WHAT DOES THIS TELL US?• Now that we have analyzed the
pyramid lets work through the questions on the bottom of your sheet together:
• Things to think about:– What affects is this population going to have on the
country?– Which areas of the economy will you need to
change in the next few years?
NOTE: look at the bulges and depression in the pyramid, try and guess which cohort will be dominant and what affect they will have on Canada
