Chapter 16.2

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 16.2

Population & 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

Preindustrial to Industrial

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

The Industrial City

Industrial Revolution 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 Ecology

Concentric Zone Model, Sector Model, Multiple Nuclei Model

see 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

Rio De Janeiro: Favela Slums Tour

Favela Slums Tour

Answer the following questions in your journal.

After watching the film, how do you feel about the tourism business in the favelas of Rio?

Do you think that the residents are being helped or taken advantage of? Why?

What similarities can you find with the Dhaka video? How are these cities alike? Different?

How do you think Rio & the favelas specifically, are going to change with the coming of the World Cup in 2014 & the Olympic Games in 2016?
