18. © 2006 Population Reference Bureau Lets see if you can do this. Find 2 population pyramids on the internet. List the population stage that each country is in. List three assumptions we can make about each country just by looking at the pyramid. –Assumptions about the economy of the country –Assumptions about the prosperity of the country –Assumptions about the future struggles of the country –Assumptions about the future population of the country. –Assumptions about the history of the country. Compare the population pyramids to each other Each assignment will be given a mark out of 5
