There are four major factors that affect population growth:

Birth rate : The number of births per 1000 people in a year. This has a positive effect on population growth. This makes sense, as people being born adds to the population.

Death rate: The number of deaths per 1000 people. This has a negative effect on population growth. People dying lowers the total population.

Immigration : The number of people entering the population. This has a positive effect on population growth. People entering the population increases it.

Emigration : The number of people leaving the population. This has a negative effect on population growth. People leaving the population decreases it.
