Rating of Death to Life

Today in class we learned many things. First we learned about crude birth rate. That is births per 1000 people of a population. Then there is the crude death rate. The deaths per 1000 people of a population. After that we learned of RNI (rate of natural increase), that is subtracting the death rate from the birth rate. The net migration rate is the number of people entering and leaving a country during a year. There are many reasons why people migrate. like a civil war, environmental deflation, underemployment or unemployment, and religious persecution. There is also a reasons people pick where they migrate to. They migrate to certain places because better economical opportunities, better health services, religion freedom, political freedom. finally there is the TFR (total fertility rate).
