Name and briefly explain the three primary causes of the enormous population growth in the United States between the years 1860 and 1910. please help

The change in the population from births and deaths is often combined and referred to as natural increase or natural change. Growth through natural increase occurs when the birth rate exceeds the death rate.

Migration is the movement of people from one area to another. It is often expressed as net migration, which is the difference between how many people move into and out of an area. When net migration is positive, a population has more people moving in than out. We split migration into domestic migration and international migration.
