Happy Birthday Angela

Today in Human Geo, we took a test on the documentary, “God Grew Tired of Us.” It wasn’t too hard.  We also sang “Happy Birthday” to one of my classmates, Angela. She brought in munchkins from dunkin’ donuts, so that was pretty cool. Then, we started to take notes on Population Pyramids.

Population pyramids- analyze growth (or decline) of fertility, morality, and migration in cities.

Men are on the left of the pyramid, and women are on the right.

The pyramid basically shows the percentage of population per age, for males and females.

The pyramid is broken up into three sections:

1.      0-20: kiddos

2.      21-64: economically active

3.      65-80+: the oldies

There are three basic pyramid shapes:

1.      The X-mas tree

a.       Developing nations

b.      Slow growth rate

c.       High birth rate

d.      Short life expectancy

2.      The Box

a.       Developed nations (slow growth)

b.      Low infant mortality

c.       Slow population growth

d.      Long life expectancy

3.      The Cup

a.       Developed nation (negative growth)
