How do population pyramids help us
learn about population?
Population pyramids are used to show information about the age and gender (sex) of people in a specific country.
Male Female
Population in millions
In this country
there is a high Birth
Rate
There is also a high
Death Rate.
Which country do you think this pyramid represents? Why?
In some LEDCs the government is
encouraging couples to have smaller families. This means the birth
rate has fallen.
Male Female
Population in millions
In this country the number of people in each age group is
about the same.
The largest category of people were born about 40 years
ago.
In this country there is a low Birth Rate and a low Death Rate.
Which country does this pyramid represent? Why do you think this?
Population in millions
Male Female
In this country the birth rate is decreasing.
In the future the elderly people will make up the
largest section of the population in this
country.
This is happening more and more in
many of the world’s richer
countries.
Male Female
Population in thousands
This country has a large number of temporary workers. These are people who
migrate here especially to find a job.Why does this evidence suggest this?
Population pyramid for Mozambique.
Population pyramid for Iceland.
Compare & ContrastWhat type of countries are these?Evidence?
What happens next…?
What is likely to happen to Japan’s population in the future?
Why does this matter?

Challenge Yourself
When you have finished;
Find out some background information on each country and add this to your presentation.
Concentrate on facts and figures which you can use to compare the countries such as % of the children at school, type of jobs available, how rich or poor (GDP per capita.)………
Population Structure
• The population pyramid is a good way to ‘predict’ countries future changes or needs.
• We can predict these by looking at the dependency ratio of different age groups
