4. Describe the SHAPE of your pyramids At the minute we are not saying WHY they look like that, just simply WHAT they look like. Use these words in your description: base, apex, curved, concave, convex, wide, narrow, beehive, steep sides

5. What does the shape tell us about each country’s demographics? BASE WIDTH – APEX WIDTH – CONCAVE – CONVEX – CUMULATIVE HEIGHT –

6. How can we use Population Pyramids to predict the future? At what ages to do people start and finish being ‘economically active’?

7. Demographic Transition Model Draw the outline shape of the Population Pyramids for countries in Stages 1 - 5 of the DTM.
