Definition: Population Explosion

A population explosion means very rapid growth of the population, much faster than economic growth. In India, this has mostly happened because of a high birth rate and a much lower death rate in recent times.

Formulae [1]

Standard Formula
  • For a given time interval:
    \[\text{Survival Rate}=\left(\frac{\text{Number alive at end of period}}{\text{Number alive at start of period}}\right)\]
  • The value ranges from 0 to 1 (or 0% to 100%).
  • Population growth rate = Birth rate – Death rate.
