*Net migration rate (NMR)---
Number of immigrants - Number of emigrants = NMR
If NMR is positive, there is more people entering the country.
If NMR is negative there is more people leaving the country. (Mexico)
*Total fertility rate (TFR)---
TFR is the number of children born per mother. if the number is 2.1 it will stay the same.
It is 2.1 because that cancels out the mom and dad and .1 is the average so that all the people that die from war and other causes will regenerate.
