Correlation between birth rate and death rate.

Answer»
  • Birth rate and death rate are the important components of population change.
  • Birth rate is the number of live births in a year per thousand population.
  • Death rate is the number of deaths in a year per thousand population.
  • Population growth depends upon birth rate and death rate in a year.
  • Population growth occurs not only by increasing birth rate but also because of decreasing death rate.
  • When birth rate is more than death rate, population increases.
  • When birth rate is less than death rate, population decreases.
  • If both, birth rate and death rate is same then population is said to remain stable. However, the birth rate and death rate being same is only a hypothetical situation.
