Population and Migration Stuff

     Today in class we were given a worksheet, and we watched a video on some countries' wealth and life expectancy. The man that made the video was named Hans Rosling, and he made the video in 2009 or so. Hans decided to create a chart that shows a country's development with wealth on the x-axis and life expectancy on the y-axis. The lower left of the graph represents the poor and the sick, and the upper right represents the rich and healthy. Each country was represented by a colored circle, and the size was of the country was determined by its population. The graph showed a trend of increasing life expectancy and wealth over a 200ish year period. Towards the year 2009 the United States of America was almost the top country for life expectancy and wealth, but a few European countries had higher numbers. The graph was very well presented, and the information it provided was very interesting.
