If many people come from outside into an area what may happen?

Answer and explanation

Correct answer: Population may increase

Answer: A, the population may increase. When people come from outside and enter an area, they add to that area’s population. This movement is called in-migration. If the number of people arriving is greater than the number leaving, and births and deaths do not offset the change, the population can rise. Option A is correctly worded with “may,” because the final population also depends on out-migration, births, and deaths. Option B is wrong because arrival normally adds people rather than guaranteeing a decrease. Option C is wrong because migration does not make the birth rate zero; births can continue independently. Option D is wrong because death rate is only one demographic factor and is not the only possible cause of population change. Memory cue: people entering are added to the receiving area; people leaving are subtracted from it.
