The factors that accounted for the population growth are birth date, death rate, immigration, and emigration.
The following information should be considered:
- The birth date deals with the no of babies born at the particular time period. If there is an increase in the birth rate, so the population should increase and vice versa.
- The death rate deals with the no of deaths during a particular time period. If the death rate is increased so the population should decrease and vice versa.
- Immigration deals with the movement of the people are in the place. If immigration is increased so the population should be high.
- Emigration means the movement of the people that are out of the place. If it is increased so the population is decreased.
Therefore we can conclude that the factors that accounted for the population growth are birth date, death rate, immigration, and emigration.
