What effect can positive net migration have on the total population of an area?

Answer and explanation

Correct answer: Population may increase

Direct answer: C, the population may increase. Net migration compares the number of people entering an area with the number leaving it. It is calculated as in-migration minus out-migration. When more people enter than leave, net migration is positive. These additional residents are added to the existing population, so the total population can rise, even if births and deaths are unchanged. Option A is wrong because positive net migration adds people rather than removing them. Option B is wrong because migration changes the number of residents. Option C is correct because a surplus of incoming people increases the population. Option D is wrong because migration changes population, not the physical area of the region. Memory cue: positive net migration means “more in than out,” so think of an upward effect on population.
