WarmUp: Journal Entry In your journals, make a list of
characteristics of urban or city life. Next, suggest some of the reasons
that people might choose to live in cities.
Finally, suggest some problems that might be associated with rapid population growth in cities.
Chapter 16.2Population & Urbanization
Objectives Explain how cities evolved & why
urbanization is such a recent event.
Identify the models that have been proposed to explain the structure of cities & summarize the theories that have been put forth to explain city life.
Megacities: Urbanization in Dhaka, Bangladesh
PBS News Hour: Megacities• Consider the elements of this clip when
going over the notes.
Urbanization the concentration of populations in cities
The Evolution of the City

The Preindustrial City cities arose about
6,000 years ago populations limited by
inefficient agricultural techniques
crowded, lacked sanitation
no designated “downtown”
built around extended family

led to urbanization covers greater area,
much larger population influence of family
lessened 1790: 5% of population
in cities 1860: 20% of
population in cities Today: 75% in urban
areas
Urban EcologyConcentric Zone Model, Sector Model,
Multiple Nuclei Modelsee page 425
Urban Ecology examines the relationship between people & the urban environment
Concentric Zone Model typical city
spreads outward from the center, resulting in a series of circles or zones
Sector Model city grows in
wedge-shaped sectors outward from the center to the edges of the city
transportation determines land use
Multiple Nuclei Model city develops
around several centers of activity, or “nuclei,” devoted to specialized land use• example: stores
grouped together, car dealerships, etc.
Urban Ecology Models: Critique describe ideal types of cities
• do not account for urban sprawl, reverse migration, or urban reclamation
Examining City Life
Urban Anomie Theory, Compositional Theory, Subcultural Theory
Urban Anomie Theory the city is an
anonymous & unfriendly place & living there caries serious negative consequences
characterized by impersonal secondary groups
Compositional Theory greater diversity
of city residents leads to greater variety of lifestyles• race, ethnicity,
gender, age, education, income, occupation
Subcultural Theory people can find
others with similar interests in diverse cities
some people form close ties and subcultures
