Test Review

        Today in class we went over everything in this unit for our tests. We went over all the vocabulary like life expectancy, crude birth rate, crude death rate, net migration rate, immigration, and emigration. We went over how if you know the crude birth and death rate you can also figure out the natural increase of population. We also went over that if you subtract the emigration rate from the immigration rate you get the net migration rate. The class learned that infrastructure is what a society needs to build a good country. An example of some countries that are dying faster than giving birth are Japan, Germany, and Italy.
