Blog Post #25 - Why do people migrate?-

     Today in class we took more notes on the powerpoint dealing with population. The key question that we took notes on today was "Why do people migrate?". People migrate because of push and pull forces. Push forces make a group of people want to leave a country. Some examples are a civil war, environmental degradation, unemployment or underemployment, and religious or ethnic persecution. Pull forces make a group of people want to enter/live in another country. Some examples of pull forces are better economic opportunity, better health services, religious freedom, and political freedom. The next thing we talked about was Total Fertility Rate (TFR), which is the average number of children born per woman. For the population to remain the same, the TFR must be 2.1. If it's higher than 2.1, the population rises, and if it's lower than 2.1, the population falls.  The world TFR is 2.42, The U.S. TFR is 2.01, Nigeria's TFR is 6.89, and Japan's TFR is 1.40.
