Day 28- Population Pyramid

Today in class we learned about the population pyramids. Population pyramids are used to judge how man people are in each age group. The population pyramid is separated by five years for each category or section. The population pyramid is also divided into three sections pre reproductive and reproductive and post reproductive ages. The population pyramid can be used multiple ways to judge the future population of a country. A lower age group with a low population usually means that the population is going to go down. countries that look like a triangle are likely to go up and the steeper the quicker the growth. The population pyramid can also be used to judge what economic state a country is in such as country's with fast growing populations are becoming industrialized. Another thing that can be seen in population pyramids is wars because you can see a vast difference between women and men.
