1. Population Distribution
Population Distribution
Lesson starter;

2. We are learning to…
Give examples of countries with a high and countries with a low population density
Describe reasons for the distribution of the world’s population

3. I can…
Find out where densely ad sparsely populated areas are from reading a dot map.
Write a report on the reason for differences in population density

4. On the 31st of October 2011 the world population reached 7 billion – since then it has been increasing by 70 million a year

5. The land area covering the world is 150 million square kilometres (km²)
This means there are, on average, over 46 people per km²

6. Task One Using a copy of the dot map provided along with an atlas:
a) name 4 sparsely populated countries
b) name 4 densely populated countries
c) Using your iPad, look up the actual density of each of the countries you have chosen and put them into a table

7. Links to relevant video/audio clips
Now watch the DVD on world population

8. Reasons for the world’s population distribution
Climate
Soil
Relief
Resources
Communications
Technological development
Economic activities

9. Climate
People prefer to live where there is rain throughout the year – no extremes
Few people live where the climate is hot and wet e.g. Amazon rainforest – this is unhealthy
Russia - cold

10. Soil
Some river valleys are crowded (densely populated) e.g. Ganges, Nile – the soil here is very fertile and so great for growing crops
The river also provides water all year round for crops

11. Relief
People prefer to live in flat, lowland areas – the Himalayas are sparsely populated due to the mountains – this makes building difficult, soils are thin and it is colder as you gain height

12. Resources
People tend to settle in places where there are plenty of resources available
Coal in north-east USA attracted people
Scenery is a natural resource – this attracts tourists e.g. California

13. Communications
People are attracted to areas where there are many roads, railways, airports and ports as these attract industry providing employment opportunities
Remote areas deter people e.g. Ontario Canada

14. Technological Development
Countries that have a high level of technology and well-educated people will be densely populated e.g Japan
Countries with natural resources also need the technology to be able to exploit their resources e.g. Democratic Republic of the Congo

15. Economic Activities
Areas with high industry or services will have greater population densities e.g. south-east Australia
Large numbers of people can be employed in a small area – unlike farming where a great deal of land is required

16. Task Two
Draw a table like the one below and classify the factors affecting population distribution according to human and physical factors
Describe the effect of the following on population distribution:
a) Climate b) Relief c) Natural Resources
Continued on next slide
Human Factors
Physical Factors

17. Task Two Go to page 154 of your Atlas
Using the information there complete the following table:
Rank each of the countries from highest to lowest by:
Population
Size – area
Density
Country
Population
Population Density
Land area
Australia
Bangladesh
France
India
Peru UK

18. We were learning to…
Give examples of countries with a high and countries with a low population density
Describe reasons for the distribution of the world’s population

19. Can I… Locate areas of sparsely and densely populated areas on a map
Write a report on the reason for differences in population density
