Today we started with the life expectancy.  Life expectancy means the average number of years to be livid by a group of people born in the same year.  A fact about that is that women tend to live longer then men.  Next we talked about the measuring of population.  Crude death rate:  Number of births per 1000 pf the population.  Crude death rate:  Number of deaths per 1000 of the population.
After that talked about RNI (Rate of natural increase)
~Produced by- the death rate from birth rate.
~Give us the annual natural growth rate- in % from- for a country or region.
Last thing we did was the net migration rate:  The difference between the # of persons exerting and leaving a country during a year.
