can be potentially more important for the next generation than it is for us. The issue is birth rate or population‚ what it is now and what it will be in the future. First of all‚ what is birth rate? The birth rate is the total number of births per 1000 of a population in a year. As you may know‚ by subtracting the death rate from the birth rate we will result in the rate of population. Here is a display of the birth rate from 1950 to 2015. Year Birth rate 19501955 37.2 19551960 35.3 19601965 34.9
