Population Pyramids part 2

In today's Honor's Human Geography class with Mr. Schick we watched a video on population pyramids and why they are so important to us as a society. The video explains what population pyramids are, what they are used for, and why they are important. After we watched that video, we watched a second video by Hans Rosling. He showed his data in an animation type of graph. The x-axis was life expectancy and the y-axis was average annual income. He then had all the different regions in a specific color while each dot was its own country. In the bottom left of the graph all the countries there could be classified as poor and sick. While in the top right the countries could be classified as rich and healthy. In 1810 you can see that almost every country starts out in the poor and sick category. This is because these countries are pre-industrialized countries meaning that they haven't industrialized yet. You then see during industrialization some of these countries rise in the graph and flourish in health and money. After watching the video the bell rang and ended class.
