Population Video

    Today in class we watched a video on world population and discussed it. The speaker was Hans Rosling, who teaches global health. In the video, Hans was looking at a graph that we could see as well. The graph showed the life expectancy of countries on the y-axis, and the GDP per Capita on the x-axis. The numbers on the y-axis ranged from 25- 75, and the y-axis $400-$40,000. The graph displayed circles of different colors, each circle representing a country. The colors corresponded with a region such as brown for Europe, red for Asia, green for the Middle East, blue for Sub-Saharan Africa, and yellow for the America's. The graph showed the dots through spans of 100 years. In 1810, almost all the dots were in the bottom left hand corner of the graph signifying the countries as poor and sick. At this time, the life expectancy for almost all the countries (besides the UK and Netherlands), was less than 40 years. As time progresses, many of the African nations remained in this area while the other regions increased and developed. Around 1912, many of the countries fell vertically due to fatalities in WWI. Also, other thing like a flu epidemic in Europe caused the downfall. In 1948, the difference between the countries was wider than ever. In the 1970's, more countries began to catch up and level out to where they are today roughly.
