The concepts related to population growth are birth rate, death rate, and survival rate. 

  • Birth rate: The number of births occurring per 1000 of the living population during a year is called as Birth rate. It is also called as “fertility rate”. 
  • Death rate: The number of deaths occurring per 1000 of the living population during a year is called the Death rate. It is also called as “mortality rate”. 
  • Survival rate: Survival rate shows the actual rate of population growth. It is calculated by deducting the Death rate from the Birth rate i.e. Survival rate = Birth rate – Death rate.
