[dropcap size=small]D[/dropcap]emystifying worldwide population trends since the 1800s sounds like a immensely dry order. Not so when Dr Hans Rosling takes the TEDxSingapore stage with a vivacity that belies his 68 years.

Breaking down thousands of data points into a simple and amusing narrative (interspersed with bawdy jokes), the Time 100 lister delivers in fewer than twenty minutes the answers to these questions:

  • When and why did the average “babies per woman” (an effective metric) dip from 6 to 2?
  • What gives rise to the population crunch?
  • Are there any modern-day policies that Singapore can adopt to combat that trend?
