Test Day and Pop pyramids

Today in Human geography, we took our test on God Grew Tired of Us. The test was really easy especially if you paid attention to the movie. After the test, we began something new. We talked about population pyramids. Population pyramids are used to analyze growth/decline of fertility, mortality and migration in cities. There are three types of population pyramids. They are Christmas Tree, Box and Cup. Christmas Tree shaped like a Christmas tree is when a countries growth rate are slow, the birth rate is fast and the life expectancy is low. Examples are Chad and Zimbabwe. The box which is shaped like a box is when there is low infant mortality, slow population growth, and a long life expectancy. Examples are United States and Canada. The cup which is shaped like a cup is when there is low birth rates, a shrinking population and a long life expectancy. Examples are Italy and Japan.
