Population

Today we talked more about the population of the whole world. First we talked about the different types of rate such as crude birth rate, crude death rate, rate of natural increase, and Net Migration Rate. Crude birth rate is number of births per 1000 of the population which is the opposite of crude death rate. We also learned that the rate of the natural increase is produced by subtracting the death rate from the birth rate and this gives us the annual natural growth rate in percentage form for 
country or region. we also learned about Net migration net which is the difference between the number of persons entering and leaving a country during a year. Finally, we learned that an excess of people leaving the country is net emigration and the people entering is net immigration.
