Transcript of Peripheral Model

Peripheral Model
Wealthy VS. Poor
Inner City:
Apartments very close to the center of the city
Neighborhoods designated for low-income families
Edge City:
Apartments very close to the center of the edge city
Basic Layout
periphery model
consists of an inner city surrounded by suburban residential and business areas tied together by a beltway of ring road.
By: Midori Salgado and Kayla Snare
This is a Peripheral Model of a city
In the Peripheral Model, the CBD has much less influence as the entertainment businesses and services relocate into the Suburban Residential Areas
The next closest thing to the inner city in the Peripheral Model is the
suburban/residential area.
A huge piece of an urban area is the housing and where people live outside the city.
Although a majority of a city's main attractions and jobs are at the center, most people don't actually live there.
A large percentage of people living in suburban areas surrounding the city commute to the center every day for work.
Suburbia is a very important piece of the model because it is where most of the population resides and therefore takes up a lot of space in an urban area.
Other City Complexes
Every city has essential
buildings such as banks, airports, malls, city halls, etc.
Where it all started
What does the Peripheral Model showcase?
Density Gradient
density gradient
is the change in population density as you move farther from the inner city.
Originally, population density dropped exponentially as you left the city and entered the suburbs. Now, suburbs are attracting more people, and the population of inner cities is dropping.

Commute/Modern Transportation, New families, Cheaper cost of living, edge cities, etc.
Urban Sprawl
[Sub]Urban Sprawl
is the uncontrolled expansion of urban areas.
Services might set up shop near residencies and slowly attract more developing businesses looking for relatively isolated land. These patterns of development result in inefficient land use and urban sprawl.
Suburban Segregation
is the segregation of groups based on income.
Neighborhoods are built and intended for a certain class, and the people in that community disprove of anyone with a lower income residing there.
Notice the inner city surrounded by a majority of SRAs, all surrounded by a
Beltway or Ring Road
Inner City:
Houses and residencies further from the center of the city
Neighborhoods desginated for high-income families
Edge City:
Houses and residencies further from the center of the edge city
These can result in the developing of edge cities or nuclei as stated in the Multiple Nuclei Model.
An Introduction into Human Geography by James M. Rubenstein



Entertainment businesses and services have begun to follow people moving into SRAs, which creates suburban sprawl and continues suburbanization
In conclusion, the
Peripheral Model
is just one of many ways an urban area can be represented in an effective way and we hope you learned something new today!
Real Life Example?
The model was created by
Chauncey Harris
to showcase the effects of suburbanization in an urban city.
Harris and Ullman's
multiple nuclei model also helps to explain the efffects of suburbanization and edge cities in an urban area.

Our nation's captial is a prime example of the peripheral model in action.
Following the model, Washington DC has a strong central area with political buildings and historics and as you venture out towards the edges of the city, you begin to see residencies and smaller businesses etc.
