When we first arrived in Human Geo today we took a test on
the video we watched about the Lost Boys. Payton and I, had shadows and Mr. Schick
let them go to the cafeteria because class was going to be boring. We learned
about population pyramids after we took the test. Population pyramids help us
analyze growth or decline of fertility, mortality, and migration in cities.
There are 3 basic shapes of population pyramids. The Christmas tree, the box,
and the cup. The Christmas tree chart shows developing nations that have slow
growth rates, high birth rates, and short life expediencies. An example of this
is Namibia Bangladesh. The box chart shows developed nations that have a low
infant mortality, slow population growth, and long life expediencies. An
example of this is America. The cup chart shows developed nations that have a
shrieking population, low birth rates, and long life expediencies. An example
of the box chart is Japan.
