If births are low and many people leave an area, what can happen to the population?

Correct answer: The population may decrease

The direct answer is A: the population may decrease. Low births add fewer new people, and high emigration removes people from the area. These two factors both tend to reduce population size. The word “may” is accurate because deaths and immigration also influence the final population, but no information here guarantees that immigration or births elsewhere will offset the loss. A is correct because it matches the combined effect of fewer additions and more departures. B is wrong because the stated conditions do not support an inevitable increase. C is wrong because people leaving does not guarantee that many people will enter; emigration and immigration are separate movements. D is wrong because low births and out-migration do not make deaths zero. A useful population balance is: change depends on births minus deaths plus immigration minus emigration. Memory cue: fewer births plus more departures is a warning sign for population decline.
