Population Pyramids

In my classroom cupboard I have a large container of jelly babies, used for those times when we need to work out what is population density or to make population pyramids. As a revision technique I will raid my daughters extensive supply of Lego and we will do speed pyramids.

For both Standard Grade and Higher Geography you will need to be able to

• ·         Describe a pyramid
• ·         Compare two pyramids
• ·         Recognise if it is a ELDC or EMDC
• ·         Explain changes over time (Credit and Higher)
• ·         Discuss the difficulties presented by a population pyramid showing an elderly or a youthful population (credit Higher)

Of course Higher answers need to be far more developed than Standard Grade answers, however you should all ensure that you

• ·         Quote figures
• ·         Compare male and female
• ·         Identify the size of the economic dependent population (under 18 over 65)
