Open in App
Solution
Verified by Toppr

  • The world population has grown very rapidly because the death rate has gone down as a result of the growth of food supplies and the improvement of medical facilities.
  • Also, unlike the death rate, the birth rate has remained quite high.
  • The birth rate and the death rate are two factors that influence population change.
  • The birth rate is the number of live births per 1000 people while the death rate is the number of deaths per 1000 people.
  • Thus, the birth and death rates affect the balance of population.
