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.

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.
