If births are more than deaths and out-migration is low, what will happen to population?

Correct answer: Population is more likely to increase

Direct answer: B is correct. Population change can be understood by considering births, deaths and migration. When births are greater than deaths, the area has a natural increase. If out-migration is low, relatively few people are leaving, so this increase is not greatly reduced by movement out of the area. Therefore, the population is more likely to rise, assuming no unusual factor reverses the result. A is wrong because a decrease would normally require deaths to exceed births or substantial out-migration. C is wrong because the stated conditions do not make the population zero. D is wrong because population means the number of people, whereas area means the extent of land. The phrase “more likely” is appropriate because population change can include other factors. Memory cue: more births than deaths adds people; fewer departures allow the increase to remain.
