Name the four factors that affect population growth. Then, define these factors

Answer: Four factors which affect population growth are birth rate, death rate, immigration and emigration.

Explanation:

Birth Rate: The number of babies which are born per year within the population. This can affect the population positively or negatively depending on whether it increases rapidly or it normal such as some Asian countries have reduced the number of birth per individual citizen due to high birth rate which lead to drastic increase of population.

Death/mortality rate: The number of people who dies within the population per year. if the death rate equals the birth rate then an almost state of equilibrium may be managed provided emigration and immigration is also balanced.

Immigration: The number of people who enters into the country or population. If more people enters the country this may increase the population rapidly.

Emigration: The number of people who leave the population or country.
