Population Pyramids part 2

Today in class we talked more about population pyramids. We looked at different pyramids for different cities in the United States and we talked about why we think that the population and the shape is like the way it is. For example for Manhattan, New York it was mostly populated in the 2 twenties and thirties, it is like that because Manhattan is the place for business, fashion, and getting your name known. We also looked at the whole world and we looked at what is like and what it will look like in the future. We also looked at different countries population pyramid and looked at the past and the future. When we saw the different pyramids we said if it was the Christmas tree, the box, or the cup then we talked about why we thought it was the it was.
