Population Pyramid

Today we took a quiz on the God Grew tired of Us film.  After that we started to learn about the population pyramid.  There are three types of population pyramids.  There is the Christmas tree, the box, and the cup

The Christmas tree usually matches up with developing nations.  For an example, African countries.  In Africa, there is a very high birth rate and because of many diseases, there is a low life expectancy.  The box is usually developed nations with slow population growth, and a long life expectancy.  an example of the box is the United States. The cup is a developed nation with a low birth rate, and a long life expectancy.  There are more elders than young kids.  An example is Japan.
