I saw this link to a TED talk as I was looking for population projections for China and the US. It is from a professor and co-creator of GAP minder (recently bought by Google I think). Not too many numbers but lots of animations of health, income by region for different countries. Starts by showing the people have out dated view of life expectances and family size. It is very interesting visually. I also think it is a powerful teaching tool.

Fact: Mexico and the US had almost identical birth rates in 2008. If you did not know that your knowledge is outdated.
