Oct 9th Human Geography Class

Today was the last day of reviewing before the exam. Tomorrow is the exam day which is very important day. What we reviewed for last is we reminded the meaning of word "Total fertility rate", it means average of the number of children born to a woman. We also reviewed some informations about the population pyramid. This is the graph that shows how many people are in the range divided by certain ages. This shows if the country is low birth rate and high aging or high birth rate and low aging. The most ideal graph is rectangular. Rectangular graph means populations are distributed in all sections of the range. In these societies social issues like a job shortage are not huge issue. For istance U.S. is the example for rectangular society. Which is the first place country in the world.
