test review

Today in class we reviewed what is going to be on the test on Monday. It is going to be on how many people are on the planet right now which is 7.6 billion people and where most of the population growth rate takes place which is 90% in developing countries of Africa, South and East Asia, and Latin America. It is also going to be on how long it took us to get to our first billion and crude birth and death rate, and rate of natural increase (RNI). We will also need to know net migration rate, immigration, emigration, push and pull forces, total fertility rate and what number it must be to remain the same that number is 2.1
