Explain how birth rate, immigration, death rate, and emigration affect population growth.
frez [133]

Answer: They affect population Growth because they highly influence the number of people in the community.

Explanation:

Birth rate is something that varies depending on culture, some cultures encourage people to have more kids, so in that specific community the birth rate will be higher, and a higher birth rate, as those people age will lead to a higher death rate. Changes affects population growth because moving (in both emigration and immigration) there is a change of environment.

Emigration may lead to a lower birth rate, as it has more to do with people moving from rural areas to city areas. Since raising kids is expensive, especially in cities, they might have less kids, therefore affecting population growth.

Immigration also highly affects population growth because it encourages a high movement of people. Since people are coming from all over the world and choosing to set in an specific area, that area will have an increase in population growth.
