Last blog I did, I didn’t really go over what I took notes
on during class. During class we discussed population pyramids. We can use
population pyramids to analyze growth (or decline) of fertility, mortality and
migration in cities. There are three basic shapes that the pyramids been shaped
as. The three shapes are the Christmas tree, a box, and lastly a cup. The Christmas
tree is meant to show us how the growth rate is slow. But the birth rate is
high. The box shows us that the population has a low infant mortality. But with
a long life expectancy. And lastly, the cup. The cup is supposed to show us the
people that the population has a low birth rate and a long life expectancy. Okay
now fast forward to now. We talked about this again today and just went over
more countries and seeing what population shape they fit in. I found this one
where there are so many men because most of them are in jail. I think this
subject is very interesting.
P.S.
After every blog I will have a Christmas count down
ONLY 47 MORE DAYS TILL CHIRSTMAS
