SEPT 25，2014 measuring population

Today's human geo class , we talked about measuring Net Migration Rate, measuring population and Growth rate.
Net Migration Rate: the difference between the number of persons entering and leaving a country during a year 

growth rate: The number of deaths subtracted from the number of births a country as a year.

measuring population

Canada had 5.65 migrants in 2013 and 5.66 in 2014.

U.S had 3.62  net immigration rate in 2013 and 2.45 now.

I was having a retreat on the day that talked about these things, so i was not in class and that's new things for me.
