Today in class, we took notes about things related to World War two. These are some things that I wrote down:
- The total fertility rate in the world is 2.5. This is above 2.1 which means the population is increasing.
- About 82 million people are added to the world each year. This is natural increase.
- Developing countries have high crude birth rates, total fertility rates, and infant mortality rates.
- A population pyramid is a bar graph that displays a countries distinctive population structure.
- More than 95 percent of the natural increase is in developing countries.
- TFR stands for total fertility rate.
- Dependency ratio is the number of people who are too young or too old to work compared compared to the number of people in their productive years.
- Developed countries have low crude birth rates, total fertility rates, and infant mortality rates.
I think that this unit will be easy for us to understand because of our prior knowledge on some of the subjects. Hopefully this will give us the upper-hand when it comes to taking our test!
