Population pyramid

Today in class we talked about population pyramids. These are like bar graphs. but put on their sides. They are used to show population at ages at a rate on a graph. There are three types of them. A tree, box, and cup. A tree is a developing nation with not a lot of old people and a lot of kids. A box is a developed nation that has a solid base of young people as well as a girthy top of old folks. Finally, a cup is a place where there are more old people than young. The first and last are not good situations because there is a lack of work force and leadership. The middle one is the best because it is set up for all tasks. We also had a shadow in our class named Kyle. He was homeschooled is entire life, and is looking for a school to play football and meet new people. I personally like him because I have met him before and we are friends. He is an athlete that I can relate to. In the end, I enjoyed this class and am intrigued by the population pyramids.
