Comprehension check video

Today in human geography class on November 16th we watched a video on population and migration   and we did a worksheet which was a statistical Analysis/ comprehension check and we watched a video about a man who taught global health ad what it was all about. I found it very interesting because it was cool to learn about the history about the Industrial revolution in the late 1700s and how the history was which each country that was affected and in the video the countries were color coded with a specific color to represent them. The video also mentioned that the chart the guy had made represented income on the x-axis and life span or life expectancy on the y-axis. The chart was mainly focused on the poor and sick people at the time he was teaching the course and it was represented on the lower part of the chart. The upper part of the chart was represented with the rich and healthy people in the world and how easy they had it compared to the poor and sick people who had no money to support them selves and how hard it was to get by day by day not knowing what to expect.
