POPULATION PYRAMIDS
(Age Structure Diagrams)
A population pyramid is easier to read if you see
that it’s really just two combined bar graphs.
Age Structure Diagram
(Population Pyramid)
But the
populations of
most
developing
countries keep
growing
rapidly. Most
developing
countries have
a high birth
rate.

Mali, Africa, has a high birth rate.
Countries with high birth rates have problems
associated with fast population growth.
They may not have enough jobs, housing,
education, or medical care for all their
citizens. Poor countries often have a
high birth rate.
oldest
youngest
Many wealthy
countries have
populations that are
growing very slowly,
holding steady, or
even shrinking.
Hong Kong has a low birth rate. Countries
with low birth rates have many elderly people.
What challenges might a country face when they
have a growing population of elderly people?

Australia almost has a steady birth rate.
Countries close to steady birth rates usually
avoid population-related problems.
This United States population pyramid shows
a “baby boom.” How can the problems of a
“baby boom” be similar to that of an aging
population?

As baby boomers reach school age, classes are
overcrowded and new schools have to be built.
What will be done with those schools after the
boomers are no longer students?

At this point, have students
create their own population
pyramids of the U.S. and
Mexico, using the blank
population pyramid charts
provided in this lesson,.
Population pyramids offer
windows into what’s happening
& what has happened.
These can be used throughout
the year.
