Summary by James R. Martin, Ph.D., CMA
Professor Emeritus, University of South Florida
This is an interesting video by Hans Rosling who illustrates the economic development of 200 countries over the last 200 years. Life expectancy is placed on the vertical axis and income per person is represented on the horizontal axis. Life expectancy ranges from 25 years to 75 years while income per person ranges from $400 to $40,000. According to Rosling, the series of graphics illustrated represents 120,000 numbers plotted to show the changes in life expectancy and income per person from 1810 to 2010.
Each country is presented as a circle or bubble, and the size indicates the relative size of the country's population. The colors of the bubbles indicate the country's location. Blue is Africa, Red is Asia, Orange (he calls it brown) is Europe, Yellow is the Americas, and Green is the Mid-east. The 2010 graphic (see above) shows what Rosling refers to as a converging world where all countries are moving up from the condition of poor and sick toward a condition of rich and healthy. A couple of other screen captures show the changes since 1948.
