Explain how birth rate, immigration, death rate, and emigration affect population growth.

Population growth is exactly what it sounds like, the growth of the population.

There are several things that contribute to population growth, whether it's increasing, or decreasing.

Birth rate rising or decreasing would affect the number of people in the world, or in a country, and this could lead to over-population if too many people are born in the same amount of time.

Death rate would decrease the population, because you're losing people who are apart of the population.  

Emigration would affect the population growth in an area, such as the united states, because it's adding people to an already highly populated country. Population numbers would go up as more and more people emigrate to the area.  

Hope this helps! Let me know if I need to clarify or add more info if this isn't enough!!!
