migration

Today in Human Geo, we talked about birth rates and death rates per 1000 of the population. We learned that the net migration rate is the difference between the number of people entering and leaving a country during the course of a year. There is net immigration and emigration and a good way to remember it is immigration is going in with an i and emigration is exiting and has an e. There are also many ways for migration, for example if people have a pushing force like a civil war, environmental degradation, unemployment/under employment, or religious/ethnic persecution. Other reasons people could migrate would be a pulling force including better economic opportunities, better health services, religious freedom, or political freedom. At the end of class, we began discussing the total fertility rate which is the average number of children born per woman. We found that in order for the population to remain steady, its TFR would have to be 2.1. Anything over would cause an increase in population, and anything under would cause a decrease in population.
