1. Why do people move to megacities?
Now!
Why might a city feel they need to make the changes that Shanghai did?

2. Key question / Learning outcomes
Section A: Urban Issues and Challenges
Why do people move to megacities?
Key idea
Specification content
A growing percentage of the world’s population lives in urban areas.
Factors affecting the rate of urbanization- migration (push-pull theory), natural increase.
The emergence of megacities.
LEARNING OUTCOME…
Define urbanisation.
Describe and Explain population trends.
Explain changing rates of urbanisation across the globe.

3. How many megacities were there in the world at the time of the film?
Learning Link
Think back to Andrew Marr’s Megacities we watched at the start of this unit.
How many megacities were there in the world at the time of the film?
Now that you know about HICs, NEEs and LICs, which category do the megacities from the video fall under?

4. New Information/Activity
Why do cities grow?
Rural-Urban Migration: the movement of people from the countryside into towns and cities.
Natural Increase: where the birth rate is higher than the death rate.
So if more people are being born than are dying, the population will increase.
Push Factor: Reasons why people want to leave somewhere (in this case, the countryside).
Pull Factor: Reasons why people want to move to somewhere else (in this case, the city).
When people migrate, they do so for a variety of push and pull factors.

5. New Information/Activity
You will now have to decide whether the following statements are push or pull factors. You will write your answers on your mini whiteboards.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

6. Farming is hard and poorly paid.1
Farming is hard and
poorly paid.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

7. Desertification and soil2
Desertification and soil
erosion make farming
difficult.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

8. There are more well-paid3
There are more well-paid
jobs.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

9. Drought and other climate4
Drought and other climate
hazards reduce crop
yields.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

10. A higher standard of living5
A higher standard of living
is possible.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

11. They already have friends and6
They already have friends and
family living there.
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

12. Answers Push; economic; LICs, NEEs, HICs
Push; environmental, economic; LICs, NEEs
Pull; economic; NEEs, HICs
Pull; social; LICs, NEEs, HICs
Good: Push or Pull?
Better: Social (people), economic (money), or environmental (nature)?
Best: More likely to be a factor in an HIC, NEE or LIC?

13. New Information/Activity
Look at some of the other push and pull factors involved in urbanisation by marking your worksheet in the following ways
Good: Highlight which factors are push and which are pull.
Better: Label each factor as economic (EC), social (S), or environmental (EN).
Best: Label each factor by where it is more likely to occur: HICs, NEEs, LICs.

14. Describe the distribution of the world’s megacities.

Reflection
Describe the distribution of the world’s megacities.
“Describe the distribution”= where in the world can you find…? (But being VERY specific)
