What factors can affect these rates

What you have listed are the statistics for determining basically anything that has to do with population.
You can look at nations such as China that have policies set in place where there is a limit on the number of children a family can have and see that they have a very small population growth or possibly a negative population growth, if the mortality rate and the migration rate exceeds the birth rate.
Additionally, it is possible for a nation to have a zero-population growth, where the death and migration rates basically even out with the birth rate.
There are any number or factors that affect any of these rates. If looking at it in a governmental way factors such as economic status, access to health care, access to food and clean water, access to pre-natal care. Any of those are factors in the birth and mortality rate. Additionally, personal beliefs can also come into play, such as belief in birth control. Many 3rd world nations have a very high birth rate due to the fact that their religious and ideological beliefs do not allow them to use birth control.
All, in all it's complicated question, that can't really be answered in a simple short paragraph. But, I hope that this information may be a good starting point for you to do more research.

Birth rates and immigration rates both serve to increase population size. Death and emigration rates decrease population size. If a population contains individuals with high fertility rates, this will boost population numbers, while low fertility rates will detract from population size.
The interplay of these factors will determine population size.

High birth rate: Increases population, affected by quality of medical care
High death rate: Decreases population, affected by quality of medical care
High Fertility: Increases population, affected by environment (pollution), age of population and access to healthy foods
Immigration: Increases population, affected by laws and demand for labor
Emmigration: Decreases population, affected by social stability, crime, wars, food supply

birth increase death dercreases migration can do both, and fetility can increase or decreases depending on what happens after.
