Who was John FriedmanWho was John FriedmanJohn Friedman is one of the
pioneering urban theorists of the late twentieth century. He founded the Graduate School of Architecture and Planning at UCLA in the late 1960. He is famous for his analysis of world city formation.

CORE-PERIPHERY MODELCORE-PERIPHERY MODELThe core-periphery model of
development, tries to represent the emergence of an urban system in four major stages which works equally with the development of transportation.
From an initial state of inequalities, disparities are reduced and a functionally integrated urban system emerges.

It helps explain why some inner city areas enjoy considerable prosperity, whilst others display all the signs of urban deprivation and poverty.
The core-periphery model works on many scales, from towns and cities, to a global scale.

John Friedman proposed that the world can be divided into four types of regions. These are;◦Core regions◦Upward transition regions◦Resource frontier regions◦Downward transition regions
![Page 7: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/7.jpg)
Core regionsCore regions
• Core regions refer to centers, which are usually metropolitan. These centers typically have a high potential for innovation (improvement) and growth.
Example:• São Paulo in Brazil

Upward transition regionsUpward transition regions
• Upward transition regions are areas of growth, which spread over small centers, rather than at the core.
![Page 9: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/9.jpg)
Resource frontier regionResource frontier region
• This refers to a newly colonized region at the periphery of a country, which is brought into production for the first time.

Downward transition Downward transition regionsregions• These are regions on the
periphery characterized by depleted resources, low agricultural productivity or by outdated industry.
• A current Caribbean example of this is in Haiti.

Services, investment and jobs are concentrated in the core Central Business District (CBD).
Accessible inner city areas may benefit from a trickle down of wealth from the core.
For example, in some areas there may be a through-flow of office workers to the inner city seeking low-price lunchtime meals.
The core also provides work for inner city residents.

Less accessible inner city areas may experience a backwash effect, with the little investment that occurs in the inner city becoming concentrated close to the CBD, widening the poverty-wealth gap.
This is illustrated in the diagram below, a reversal of the core-periphery model.

STAGES OF DEVELOPMENTSTAGES OF DEVELOPMENT
According to John Friedman’s theory, there are four stages of development. These include;
1.Stage 1 - Pre-industrial2.Stage 2 - Transitional3.Stage 3 - Industrial4.Stage 4 - Post-industrial
![Page 18: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/18.jpg)
STAGE 1STAGE 1
The pre-industrial stage. This refers to the agricultural /
primary sector of society, which is characterized by economies limited to a small area and a small scale settlement structure.
Each aspect of the pre-industrial society is fairly isolated, dispersed and characterized by low mobility.
![Page 19: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/19.jpg)
STAGE 2STAGE 2
The transitional stage. The concentration of the economy
in the core begins. This is as a result of capital accumulation and industrial growth.
A dominant centre emerges within an urban system to become its growth pole. Trade and mobility increase, but within a pattern dominated by the core even if overall mobility remains low.
![Page 20: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/20.jpg)
Among the numerous examples of such a phase is the early industrialization of Great Britain in the late 18th century or the beginning of the colonial incorporation of regions in Latin America, Africa or Asia.

STAGE 3STAGE 3
The Industrial stage. Through a process or economic
growth and diffusion other growth centres appear. The main reason for deconcentration is the increasing production costs (mainly labour and land) in the core area.
This diffusion is linked with increased interactions between elements of the urban system and the construction of transport infrastructures.
![Page 22: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/22.jpg)
STAGE 4STAGE 4
The Post-industrial stage. The urban system becomes fully
integrated and inequalities are reduced significantly.
The distribution of economic activities creates a specialization and a division of labour linked with intense flows along high capacity transport corridors.

CASE STUDY - BRAZIL.
![Page 26: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/26.jpg)
A great example of core and periphery is Brazil with the 'golden triangle' at its core and the Amazon being its main peripheral area.
There are reasons why the core area is developed and not other areas.
Sau Paulo developed because of it coffee industry.
Rio de Janeiro developed because it's a port and became big with imports and exports.
In contrast, the peripheral areas haven't developed because of the lack of accessibility to the area or a lack in human and physical resources
![Page 27: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/27.jpg)
Within cities like Sao Paulo, Belo Horizonte and Rio de Janeiro, overheating has become a serious problem. Large amounts of people from the peripheral areas within Brazil move to the core area. This causes many problems such as:
Overcrowding. Lack of housing. And sometimes the formation of
favelas.
![Page 28: FRIEDMAN’S CORE PERIPHERY MODEL](https://reader030.fdocuments.net/reader030/viewer/2022032903/6240c403f6aa8f49a93daf33/html5/thumbnails/28.jpg)
As well as the problems this causes to the cities, the peripheral areas are also effected.
A large majority of the people who are moving into the core area are young adults. The peripheral areas are then therefore loosing young, potentially educated, adults.

CONCLUSIONCONCLUSION
The core-periphery model was developed in 1963 by John Friedmann and it identifies the spatical distances from the core.
The model attempts to represent the emergence of an urban system in four major stages.
It helps explain why some inner city areas enjoy considerable prosperity, whilst others display signs of urban deprivation and poverty.
