The annual change in population in percentage leads to a surplus of births against deaths together with the balance of people entering and living the country. The growth rate, therefore, may be positive or negative depending on the burden that is imposed a given state through the changing needs. The rapid population growth is also likely to affect the surrounding countries in terms of sharing the resource.
