How do population pyramids
help us learn about
population?
Population pyramids are used to show information about the age
and gender of people in a specific country.
Male
Female
There is also
a high
Death Rate.
In this
country
there is a
high
Birth Rate
Population in millions
This population pyramid is typical of countries in poorer
parts of the world.
Countries with low average income are called LEDCs.
In some LEDCs,
the government
encourages couples to
have smaller families.
This will result in
a falling
birth rate.
Male
Female
The largest
category of
people were
born about
40 years ago.
In this country
the number of
people in each
age group is
about the same.
Population in millions
In this country there is a low Birth Rate and a
low Death Rate.
This population pyramid is typical of countries in the
richer parts of the world. They are called MEDCs.
Male
In this
country, the
birth rate is
decreasing.
Female
Population in millions
This type of population
pyramid is happening
more and more in
many of the world’s
richer countries.
In the future,
elderly people will make
up the largest section of
the population in this
country.
Male
Female
Population in thousands
This country has a large number
of temporary male workers.
These are men who migrated to
this country to find a job.

Population Pyramids
Population statistics are like crystal balls -when examined closely, they can help
predict a country's future (and give
important clues about the past).

Falling Birth Rate
Which countries have a falling birth rate?
What are they doing about this?
• Japan
• Singapore
• To celebrate Singapore's National Day, Mentos decided to do
something different. We launched a campaign to encourage
every proud, financially secure adult in a stable, committed
long-term relationship to get fresh and 'do their duty' on
National Night to give a patriotic boost to Singapore's
population (which was in a dangerous decline). We wrote a
song, created a video, and the rest, as they say, is history.

Falling Birth Rate
• Demark The birth rate in Denmark is currently
the lowest it’s been in 27 years. Almost 58,000
children were born in 2012, but the present rate
of 1.7 children per family is not enough to
maintain the population.

2. How does this affect global
population growth?

population pyramid and paste it into your PowerPoint document. Add labels to
explain what is shown.
• Go back and repeat for a MEDC (rich) country.
• For a country of your choice, copy and paste the pyramids for 2000, 2025
and 2050.
• Write about what the graphs show and try to give reasons for the patterns.
Explain how the population of this country is changing and say how that could
affect its population.

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)………
