Demographics is the practice of identifying groups of people in a population by their characteristics. Modeling of dynamic interactions in nature can provide a manageable way of understanding how numbers change over time or in relation to each other. Besides, the UN also publishes the Population and Vital Statistics Report quarterly which includes latest data on total population, total mid-year population and estimate of population for a recent reference year (Srinivasan, 1998:56).
