Predict what might happen to a population that is experiencing little immigration and emigration, low birth rate, and high death rate.

The population will later, cease to exist.

A low birth rate and a high death rate means that more people are dying than being born.

Therefore the population will decrease until there is nobody and it will cease to exist.
