If immigration and emigration numbers remain equal, which of these could cause a slowed growth rate?

A. Increased birthrate

B. Constant death rate

C. Decreased birthrate

D. Constant birthrate

If immigration and emigration numbers remain equal, decreased birthrate could cause a slowed growth rate.

Answer: Option C

Explanation:

Let's basically understand that Immigration means that the people moving from their own native country to a totally different place to settle due to work, for studies etc. Emigration on the other hand is the people moving to a different native in a motive to get settled there.

Whether an emigrant or immigrant it is people moving from their own environment to a new place where they have to get accustomed to the entirely new climate, people and custom.

Though the immigrant and emigrant numbers remain the same the growth rate is obviously slowed down. It is because of the decreased birth rate as the new environment likely demands to meet the proper conditions for a human to multiply and reproduce.

Answer: C

Explanation:

If immigration and emigration numbers remain equal, decreased birthrate could cause a slowed growth rate.

Decreased birthrate always affects the numbers in terms of population. The less births there are, the smaller the number of people. Even if the death rate remains constant a decreased birthrate will slow growth of population.
