Review for test tomorrow

Today in class we went over the unit in desperate preparation for the test overmarrow. A couple of questions confirmed to be on the test are using statistics and math to find a net increase in certain topics such as migration, population increase, and fertility. There will also be a section where we have to use the CIA World Factbook to find answers. A few questions that are probable to be on the test overmarrow are the number of people on Earth currently, that the majority (90%) of the population growth takes place in developing nations, that in 1804 the population reached a billion, and the rate of increase flatlined around 1974-2011. A few more good things to know are that women, almost in every country, live longer than males (on average), the definitions of crude birth, crude death, and RNI (rate of natural increase), net migration rate, different push and pull forces and countries that have them, and the total fertility rate. Also, keep in mind that the TFR must be 2.1 for constant maintaining of the population.
