Population pyramid

How do population pyramids
help us learn about
population?
Let’s see some examples.

Population pyramids are used to show information about the age
and gender of people in a specific country.
FOR EXAMPLE:
Male Female
Population
(in millions)
In this
country
there is a
high Birth
Rate
There is
also a high
Death Rate.
This population pyramid is typical of countries
in poorer parts of the world (LEDCs.)

In some LEDCs the
government is encouraging
couples to have smaller
families. This means the
birth rate has fallen.
POPULATION PYRAMID OF BANGLADESH (year 2000)

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.
This population pyramid is typical of countries
in the richer parts of the world (MEDCs.)
ANOTHER EXAMPLE

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.
