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
