Group Task Using the 2006 Population Pyramid (blue with generation names), identify: 1.What we mean by the base of the PP and what it was like in 2006 (narrow, medium, wide) 2.What we mean by the top of the PP and what it was like in 2006 (narrow, medium, wide) 3.What we mean by the middle of the PP and what it was like in 2006 (narrow, medium, wide) 4.Which generation do you think has had the most impact on Canada as it has gone through its life stages (children, teenagers, adults, seniors)? Why?
