The core-periphery model was developed in 1963 by John Friedmann and it identifies the spatical distances from the core. The core-periphery model works on many scales, from towns and cities, to a global scale.

Facts about Brazil:

Capital City: Brasilia

It contains the second longest river in the world.

It contains the largest rainforest in the world

Population: 185 million

Area: 3.2 million sq. miles

A great example of core and periphery is Brazil with the ‘golden triangle’ at its core and the Amazon being its main peripheral area. Within cities like Sao Paulo, Belo Horizonte and Prio 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 like:

  • Overcrowding
  • Lack of housing
  • And sometimes the formation of favelas

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.

There are reasons why the core area developed and not other areas. Sau Paulo for example developed because of it coffee industry, Rio de Janeiro developed because it’s a port and became big with imports and exports. Similarly the peripheral areas haven’t developed because of the lack of accessibility to the area or lacking in resources, human and phyical.
