.
Urban Growth 2002-2015
World’s Largest Urban Agglomerations (Urban Areas)
What Is A City? A node in a circulation system of people, resources, goods, services and ideas. There is no set size for a city - definitions vary from country to country and state to state.
Terms Urban: town or city, high density of human-made structures Micropolitan: urban area with population of 10,000-49,000 (U.S.) Metropolitan: densely populated urban core & its surrounding areas sharing industry, infrastructure & housing Exurban: prosperous communities beyond the suburbs that are commuter towns for an urban area
Metropolitan and Micropolitan Statistical Areas
Metropolitan Areas Micropolitan Areas
1st Urban Revolution Corresponds to 1st Ag Revolution Dates? Crops, domesticated animals Food surpluses - not everyone has to be a farmer People no longer have to move in search of food Rise of specialization & social classes Populations grow - cities emerge
Hearths of Urbanization
Mesopotamia - 3500 BCE
2nd Urban Revolution Corresponds to Industrial Revolution & 2nd Ag Revolution Dates? Mechanization - greater ag surpluses Industrialization Large scale movement of people to cities to work in factories
Site and Situation Affect Whether Or Not Cities Grow and Prosper Situation: characteristics of the relative location of a city Accessibility Connectivity Proximity to resources Site: characteristics of the absolute location of a city Landforms Climate Vegetation Water supply Soil quality Minerals Wildlife
Today, situation is the most important factor in the growth of a city.
Megacities: Population = 10 Million +
World City: Important Node in Global Economic System
The World is Spiky
A leading city that is disproportionately larger than the other cities in the country. London, UK Mexico City, Mexico Paris, France Primate City
Rank-Size Rule Population of city is inversely proportional to its rank in the urban hierarchy. For example: Largest city = Population 12 million 2nd largest = Population 6 million 3rd largest = Population 4 million 4th largest = Population 3 million Does not work in regions with primate cities
