Location is a key factor in urban growth
• Climate, topography, and
waterways help determine
urban growth.
• Many well-located cities are
linchpins in trading networks.
– Resources from
agricultural regions enter
cities.
– Products are shipped to
distant markets.
U.S. Urban Growth Stages
Industrialization has driven urbanization
• Since 1950, urban populations have quadrupled.
– Due to a growing human population and
increased movement to cities
– By 2050, urban populations will grow by 94%.
• In developed nations, urbanization has slowed.
– Suburbs: the smaller communities that ring
cities
• Developing nations are urbanizing rapidly.
– People are searching for jobs and urban
lifestyles.
Major Cities of the World
Today, for the first time ever, over ½ of the world’s
population lives in urban areas.
Intraregional Migrations in U.S.
For about 100 years the U.S. population has been moving out of the city
centers to the suburbs of the cities: suburbanization and
counterurbanization
Developed Countries:
suburbanization
 automobiles and
roads
‘American Dream’
 better services
 lower taxes

Interregional Migrations
U.S. population has been moving Westward and Southward
 Gold Rush (1849) and Donner Party just the most dramatic
examples of hardship.
– Wells, Pumps, Aqueducts, Mosquito Control and Air Conditioning have
allowed this move which otherwise would be impossible.
 Loss of Industrial Jobs in east compliments increase in Sunbelt (AZ,
FL, CA, etc.) service sector (biotech, communications).

Rank-Size Rule
Rank-Size Rule: n thlargest settlement is
generally 1/n the
population of the
largest settlement. In
other words, 2nd
largest is 1/2 the size
of largest. Works best
in most developed
countries that have full
distribution of services.
Primate City Rule
If the largest settlement in a country has more than twice
the number as the second ranking city, it’s called
primate. These cities tend to represent the perceived
culture of the country and have a disproportionate
influence on the country.

Megalopolis
Illustrates the difference
between strict city proper
definitions and broader
urban agglomerations.
To define urbanized areas,
the U.S. Census Bureau
uses the term Metropolitan
Statistical Area (MSA) or
Consolidated MSA (CMSA) if
two of them overlap.
Today’s urban centers are unprecedented
• Today, 20 cities are home to more than 10 million residents.
– Tokyo, Japan has 35 million residents.
– New York City has 18.7 million residents.
• But the majority of urban dwellers live in smaller cities.

Urbanization in developing countries
• Most fast-growing cities are in developing
countries.
– Less need for farm labor due to
industrialization
– Wars, conflict, and ecological degradation are
driving people to cities.
• Many of these cities face overcrowding,
pollution, and poverty.
– Their economic growth does not match their
population growth.
Suburbanization:
in the wealthiest countries people have moved to suburbs
• By the mid-1900s, the U.S. and other countries had
accumulated more people than jobs.
– Unemployment caused poverty and crime.
– Affluent city dwellers moved to cleaner, lesscrowded suburbs.
• Suburbs had advantages of space and privacy.
– More space, better economic conditions, cheaper
real estate, less crime, and better schools
• But natural space decreases with increasing suburbs.
– People have to drive everywhere, increasing traffic
congestion.
People in suburbs take up more space
On average in the U.S., each suburban resident takes
up 11 times as much space than a city dweller.

School Segregation
Sprawl
• Houses and roads supplant more than 1 million
ha (2.5 million acres) of U.S. land per year.
• Sprawl: the spread of low-density urban or
suburban development outward from an urban
center
– Physical spread of development is greater
than the rate of population growth.
– Phoenix, Arizona’s population grew 12 times
larger between 1950 and 2002, while its land
area grew 27 times larger.
Several types of development lead to sprawl
Sprawl has several causes
• Human population growth
• Rising per capita land consumption: more land per
person
– People like their space and privacy: “The American
Dream?”
– Interstate highways make it easier to commute.
– Technologies (telecommunications and the Internet)
free businesses from dependence on the centralized
infrastructure, and workers can live wherever they
desire.
• Economists, politicians, and city boosters have
encouraged it.
– “Growth is good”
– Increases a community’s economic well-being and
political power
What is wrong with sprawl?
• Transportation: people are forced to drive cars
– Pressure to own cars and drive greater
distances
– Increases dependence on non-renewable
petroleum
– Increases stress, injuries, deaths.
• Pollution from sprawl’s effects on transportation
– Carbon dioxide, nitrogen- and sulfurcontaining air pollutants
– Motor oil and road salt from roads and parking
lots
What else is wrong with sprawl?
• Health: promotes physical inactivity because driving
cars replaces walking
– Increases obesity and high blood pressure
• Land use: less land is left as forests, fields, farmland,
or ranchland
– Loss of ecosystem services, recreation, aesthetic
beauty, wildlife habitat
• Economics: drains tax dollars from communities
– Money goes to new communities for roads, water
and sewer systems, electricity, police and fire
services, schools in new developments
Phoenix, Arizona
City and regional planning
• City (urban) planning: the professional pursuit that attempts
to design cities to maximize their efficiency, functionality, and
beauty
– Planners advise policymakers on development options,
transportation needs, public parks, etc.
• City planning grew throughout 20th century
– Expanding urban populations, inner cities decayed, and
wealthier residents fled to suburbs
• Regional planning: deals with same issues as city planning,
but with broader geographic scales that must coordinate with
multiple municipal governments
Zoning
• Zoning: the practice of classifying areas for different
types of development and land use
– Homeowners and businesses know what can
and cannot be located nearby.
• Opponents say that zoning’s government restriction
violates individual freedoms.
• Proponents say government can set limits for the
good of the community.
Urban growth boundaries (UGBs)
• Limits sprawl: keeps growth in existing urbanized
areas
– Revitalize downtowns
– Protect farms, forests, and their industries
– Ensure urban dwellers some access to open
space
– May reduce infrastructure costs
• Disadvantages:
– Increases housing prices within their boundaries
– Restricts development outside UGB
– Increases the density of new housing inside the
UGB
• Relentless population growth may thwart even the
best anti-sprawl efforts.

Building Better Cities
What kinds of cultural values are reflected in this
landscape?
Smart growth
• Smart growth: urban growth boundaries and other
land use policies to control growth
• Proponents promote:
– Rejuvenating older existing communities
– Building “up, not out”
– Focusing development in existing areas
– Favoring multistory shop-houses and high-rises
New urbanism
• New urbanism: neighborhoods are designed on
a walkable scale
– Homes, businesses, and schools are close
together
• Functional neighborhoods in which most of a
family’s needs can be met without using a car
• Zoning rules must cooperate with new urbanism.
– Denser development must be allowed.
Mass transportation
• A key in improvement of quality of urban life
– Public buses
– Trains and subways
– Light rail: smaller rail systems powered by electricity
• Cheaper, more energy efficient, and cleaner
• Traffic congestion is eased.
– Traffic jams cost the U.S. economy $74 billion yearly.
– The average American household spends over $8000
a year on automobile-related expenses! Median
household income in 2009 was below $50,000.
Parks and open spaces are key elements
• City dwellers want escape
from noise, commotion, and
stress.
• Natural lands, public parks,
and open space provide
greenery, scenic beauty,
freedom, and recreation.
– Protect ecological
processes
• Parks originated in America
at the end of the 19th century.
• Even small spaces can make
a big difference.
– Playgrounds, community
gardens, greenways

Changes in Cities in LDCs
Populations of cities in the less developed world have been
surging: urbanization, migration, natural increase
Urbanization in
Developing Countries
 driven by changes in
global economy that make
farming more challenging
 the poor live in the
suburbs, rich live in CBD
 cities struggle to provide
jobs and housing
 services overtaxed
 squatter settlements
common
 crime on the rise

Europe versus U.S. Cities: Sprawl
European cities, including this hypothetical U.K. example, tend
to restrict suburban development, thereby concentrating new
development in and around existing concentrations. This leaves
large rings of open space, so-called greenbelts.
What are the social costs of sprawl?

Complex street patterns - prior to automobile, weird angles
Plazas and Squares - from Greek, Roman, Medieval
High density and compact form - wall around city or low-growth zoning
Low skylines - many built before elevators, others required cathedral or
monument to be highest structure
Lively downtowns - center of social life, not just office work
Neighborhood stability - Europeans moved less frequently than we do.
Scars of War - many wars , many cities originally defensive
Symbolism - gothic cathedrals, palaces, and castles
Municipal Socialism - many residents live in buildings that are owned by city
gov’t. Some of these are massive housing projects, others small scale apartment
buildings.
