WebAs per logistic model the population for year 2107 is estimated to 1.94 billion. This implies that the corrected population for the year 2107 would be approximately1.94 billion+ (-5.5 billion) = -3.56 billion. This value seems to unrealistic and treacherous. Hence the polynomial trend line of order 3 is discarded.
