If emigration is high from an area, what can happen to local population?

Answer and explanation

Correct answer: Population may decrease

Direct answer: A, the population may decrease. Emigration means people leave their usual area or country to live elsewhere. The reasoning is simple: people who move out are removed from the local population count. If the number leaving is greater than the number entering, and births and deaths do not offset the difference, the local population falls. B is wrong because out-migration does not automatically double a population; it usually removes residents. C is wrong because the departure of people does not necessarily raise the birth rate, which depends on births and the population structure. D is wrong because a Census is an official population-counting exercise and does not stop merely because people migrate. The word “may” matters: other factors can change the final result. Memory cue: emigration means “exit,” so people go out.
