Objective 2.4: SWBAT predict population patterns of a country by categorizing its population
pyramid into one of the five stages of the Demographic Transition Model.
Part 1: How can we categorize countries into DTM stages using pop. pyramids?
Directions: Use each country’s population pyramid in 2000 to answer questions 1-4.
Haiti’s Population Pyramid in 2000
1) Are there many births in Haiti in the last 20 years? If
so, this means the country is in DTM stages 1-3.
2) Is the number of births during the last 40 year leveling
out? If so, this means the country is in DTM stages 3-4.
3) Are there many adults over the age of 65? (Is the
population graying?) If so, this means the country is in
DTM stages 4 or 5.
4) Based on your previous three answers, in what stage of the DTM is this country in 2000? Explain
three reasons why you categorized Haiti into the stage of the DTM you chose.
_________________________________________________________________________________________
1) Are there many births in Chile in the last 20 years? If so,
Chile’s Population Pyramid in 2000
this means the country is in DTM stages 1-3.
2) Is the number of births during the last 40 year leveling
out? If so, this means the country is in DTM stages 3-4.
3) Are there many adults over the age of 65? (Is the
population graying?) If so, this means the country is in
DTM stages 4 or 5.
4) Based on your previous three answers, in what stage of
the DTM is this country in 2000? Explain three reasons
why you categorized Chile into the stage of the DTM you
chose.

Denmark’s Population Pyramid 2000
1) Are there many births in Chile in the last 20 years? If
so, this means the country is in DTM stages 1-3.
2) Is the number of births during the last 40 year
leveling out? If so, this means the country is in DTM
stages 3-4.
3) Are there many adults over the age of 65? (Is the
population graying?) If so, this means the country is in
DTM stages 4 or 5.
4) Based on your previous three answers, in what stage
of the DTM is this country in 2000? Explain three
reasons why you categorized Chile into the stage of the
DTM you chose.
****************Stop and get a stamp before moving on to the next population pyramid****************
Directions: Based on your answers above, sketch what a typical population pyramid would look
like for a country in stages 2,3,and 4 of the demographic transition.
1) What happens to the bottom of population pyramids as countries progress through the
Demographic Transition Model?
2) What happens to the tops of population pyramids as countries progress through the Demographic
Transition Model?

Part 2: How can we categorize countries into DTM stages using CBR and CDR data?
Directions: Follow the steps below to determine what stages of the DTM two countries have been in
in the last fifty years.
Step 1: Pick two countries which you will graph their CBR and CDR (Singapore & Nepal OR
Mauritius & Cameroon).
Step 2: On the y-axis of your graph paper you should write “# of births/deaths per 1,000 in a
year” and start with zero. On the x-axis of your graph paper you should write “years” and
start with 1953. Title your chart “CBR/CDR in ___________________________” (In the blank
you should write the names of the two countries you are graphing.
Step 3. Graph the CBR and CDR points on your chart for your first country in a color. Graph
the CBR and CDR points on your chart for your second country in a different color.
Step 4. Answer the questions below for each chart
1. Using your graph, CBR data and CDR data, describe the natural increase rate in each of your two
countries? What has occurred over time? Do you have any guesses as to why?
Country 1:
Country 2:
2. In the year 2003, what stage would you place each of your countries in? Explain three reasons
why you decided on the stage (using data from the graphs/data tables).
Country 1:
Country 2:
