Demographic Transition Video Assignment

Kahn Academy Video
1. demographic transition shows the changing of a country's population growth rate as the country develops.
2. To get the population growth rate you take the new number minus the initial number, then divide it by the initial number then multiply that by 100 to get a percentage.
3.things that can cause a population to grow include the government offering incentives to people for having children, their faith-promoting large families to increase the number of followers it has and passing down the morals and ideas to your children which have a certain prestige that goes along with it.
Video From Dr. Kim Smith Ph.D.
1. We experience the same population growth that was experienced per year in the 1600s every 6 hours because our fertility rates are so high especially in developing nations.
2. In the times of stage 1 women and children were seen as property, and defined the wealth of men based on how many children they had.  The more children that they had, the higher the status of the family, and the more help that they had.
 3. In stage 2 the population starts to increase sharply because the mortality rates go down because of bettering in technology that helps the economy although the birth rates stay high.  this is called a cultural lag because even though the mortality decreases people still have large amounts of children.  this is because the technology changed faster than the culture's ability to adapt
Why populations grow
1. One way that we can measure population growth is by measuring the doubling time, or how long it will take a country to double its population.  this can be calculated by dividing 70 by the growth rate.
2. In the third stage of the demographic change model, the death rates continue to decrease as do the birth rates which allows the population to increase but at a slower rate. This can be caused by increased living standards, better health care, and a movement towards urban life making it unnecessary to have large families.
3. In the 4th stage of the model booth birth and death rates are low which causes the population to equal out.  this is seen in most of the economically advanced nations around the world.  this is because these countries have better health care, more education, and more women in the workforce.

I think that the video by Dr. Kim Smith Ph.D. was the most helpful to me. This is because she was easier to understand than the other videos, and she offered supplementary information that helped to make the data easier to apply and understand.
