In this powerful visualisation, first broadcast on BBC Four in 2010, the late Swedish physician and public speaker Hans Rosling tracks 200 countries across two centuries, plotting life expectancy against income.

What emerges is a world that has changed far more dramatically—and unevenly—than labels like "developed" and "developing" suggest.

These two measures obviously aren't the whole story. But as a four-minute snapshot of how human life has changed, it’s incredibly effective.
