Activity One - What is a population pyramid? What do they show?

Graphical information is key for geographers to help them to represent different ideas and findings. Population pyramids can help us to understand the population structure of a country or region within a country. By analysing them we can infer what possibly may happen in the future and plan for the services and resources that may be required to cope with any population change.


      1. What do population pyramids represent?
      2. Using diagrams describe the three main pyramid shapes.
      3. Give two examples for each of the the three main pyramid shapes.

Activity Two - Making Pyramids

We are now going to be creative by using lego to develop example population pyramids for the different stages of the Demographic Transition Model. Your teacher will be giving you out lego to complete this activity.


      1. Using the lego provided, build a population pyramid for each stage of the Demographic Transition Model.
      2. Draw the models on paper and next to them suggest why you have chosen that shape for the five different stages of the Demographic Transition Model.

Example:

Stage 1 - High Stationary

  • Draw the population pyramid
  • Justify the shape and why it would link to stage 1 of the Demographic Transition Model
