Question

Answer 1

Answer: Higher infant mortality rates cause higher fertility rates.

Explanation:

Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.
