However, for the developing countries like India, population explosion is a curse and is damaging to the development of the country and it’s society.

The death rate is the ratio between the number of deaths and individuals in a specified population and time (Miller, 253).

The population change is calculated by the formula: Population change = (Births + Immigration) – (Deaths + Emigration) The recent increase in the world population has been caused due to the following major reasons: 1.
