Centripetal or Centrifugal?

Push and pull factors causing inward and outward movement of

populations

This can help to explain people’s choice of movement

CORE LINK!

Centripetal Forces

• These are associated with the movement of people into the urban area.

• For each of the following centripetal forces, explain the process that encourages this inward movement.

Centripetal Forces – Rural to urban migration

Gentrification

Urban renewal

Centrifugal Forces –Urban sprawl

Suburbanisation

Counter-urbanisation

Task

• Suggest why processes of population movement are likely to vary between cities.

• In other words… why do some cities see centripetal movement, and others see centrifugal movement?

• Use any examples you know to backup your points.

Is there a link between natural increase in the population size, and the number of urban areas?

• Firstly, discuss what factors might influence a country to have a high (or low) natural increase in its population size.

• Then consider what indicators you could use to exemplify this.

• Finally, try to find a graphic that shows the link between natural increase and urban populations.

GENERAL PATTERN?

SO, WHAT IS A DRIVING INFLUENCE IN THE GROWTH OF GLOBAL CITIES?

Link it all together

• Look at some of the reasons why cities began to expand and spring up around the world, from 1955 onwards.

• What were the driving forces?
