Aside from low birthrates and high birthrates, what can cause a countrys population due to decline ? a. immigration b. increase food supplies c. emigration d. diffusion

Hi there!

The answer is C. Emigration. 

Since a country's population might be decreasing because of Emigration, or citizens moving to another country to become residents of another country, the answer is C. Since all of the other options state that the population could increase, Emigration is the answer.

Hope this helps!
