city
- agglomeration of people and buildings clustered together to serve as center of politics, culture, education, and economics
Urbanization
- began when hunters and gatherers clustered in permanent settlements
- grow crops, art and industries, sacred sites
First Urban Revolution
- first formation of cities
- many out of small agricultural villages

- Andean highlands
Urban Morphology
- city layout
- sizes and shapes of buildings, pathways, infrastructure
Functional Zonation
- division of a city into different regions, (ex: residential or industrial), by purpose (housing, manufacturing, etc)
- helps understand power + wealth distribution, what people value
Site
- absolute location, precise position on Earth
- chosen for advantages in trade or defense, or center for religious practice
Situation
- relative location, place in region, world around it
- can change
Ancient Greece Situation
- network 500+ cities and towns, mainland and islands
- islands and coastal ports for major cities
- connected cities with trade routes
- Athens and Sparta
- mountainous peninsulas, good for trade and defense
- acropolis, high point with temples ex) Parthenon
- Agora, market, center of commercial activity
Rome Situation
- amid small villages and large cities
- extensive transport network
- changed over time
- Rome
- center of Rome Empire -> center of Roman Catholic Church
West Africa pre 1500
- trading cities along Sahara southern margin
- 1350, Timbuktu major city
- Niani, Gao, Zaria
- boat traffic on Niger River
- exchange goods
Trade Areas
- every city has a dominant trade area
- people drawn to it
- hierarchy
- large trade area, within are smaller cities with own trade area
Rank-Size Rule
- German scholar Felix Auerbach suggested, 1913
- linguist George Zipf created equation, 1941
- population of a city will be inversely proportional to its rank in hierarchy
ex) 2nd largest city in area is half population of largest city and 3rd largest will have 1/3 or largest - works in Belgium
- Brian Berry, 1961, found worked in 13 countries
Primate Cities
“a country’s leading city, always disproportionately large and exceptionally expressive of national capacity and feeling” (Mark Jefferson 1939)
- focus economic development and infrastructure in one city, ex) capitals,
- colonization ex) Manila, Philippines, Mexico City
- noncolonization ex) London and Paris
- Brian Berry, 1961, found worked in 15 countries
Central Place Theory
- Walter Christaller (1933)
- predict where central places in urban hierarchy are located
- nested, largest place provide functions to large trade area (hinterland)
- many assumptions
Hexagonal Hinterlands
- series of cities with distinct trade areas spaced regularly from each other would be circles
- inefficient because overlap
- Hexagons most efficient
City Zones
Central Business District: key economic zone
Central City: older part of city surrounding/near CBD
Suburb: outlying, primarily residential area on outskirts
Suburbanization
when lands once outside urban area, farmland or small towns, are transformed into urban areas
- expanded after WWII w/ access to cars and road construction
European City Model
- founding date predicts city layout
- Roman Empire
-sited on prime trade locations (rivers/ports)- narrow and winding streets to trade center
- Middle Ages
- town centers with elaborate church
- town hall
- shops around square
North American City Model
- oldest cities around 400 years old
- built by European migrants -> Europe influence
- changed as access to cars expanded
- Ernest Burgess, 1920s, divided cities to 5 concentric zones
- Homer Hoyt, late 1930s, sector model
- focused on residential patterns - Chauncy Harris & Edward Ullman, 1940s multiple nuclei model
- CBD losing dominant position
Galactic City
qcomplex urban area where functions of city are not centered in one place
ex) LA & Toronto
- post industrial economies
Edge Cities
large urban areas with extensive space for offices and retail buisnesses
- on outskirts of major cities
ex) Irvine California & Tysons Corner Virginia
Latin American City Model
- Ernst Griffin and Larry Ford created model
- blend South American culture with global economy
- central plaza = CBD
- CBD = traditional market sector + modern high-rise sector
- three radial sectors: commercial spine +2 squatter settlements (favelas/barrios)
Disamenity sector: poorest areas, not connected to services, controlled by gangs
African City Model
- predate European colonialism
- H.J. de Blij created model
- three CBDs
- traditional (commerce on street/stalls), single-story buildings, traditional architecture
- informal/periodic market zone, open-air
- colonial, highrises - rings of slums
Southeast Asian City Model
- T.G. McGee, 1967, created model
- focal point is old colonial port zone, combined w/ commercial district around it
- no formal CBD, clustered in:
- colonial port zone
- gov. zone
- western commercial zone
- immigrant CBD, Chinese merchants
- market gardening zone on outskirts
Southeast Asian City Model
- T.G. McGee, 1967, created model
- focal point is old colonial port zone, combined w/ commercial district around it
- no formal CBD, clustered in:
- colonial port zone
- gov. zone
- western commercial zone
- immigrant CBD, Chinese merchants
- market gardening zone on outskirts
Zoning Laws
- divide cities
- designate kinds of development in diff. zones
- global periphery, lower income, lack zoning laws
ex) Hyderabad, India - Accra, Ghana - Manila, Phillipines
Redlining
- before Civil Rights Movement (1960s)
- Home Owners’ Loan Corporation + banks
- red lines on map around. “risky” neighborhoods
- based on race, ethnic neighborhoods in red lines
- refuse loans to those buying in redlined areas
- became illegal in 1968 Fair Housing Act
Blockbusting
- purposely sell house at low price in white neighborhood to black buyer
- make white residents sell homes due to neighborhood “going downhill”
-> white flight: movement of whites from city to suburbs
Gentrification
- renewal or rebuilding of lower-income neighborhoods to middle/upper class
- near centers of many cities
- began in places with tight housing market + defined central-city neighborhoods ex) Chicago, Portland
- slowed 1990s, but growing again
- increases housing prices
- displaces lower-income residents
Teardowns
- suburban gentrification
- houses people buy in suburbs w/ intents of tearing down for larger home
- new larger homes sometimes called McMansions
- changes landscape + increase house values
Urban Sprawl
- stricted growth of housing, commercial dev., and roads over large expanses of land
ex) strip malls, big-box, stores, chain restaurants, huge intersections, numerous housing dev., over many acres - automobile era
New Urbanism
- countering urban sprawl
- development, urban revitalization, and suburban reforms that create walkable neighborhoods w/ house and job diversity
- Congress for the New Urbanism (1993)
- reduce traffic time, increase affordable houses
- criticized by some
Gated Communities
- fenced-in neighborhoods with controlled access gates for people + cars
- often have security
- maintain/increase house values
- late 1980s to early 1990s
- some see as new form of segregation
Node
- place where action and interaction occur
- world cities are connected to other world cities
- measured by influence
- act as forces shaping globalization
Megacities
- measured by number of residents, population
- large city with 10 million +
- difficult to provide services to that many
- center of gravity for migrants
- large slum devs.
Hutment factories
- centers of entrepreneurship where slum residents sew, recycle, build, or trade/sell
