When people entering an area are more than people leaving it, what happens to population?

Correct answer: Population may increase

Direct answer: B, the population may increase. To solve this, compare inward migration with outward migration. People entering an area are added to the number of residents, while people leaving are subtracted. If arrivals are greater than departures, the migration balance is positive, so the area can gain population, assuming other factors do not completely reverse the effect. Option B is correct because it describes this likely result. Option A is wrong because it would normally be associated with more people leaving than entering, though births and deaths can also affect the final total. Option C is wrong because a positive migration balance cannot make the population zero. Option D is wrong because the physical area of a place does not disappear when its population changes. Memory cue: more in than out means a positive migration balance.
