POPULATION
Understanding the population of a country not only tells us how many people live in an area.
We can also begin to look at how many young and old people there are
We can also look at home many men and women there are
This allows us to work out a lot of information about each country.

TASK
L
ook at your labels
T
hey will refer to different sections of your population
pyramid
S
tick them on and draw an arrow to that section
LABELSThe birth rate tells us how
many children per 1000 are born each year. The higher
the birth rate, the lower developed the country is
The number of people between 16-65 tells us how many people are working,
which means they pay taxes to the government
The number of people in the 0-16 category tells us how many people are in schools
The number of people over 65 tells us how many people
are retired.
The higher the age categories the better the life expectancy, which shows the
country is well developed
If a bar is much shorter than you would expect, this says
that something has happened, such as war or
disease. The more wars and diseases tells us that a
country is less developed.
The death rate is the number of people, per 1000, who die each year. The higher this
number, the lower developed the country is
