Concentric Zone Model of Urban Form
Ch 12 477-480, 482-486
Why do cities look the way they do?
How do urban land uses sort themselves out?
Land use types: categories of urban activities ex industrial, commercial, residential, institutional, open
Central business District (CBD): central nucleus of commercial land uses in city, point of highest
Zone in transition: area mixed commercial, residential, industrial land uses surrounding CBD
So what do our cities look like?
What role does culture play in shaping urban form?
3 classic models fig. 12.2 pg 478
Concentric zone model
-based on early 20 C Chicago
-Ernest Burgess (1925)
-City viewed as series of concentric zones of distinctive neighbourhoods/land uses formed by successive
waves of immigrants arriving in the city
-a socio-ecological model
-spatial pattern of social groups resulted from ‘invasion & succession’ ex groups occupying urban
neighbourhoods change over time as members of one immigrant group replace members of another
immigrants group in a neighbourhood
-ongoing process and given neighbourhood will be occupied by a series of diff imm group over time
where in the city did invasion & succession occur?
-process begins w/ arrival off an imm group in inner city
-this location features lowest cost housing and closest proximity to employment -inner city viewed as ‘reception area’ (point of arrival)
-over time, neighbourhood becomes populated by one dominant ethnic group
-over time, original residents move out of their old neighbourhood into a new one, (thus beginning a
new round of invasion & succession)
-bio analogy (plant communities) leads to city viewed as being comprised of ‘natural areas’
-this research became known as the ‘’Chicago School of Urban Ecology”
CRITICISMS of the Chicago School
-based almost entirely on the city of Chicago
-tends to ignore cultural dimensions of social org
-biologically analogy questioned: are human a
