Today in class we looked at population pyramids again yay. We looked at how different country's population pyramids and why. There are three different stages in a country that directly affect population. The first stage is pre industrialization in this stage the population grows rapidly and the age expectancy is low. Mainly because the are few jobs so what why not have a few kids. The healthcare in this stage is quite bad which explains the low level of life expectancy. The next stage is industrialized when the are still a lot of kids but the life expectancy gets higher do to better healthcare. The last stage is post industry when there are less kids because of people not having kids do to them going and starting their careers.
