Analyzing and Interpreting Population Pyramids & Dependency Ratio
In this lesson, students learn to analyze and interpret the various types and shapes of population pyramids.
Students will begin to see that certain features and shapes are often associated with particular population structures e.g. a wide base indicates a high birth rate, a narrow apex often indicates a high death rate, etc. and also the Demographic Transition Model.
Within the lesson, students will be expected to apply this new knowledge and understanding by analyzing and interpreting a population pyramid from a country of their own choosing.
Students also learn how variations in shape and size also relate to the dependency ratio (the amount of the population that is dependent on the working population) of a particular country. Students practice calculating and interpreting dependency ratio through a number of examples.
These slides can also be printed and displayed within the classroom or given to students as review notes.
