Blog Day Forty- Six: In-Class Assignment

Today in class we watched three videos and had to pick which one was our favorite. Here is my assignment.

Why Populations Grow

1.  In European countries, women are having fewer children than the replacement rate and the only thing keeping those countries population up is the high net migration rate. 
2.  A country's birth rate can decline because of the fact that families no longer live on farms, so parents dont need to have as many kids to use for labor work. 
3.  Most more economically developed countries are in stage four of the demographic transition model. 

Khan Academy Video

1.  The second stage of the demographic transition model is seen as a country reaches its developing stage. 
2.  In stage three of the demographic transition parents tend to have less children because of contraceptives and a bigger social trend towards smaller families. 
3.  The fifth stage of the demographic transition model is a speculation and some believe that the world population will forced to stabilized because of a potential resource shortage. 

Video From Kim Smith, Ph.D.

1.  The world's population now grow 67,000 people every 6-7 hours
2.  In stage three of the demographic transition, fertility rates drop because children are redefined as liabilities rather than assets. 
3.  The space between the fertility rates line and mortality rates line on a demographic transition model is called the demographic trap. 

My favorite video was the Khan Academy video. I choose this video because it was the right amount of talking and graphics. The video about why populations grow was hard to hear and understand. The video from Kim Smith was okay but it only showed occasional pictures and was mainly just a lecture. The Khan Academy video was nice because you could see how the population pyramids differ in each stage and got to visualize on screen what the lady was talking about. Out of the three videos the Khan Academy video was my favorite.
