Population Pyramids
Overview:
In this exercise you will assess population pyramids that have been stored by the U.S. government. While these visual representations of the population show the age and sex structure of populations in our world. This information is also helpful in terms of foreign and international policy. For example you may notice that LDC countries have a large number of people under the age of 15? If this is the case what are the types of policies that a LDC country should have? Additionally, you may notice that the countries in certain stages of the DTM have particular shapes. For instance a Stage 2 country in looks more like a triangle, while an aging country is going to look more like an inverted triangle. These patterns are important to notice in reading population pyramids.
