Population Pyramids

Today in class, on November 1, we had a shortened class because of mass that was going to take place third mod. We did not start taking notes right away in class so it felt very short. We started talking about the three different types of population pyramids. The three types were the Christmas tree, the box, and the cup. Each version was a general graph of the population growth or decline in different countries. The Christmas tree had many kids and the number of people decreased with age. This is for developing countries for the most part like Nambia. The box was mostly equal in population for all ages and represented developed nations like the United States. Last, the cup had fewer children than elderly people. This is also for a developed nation like Japan, for example, but the population of this type of country would be declining. This is true because the generation of fewer kids will grow old enough to have kids of their own but there will still not be many of them.
