The four factors are birth rate, immigration, death rate, and emigration.

Birth rate and immigration add individuals to the population, increasing the size.

Death rate and emigration remove individuals to the population, decreasing the size.

(birth rate + immigration) – (death rate + emigration) = population growth.

They are;
Birth rate
Death rate
Immigration
Emigration

Birth rate is the number of babies born at a particular time. Increase birth rate leads to increase in population. While a decrease leads to a decrease in population.
Death rate is the number of deaths at a particular time. Increased death leads to population decrease and decreased death leads to population increase
Immigration is the movement of people into a place. Increased immigration leads to high population
Emigration is the movement of people out of a place. Increased emigration leads to low population.
Hope I helped. Good luck
