Hans Roslings Video

Hans video is about the Demographic Transition and how it changes over time acoording to the nation and its culture. Rosling’s review of the past 200 years leaves me rather optimistic about the years ahead. As he has outlined elsewhere, there are serious problems facing us in regards to exponential population growth and global health. Yet there are also solutions to humanity’s grand challenges of poverty, health, energy, etc. Demonstrations like this one could help broader audiences not only grasp the seriousness of the situation, but have hope that we can improve the world with out policies and technologies. As Rosling shows, the world is always changing and our beliefs must change with it. Perhaps colorful graphs and exciting lectures will help us reshape how we think of the world. At the very least they’ll change the way we think of statistics.
