population pyramid

-
Today in class we learned about the population pyramid. It is a type of chart that measures and shows the percentage and how many of a people in a certain age group and gender group there are in the world or in a country. This could be useful if you wanted to see how many 10-14 year old's there are in the U.S. This chart is separated into three sections young/kids, middle age, and old age. We also got our population tests back I got a 87 on it I am pretty happy with that grade. I only got four wrong which is not bad.
