Lots of notes

So, today in class we basically just went over new material as well as some things that we already have learned from the past unit. I will say it was very tiring for my hand because there was a lot of things to write down but welcome to high school, I guess. We went over total fertility rate again as well as infant mortality rate which wasn't anything new since we learned it from the last unit. Something else that we talked about was population structure which is basically just the population pyramid and we went over that in the last unit. We also learned something new which is dependency ration, which is basically the number of people who are too young or too old to work, compared to the number of people in their productive years. Overall, we were very productive in class which was a change since we just went over the test yesterday.
