Case Study
Task 1: How does urbanisation happen?
Population
(Millions)
Population growth is the
difference between birth
rate and death rate. When
the birth rate is higher a
population grows, this is
know as natural increase.
When the death rate is
higher, it is known as
natural decrease.

1. Write out the subtitle above.
2. Write down the paragraph in the blue box.
3. Using Figure 13.4 (Page 200) create a mindmap around your building icon to
summarise the four factors that impact
urbanisation.
4. Using the data table, create a graph similar to
the one in Figure 13.5 to compare how two
cities have urbanised.
5. Once you have stuck this graph in (as well as
the data table), answer the following
questions:
1.
2.
In which year did each city grow the most?
How does each city compare? Did they grow at
the same time? Why might they be different
from each other?
Task 2: Where will megacities be in the future?
1.
Write out the subtitle above.
2.
Copy out the information in
the blue box.
3.
Using the textbook glossary
define: Inequality and Urban
Sprawl
4.
Read the extract ‘New
Decade, New Challenges’.
5.
Complete the 6 questions on
that sheet.
6.
Glue this into your book.
7.
Glue the map shown into
your book, create a TEA
paragraph to describe the
predicted distribution of
megacities in 2030.
China has plans to merge cities in the Pearl River Delta to create
one large Megacity, with a population of 120 million. Existing cities
like Hong Kong and Shenzhen would merge to create a city 20x the
size of London.
