Analyzing Age-Structure Diagrams
Name:
For each of the countries, you need to analyze their age structure diagrams to determine what is happening to
their populations. Compare the 2000 data with the projection for the year 2050. Provide the populations for each
year and provide a sketch of the age-structure diagram. Then decide if the population is expanding (rapid or
slow growth), stable (zero growth) or declining (negative growth). Circle the correct answer.

Create hypothetical histogram on the next page
 Briefly explain a situation that has taken place in the past or hypothetically could take place in
the future- use your imagination.
 Design a histogram that best fits the scenario you have described. Age groups should be in
increments of 5 years- make sure to label males/females, population numbers etc.
 Identify at least 3 characteristics/abnormalities found in your histogram and explain how your
scenario correlates to those characteristics/abnormalities.
 For example, your histogram could be box-like which correlates to a scenario of stable
population. BE AS CREATIVE AS YOU LIKE!! Make sure your STORY MATCHES YOUR
HISTOGRAM AND EXPLANATIONS!
 You will present you histogram to the class
