Population Pyramid

In class, we watched the population pyramid video again and talked about it. A population pyramid measures the percentage of people living in a country according to gender and age. If a pyramid is wide at the bottom and narrow at the top, the population is growing rapidly and people are having kids at a very fast pace. Later on, the same pyramid will be wider at the top, and narrower at the bottom because all the kids from the baby boom aren't having as many kids when they get older. There are a large amount of them but not as many of their children. The last thing we talked about was the 3 eras that countries have been through. There was pre-industrialization , industrialization, and post-industiralization.
