• What we mean by the base of the PP and what it
  was like in 2006 (narrow, medium, wide)
• What we mean by the top of the PP and what it was
  like in 2006 (narrow, medium, wide)
• What we mean by the middle of the PP and what it
  was like in 2006 (narrow, medium, wide)
• Which generation do you think has had the most
