Population+Growth+Rate

We looked at the natural population growth rate, but as we know, people immigrate (come to a country) and emigrate (leave a country). This is the overall population growth rate. Really, the effect on population of immigration is the same as the birth rate and emigration is the same as the death rate.

Example birth rate 40 death rate 39 immigration rate 80 emigration rate 50

The population growth is 31/1000 people per year.
