CIA World Fact-book question review

Yesterday we did an assignment where we had to write interesting facts about 5 countries and talking about them. I talked about different countries like Chad, South Sudan, United States and even the world. I talked about different things like death rate and birth rate from South Sudan compared to the birth rate in the United Sates. I also talked about Chads population of people who don't have electricity and it was a lot of people as in 14 million people don't have electricity. I also had to write these facts and tell about how they involved what we're learning in class and a lot of it had to do with the change in population the bad way and good way such as birth rate and death rate. Finally, we had to predict the different pyramids for the different countries on how they would decrease, or rise slowly or rapidly.
