Population pyramids

Today we went over the test and also talked about P O P U L A T I O N P Y R A M I D S. Population pyramids help us see the growth of a population, and tell us about other things that happened to a population. an example being Russia after world war 2 when a large population of men died. (due to war). https://www.populationpyramid.net/ also shows us the estimated population in oncoming years. another example being in 2100 the United States of America will have a population of 450,384,822. We watched a ted talk on this as well, talking about population pyramids. Other than that I did a good job on my test scoring a 96 out of 100. population pyramids also tell us about countries well being. As a developing country, the pyramid will actually look like a pyramid. and a developed country will look rectangular.
